OCRA Membership Meeting, August 13, 2018

Introductions:

Treasurer Report:  Dan (KR4UB)

Club balance was reported.

Dan created a new attendance sheet.  He also went through old club records to capture the date members joined.  There are many current members who helped establish the club in the early 1990s, when the club was called the Orange County Wireless Pioneers.  Steve Jackson (KZ1X) was the spark plug for establishing the club.  The first meeting was in the community room of OWASA.  Anyone with club records, please let Dan know. Dan will scan and add the content to the site, which will help preserve club records.

Dan has a repeater still occupying space in his basement.  The current repeater market in Durham and Alamance is rather saturated.  However, as Chatham County is growing, so is the need for communication towers.  Nick (KA1HPM) mentioned that the county is planning to install several new towers for 2020.   There may be opportunities to relocate the repeater to a tower in Chatham County for amateur radio and CERT usage.

Field Day results:

While radio propagation was sketchy, we were able to accumulate 2000 more points this year over last.  Every station, minus 80 meters, was able to increase their score, with digital exceeding last year by over 1000 points.   This year’s numbers will change slightly as Dave (W4SAR) thoroughly combs the combined log to eliminate duplicate contacts, fix broken exchanges, and eliminate broken exchanges that cannot be made good:

For more detailed information on Field Day, we encourage you to read the July 2018 DFMA newsletter. https://www.dfma.org/TheLink/2018/Link1807web.pdf

Show and Tell

Steve (KZ1X) was cleaning out an old radio box and brought in a Micron SWR field strength meter, which may have been purchased as the old Radio Shack in University Mall.  The Micron measures the amount of signal transmitted by your antenna system, and a signal pattern can be plotted by taking readings around your antenna.  The meter covers 3 to 30 MHz and can handle up to 1KW.

He also brought alligator clips with magnifier glass used for splicing wire and adding connectors.

Dave (KW4XL) brought in several 3D printed products, including a raspberry pi hotspot case and working crescent wrench.

The next membership meeting is scheduled for Monday, September 10.  Hope to see you there!

OCRA Membership Meeting, July 9, 2018

Meeting Attendance: 28

Treasurer:

  • Club balance is still strong. Current membership is 79, with 24 requiring renewal.  The club has added 17 new members this year.
  • Field Day – Thanks to all who assisted, supported, and participated in the Field Day food preparation and delivery. The pre-paid approach for Saturday’s evening meal and Sunday’s breakfast was very successful.  For Saturday’s meal there were 44 pre-paid with 6 people paying at meal time.  Likewise, for Sunday’s breakfast there were 36 pre-paid with 4 people paying at meal time. The success of meal pre-pay may become a new payment model for future field day meals.
  • Overall, the club profited $174 from meals, which will be added to our club coffers.

Field Day (FD) Recap:

Dave (W4SAR) provided a comparisons of 2017-2018 point totals.  For 2017 the total point was 19,760.  For 2018, we had an estimated total of 21,635.  Dave should have final 2018 totals in the next several weeks.  Congratulations to all for the great work securing the additional points…and the fun had by all.

This year, the Digi mode was a good success.  Dan (KR4UB) mentioned that Digital radio mode success in amateur radio has been partly attributed to the work of Joe Taylor (K1JT), who developed the WSJT-X software.  Joe is a noble prizing winning physicist, who has focused the past two decades on weak signal communication.  Joe is the developer behind several popular digital protocols like FT8 and JT65.

General FD Observations:

  • Less interference on 40 and 15 SSB than years past.
  • Accessible stations in garage worked well for all.
  • N1MM network may require piloting the software and associated computers a few weeks prior to FD. This may help reduce complexity, however, much of the issues are not the result of the application.  Rather, the issues are more likely attributed to the Microsoft OS and configuration of personal computers. Other clubs purchase refurbished PCs for FD from NewEgg to reduce configuration mismatch.

Band Captain Comments:

  • 40/15 SSB propagation and noise on the bands most of Saturday. By Sunday morning the bands opened with much less noise.
  • CW worked well…3 stations covered all night. Better scheduling provided coverage through the morning hours.  Power was more stable this year over lasts.
  • 20 SSB – had similar propagation and noise issues like other SSB stations. The station ran on solar power directly or from batteries recharged by solar throughout the entire FD.
  • 80 SSB did not have as many operators as years past. Was difficult getting confirmation due to static on the receiver.
  • Digital was well covered and enjoyed throughout the event. However, next year more comfortable seating will be needed.
  • VHF was challenging, but the 5 element Yagi provided a noticeable return on the points.

FD Logistics

  • For the larger antennas, a dedicated spotter on point for ensuring safety should be available, with agreed upon standard communication and terms. Additionally, a tower safety demonstration and additional guide wires for support may reduce operational risk.
  • Replace the wood antenna support “walk up” with metal. This will reduce the likelihood of the wood splitting and causing the tower to fall and potential hurt people.
  • The scheduling spreadsheet helped ensure adequate coverage of stations throughout the event.

Should we plan to add a Sunday lunch? Please reply to this post with your suggestions. We would enjoy reading your ideas!

OCRA Board Meeting, May 28, 2018

++ Please Note: Field Day – Prepay Meal explained below. 

Attendees:

Dave (W4SAR), Karen (KD4YJZ), Dee (KU4GC), MK (W4MKR), Steve (W3AHL), Dan (KR4UB), Keith (W1KES), Wilson (W4BOH), Lad (W4ORD), and Bill (N8BR)

Field Day:  Prepay Meals

For this year’s 2018 Field Day, OCRA and DFMA are asking attendees to prepay ($5) for the Field Day June 23, Saturday 5 PM super and June 24 Sunday Breakfast (will refund if you must cancel, provided written cancellation is received before the food purchase date noted below.)  This is necessary to avoid the club losing significant money or, asking members who do show up to pay a higher amount to cover those who do not.

Prepayment authorizes the club to buy food on your behalf and can be by cash or check at the next meeting or mailed.  PayPal costs for many small payments is excessive and precludes use of that feature. Meal orders must be received by OCRA by June 18th.  Vegetarian meals are available. If you pay and later find you must cancel, send an email to treasurer@ncocra.org prior to the June 19th food order date, and your payment will be refunded or, you can use it as a tax deductible donations to the club, or extend your memberships, hihi.

The food purchase committee consisting of Lad, MK,and Dee will work with Jean (KR4UB ‘s XYL) to coordinate logistics.  We are seeking donations from Food Lion and possible Costco, but will reconsider whether donations are needed for next year.

DFMA Hamfest: 

The DFMA Hamfest was a good success.  OCRA club table netted $52.  The Volunteer Examiner (VE) session was successful with outcomes for 2 Extra, 4 General, and 3 Technician.

Repeater:

OCRA Board has decided to limit pursuing UNC campus for a repeater location. Instead, the priority will be to keep the 442.150 repeater active and on the air,  and ensure we have a trusted, hot-swappable repeater for backup.

We are actively seeking interested OCRA members to join the Repeater “team.”  This is a great opportunity for interested Hams to learn more about maintaining and supporting repeaters in the local area. If interested, please leave responsed to this post, or send an email to board@ncocra.org.

 

OCRA Board Meeting, April 30, 2018

Attendees:

Dave (W4SAR), Karen (KD4YJZ), Dee (KU4GC), MK (W4MKR), Steve (W3AHL), Dan (KR4UB), Keith (W1KES), Wilson (W4BOH), Lad (W4ORD)

Financials:

Balance statement is strong.  Current membership with dues current is 74.

Establish a Board email group – will use to share and approve meeting minutes

Dan (KR4UB) has created a new membership sign up form to assist in managing existing and new members.  We need to announce at next membership that OCRA stickers are available for $5.

Repeater:

Dan (KR4UB) will contact Alex at UNC to determine if they are able to provide any financial assistance.  The level of assistance will help determine our next steps.  There may be opportunities to locate and share the repeater with Chatham County CERT. We need to be diligent in discussions and move forward with a repeater decision in the coming months.

Public Service:

Steve (W3AHL) mentioned that public service activities are down this year.  However, John Stone mentioned that several new events have been added to the schedule. If interested in sharpening your ARES or CERT skills, these events are great learning opportunities.

Durham Fest:

There is work session Friday May 25 from 6:00-8:00 for setup.  Saturday morning, setup assistance will be needed starting around 7:00 AM.  The ham fest will start at 8:00 AM and end around 12:30 PM, with tear down starting shortly thereafter.  Tables are $12 and space available for $8.

Early registration tickets are available and will be registered for $50 drawing.  VE session will also be part of the HAM Fest.

Decision:

Board agrees to spend $24 for two tables.

Field Day:

Planning is ongoing. Antenna designs and locations will be finalized in the next month.

Lad will contact Kelly to determine available, costs, and logistics for providing diner around 5:00 PM on Saturday night.  This would reduce the dependency on band captains and other participants in managing meal logistics.

Sunday morning breakfast will still be provided by members.

Google adds Morse code input to Gboard

Google  is adding morse code input to its mobile keyboard. It’ll be available as a beta on Android later today. The company announced that new feature at Google I/O after showing a video of Tania Finlayson.

Finlayson has been having a hard time communicating with other people due to her condition. She found a great way to write sentences and talk with people using Morse code.

Her husband developed a custom device that analyzes her head movements and transcodes them into Morse code. When she triggers the left button, it adds a short signal, while the right button triggers a long signal. Her device then converts the text into speech.

Google’s implementation will replace the keyboard with two areas for short and long signals. There are multiple word suggestions above the keyboard just like on the normal keyboard. The company has also created a Morse poster so that you can learn Morse code more easily.

As with all accessibility features, the more input methods the better. Everything that makes technology more accessible is a good thing.

Of course, Google used its gigantic I/O conference to introduce this feature to make the company look good too. But it’s a fine trade-off, a win-win for both Google and users who can’t use a traditional keyboard.

OCRA Club Meeting April 9, 2018

Introductions:

Treasurer Report: 

We have a strong financial balance.  Current membership listing is located under the Membership tab.

Repeater Update:

Dan (KR4UB) explained that installing the repeater at UNC is not cost effective at this time.  The club is seeking a cost sharing arrangement with UNC.  More information will be known later this Spring.

General Reports:

  • Raleigh (RARS) Fest – The Club sold a few items totaling $40 dollars. Thanks to Steve’s (KZIX) $67 donation at the meeting, we added a total of $107 to our savings account.
  • Durham Fest is Saturday, May 26, 2018. Tickets are now available.   – Tickets available.  Link to site with Dates.
  • The Tar Heel 10 Miler is April 21st. The Tar Heel 10 Miler and Fleet Feet 4 Mile run both start at the UNC Chapel Hill Bell Tower running you through the heart of downtown Chapel Hill, the historic Rosemary district, the UNC Campus and the beautiful Gimghoul neighborhood. Steve (W3HAL) has inquired with race management regarding amateur radio support.  We should have an update in the next week or two.
  • A VE Session is scheduled for Saturday, April 14th at the Orange County Emergency Services Center. Thanks to Paul (N2XZF), Nick (KA1HPM), Andy (W4KIL) and Dave (NA4VY) for their assistance.
  • OCRA has experience difficulties managing our emails distribution with Yahoo. As such, earlier this month Dave (W4SAR) transitioned our Yahoo account to Groups.io, which provides a more mature platform providing more features and easier group management.
  • Field Day is approaching…June 23 and 24. We are planning to retain the same band captions, but will move Digital to field, which will make the barn available for more easily accessible stations. We plan to leverage the NCOCRA blog calendar to manage station coverage throughout the event.  Still looking for a “few good hams” to manage the food committee.  If interested, please let Dave (W4SAR) know.

Program:

Vertical T-Wire Top Antenna 80 and 160 Meter Vertical and 80 Meter Dipole

Wilson was inspired by the  Bouvet expedition to build a “T” Top Antenna for 80 and 160 Meter.  While the Bouvet expedition was not successful (Inclement Weather) the “T” antenna was successful.  For more information on the Antenna, please reference Dan’s (KR4UB) blog article, “The Lurid Details of a W4BOH antenna for Bouvet.”

For more information on Low-Band DXing, Wilson recommends John Devoldere (ON4UN) book,  Low-Band Dxing: Antennas, Equipment and Techniques for DXcitement on 160, 80, and 40 Meters.

An overview of the EZNEC design and analyzer measurements of W4BOH’s 160/80M vertical/dipole antenna, as of mid-March is located at:
https://groups.io/g/OCRADFMA/files/Antenna%20Designs/W4BOH%20160M%20&%2080M%20Vertical%20T-Wire%20Elevated%20Radials%20L-Netwk%20&%2080M%20Dipole%20Project%20031218.pdf

Andy (W4KIL) presented a 5W CW Transceiver kit by QRP Labs.  The transceiver is a feature rich, high performing, single-band 5W CW transceiver kit, with WSPR beacon and built-in alignment/test equipment for only $49.

OCRA Board Meeting, February 26, 2018

Attendees:

Dee (KU4GC), MK (W4MKR), Dave (W4SAR), Karen (KD4YJZ), Wilson (W4BOH), Steve (W3AHL), Dan (KR4UB), Keith (W1KES)

Treasurer Report:  Balance is still strong, current membership is 77 active members.

Tower Report

Tower Engineering provided a quote to complete the drawings, gain state approval, and install the antenna.  However, the quote is cost prohibited for the club.  Dan (KR4UB) and Steve (W3AHL) will schedule time with UNC to discuss a possible cost sharing arrangement.

Meeting Development and Membership Encouragement

 Meeting development and membership encouragement is a primary focus this year.  As expressed in the last Membership meeting, and again in this Board meeting, we are seeking ideas on how to improve the meeting experience.  Below are a list of suggestions and actions being taken to enhance our membership meetings.  We encourage members to provide feedback and get involved.

Amateur Radio Club Development is based on establishing and maintaining interpersonal relationship.  We encourage members to get involved in the club.  If you have interests, skills, or experiences you wish to share with new hams, or the general membership, please let any of the Board members know.

Suggestions and Actions:

  • Keith (W1KES) contact the Chapel Hill High School to begin discussing presenting Amateur Radio to the Physics class.
  • John (KX4P) will be facilitating our next meeting program. The topic should be finalized later this month.
  • Kurt (N2PCC) is working with published schematics to build his own 40 meter Benson small meter. Once complete he is willing to be program topic.
  • Dan (KR4UB) is installing software to the NCOCRA blog that will allow members to add pictures directly to the blog.
  • Dave (W4SAR) is establishing an Elmer resource pool. After Membership introductions, we need to ask if there are questions, or if anyone needs assistance.  If so, we can assign an Elmer to assist.
  • Wilson (W4BOH) has offered his barn for wheel chair accessible for Field Day. The barn has a concrete floor and would be more wheel chair friendly than the grass.
  •  The board suggested scheduling a portable station at a local park to provide a demonstration and educate new hams and the public to the wonderful world of amateur radio.

Dave (W4SAR) will take the suggestions above and those offered at the last membership meeting to develop a plan, which he will communicate at the next membership meeting.

We want to hear from you.  Please provide a suggestions by replying to this post.  73

OCRA Membership Meeting, February 12, 2018

 Introductions:

Suggestion was given to shorten introductions to just name, call sign, and location.  This would reduce the overall meeting time.  However, we want to encourage new people to talk about their experience and interests.

New hams will receive a free year membership to OCRA.  This is a great deal that we need to market better.

Treasurer:

Strong financial balance with 70 currently paid members.

Website:

Dan (KR4UB) has added a new document repository on the site.  We encourage members to post radio related documents that would benefit the membership. Likewise, if there are informative amateur radio YouTube videos, please post a link.  Our intention is to make our Website a great starting points and interactive resource for sharing ideas, experiences, and events.

Similarly, Google calendar is now on the site.  Under the “Events” section, located on the top ribbon, you can keep informed about when and where Membership and Board meetings, local nets, public service opportunities.

Repeaters:

Dan (KR4UB) and Steve (W3AHL) are working to get a quote to determine the feasibility for re-establish the repeaters back on the UNC campus.

ARES/Public Service:

Steve’s (W3AHL) recently has been absence on Saturday morning nets due to other public service commitments.  Mark your calendars now, the Tar Heel 10 Miler will occur April 21. Please clear your schedule and get your HT ready!

Dave (W4SAR) is near the top ranking of VE sessions participation in the Roanoke region. Thank you Dave for your years of commitment.

RARS Fest:

 Dee (KU4GC) requested and the Treasure approved expenditure to support 2 tables. This is a great opportunity to part with old equipment and purchase new, and add dollars to the club coffers.

Mission and Membership:

The OCRA club was established in the early 1990’s when life was technically simpler.  With the advent of competing technology provided by the Internet and cell phones, the role of amateur radio has changed.  This year, the Club is embarking on a discussion to revisit our Mission statement and discuss how we can enhance the Membership experience.

With the club beginning to age out, how do encourage new membership, increase active participation, and prepare for succession planning?  These are questions we seek answers to sustain trained hams for community service, promote the fraternal aspects of radio, and encourage technical outreach.

During this Membership meeting, many people raised questions, voiced concerns, and offer suggestions to improve club participation and amateur radio awareness in the area.  We truly appreciate the engagement and discussion.  Below are some of the salient points that were raised and will be discussed in future meetings.

  • The role of ARES and Auxiliary Communication has changed over the past several decades with increased consolidation and redundant infrastructure. What and how can we leverage these roles in OCRA?
  • How do we foster more relevancy with newer hams?
  • Chatham County Emergency Management has expressed interest in establishing an amateur radio CERT team. The 442.15 repeater is ideally located to support this effort.
  • Increase “hands on” programming to learn about lightning surge suppression, antenna building, and grounding.
  • Show and Tell makes for good programming. We have many DIY hams that engage in educational and fun development projects, which make for a good program.
  • Explore amateur radio in local high schools as an introduction during a class room and/or sustained activity with a station.
  • Establish a group build activity (QST project) where hams meet for a day or two to construct an antenna, or create various types of feedline.
  • Cross pollenate amateur radio with other local groups or clubs, like Linux club. Many hams use Linux in the shack.  Perhaps this becomes a cooperative topic for those interested in combining amateur radio with computers.
  • Park the MCU at a mall for a day. This would provide us an educational opportunity to demonstrate and discuss the continuum of amateur radio activities like satellites, repeaters, DX, etc.
  • Establish a bi-monthly agenda that repeats each year. The 5-6 agendas would be an annual topic .

What other ideas do you have?  Please be sure to “reply” to this post.  We look forward to hearing from you!

OCRA Board Meeting, January 28, 2018

Attendance:

Steve (W3AHL), Lad (W4ORD), Dave (W4SAR), Karen (KD4YJZ), Dan (KR4UB), Wilson (W4BOH), Keith (W1KES)

Topics:

  • Thanks to Wilson for hosting the meeting at his home.
  • Keith will reach out to Chapel Hill High School to explore the possibility of introducing students to the hobby.

Treasury

73 membership dues are current and an appropriate reserve balance is in our accounts.

For 2017 our expenditures exceeded income by $457. The largest contributor to our negative balance was the purchase of the extra repeater, which was a great value for the price.

Repeater

The 442.150 MHz repeater currently has limited usage. Steve (W3AHL) mentioned that resident’s of Chatham county would be interested in establishing a local CERT. The Board would support the usage of the repeater for CERT and encourage the residents to focus on developing the team. Similarly, the Board encourages OCRA members to join and support ARES, which is a great way for new hams to become familiar with equipment and techniques.

What questions, technical or procedural, would you like answered? Let us know.

OCRA Membership Meeting, January 8, 2018

Introductions:

Treasurer:

  • 71 membership dues are current and an appropriate reserve balance is in our accounts
  • Individual OCRA members supported the Bouvet DXpedition with $210 dollars’ worth of donations. The Board agreed to match individual donations up to $200, thus total contributions from OCRA for the DXpedition were $410.

Quick Notes:

  • First 2018 OCRA Membership meeting at Efland Baha’i Center went well. Membership agreed to continue using the facility for the remainder of the year.  Thanks to Dave, W4SAR, for managing the new location.
  • Dan, KR4UB, has made updates to the NCOCRA website. The goal of the updates are to improve the user experience, search ability, and navigation. Please let us know your thoughts on the changes and any suggestions for improvements in the “reply” section.
  • Steve (K1ZX) presented the FA-VA4 Vector Antenna Analyzer Kit from com. This low cost, $139 antenna analyzer powered by 2 x AA alkaline batteries, has graphing capabilities and provides one port measurement of frequencies ranging from 100 kHz to 100 MHz with a system impedance of 50 Ohms (BNC).  Good features at an affordable price….Thanks for sharing Steve.
  • Sherri Rapp, WB4OSU, recently purchased an Elecraft KX3, nice! As such, she is no longer in need of her Kenwood 440.  If interested please email Sherri at staleyrapp@mebtel.net or call her at 336.253.5549

Repeaters:

Dan, KR4UB, made large scale copies of the current Tower drawings.  He and Steve, KZ1X, will present the drawings to Tower Engineering in Raleigh to assist in the feasibility of putting the repeater on the air.

Christmas Dinner:

The 2017 Christmas Dinner held at the Hillsborough Exchange Club was well attended, and enjoyed by all.  Thanks to Lad for managing the details and for being a very gracious host.

Discussion regarding the 2018 Christmas Dinner entertained the idea of purchasing tickets in advance, rather than pay at the door.  This payment approach would better ensure an accurate head count and associated cost.  Further discussion will be occur later in the year.

 Field Day 2018:

There was much discussion on how to improve the Field Day experience.  Several notable discussion points included:

  • Establishing a food committee with dedicated resources responsible for suppling and preparing the meals.
  • Establish an operator schedule to ensure coverage of stations throughout the event.
  • Operational options ranging from antenna design and deployment to use of a bucket truck for adequate antenna height.
  • Sherri, WB4OSU, and Loren, KV4ZR offered to assist Lad on the food committee.

These discussion points as well as others will continue to be debated and discussed at future Board and Membership meetings as we get closer to the 2018 Field Day, June 23-24.

Membership Meeting Improvements:

Steve, KZ1X, suggested leveraging the large screen TV and wireless access for displaying content, like documents and videos, focusing on “how to” programs.  Wilson, W4BOH, also mentioned that there is good amateur radio content on the Internet that we can use in developing membership programming.

This new program approach may provide new Hams an opportunity to explore and learn about the hobby, while providing experience Hams an opportunity to share their experiences, best practices, and lessons learned.

If you have additional ideas or suggestions on how to improve the membership meeting experience, please reply below.

 

NCOCRA Membership Meeting, November 13, 2017

Introductions

Treasurer:

73 membership dues are current and an appropriate reserve balance is in our accounts

NCOCRA Annual Christmas Dinner:

The OCRA Annual Christmas dinner will be held this year at the Hillsborough Exchange Club on Monday, December 11, at 6:00 PM. We are striving to have attendance be above 60, which will secure the cost at $20 per person. Reservations for attendance are required no later than December 4th. Please email Lad (W4ORD) via the Yahoo reflector reserve your reservations.

Repeater Manager:

Danny Hampton made the Club aware that our current Kenwood TKR repeater series is being discontinued. As such, Dave (W4SAR), club president, made an executive decision to purchase an extra repeater as a spare.

The new backup repeater is identical to the one currently in operation.  This particular model is now discontinued, thus the urgency to purchase.  The new repeater was $1,000 and can be cloned to provide additional continuity for the existing repeater for many years.

For comparison, a newer repeater model is roughly $4000.  While the new repeaters are both digital and analogue, the additional cost would not have provided an identical clone to the existing repeater.  With the cost of tower work now around $1,000 per incident, cloning the existing repeater and having a ready backup made better fiscal sense than purchasing a newer repeater model.

Elmering or mentoring has long been the backbone of Amateur Radio. While technology constantly evolves, the human interaction between hams will not be replaced and will always remain one of the hobby’s strongest traditions. As such, there is a need to begin Elmering the next generation of FM repeater managers.  Understanding repeaters is a valuable skill for any ham, and especially for those ham’s interested in emergency response.

Please let Dan (KR4UB) or Steve (W3HAL) know of your interest to learn about repeater management.

ARES:

Public Service: AUX Comm site is down. Work is in progress to restore.

ARES Portable Station Equipment, Steve (W3AHL)

Many ARES/AUXCOMM events are best supported using a portable radio station.

“Portable” is defined here as:

Capable of being set up inside a building, such as a shelter.

  1. Twenty+ watts of output power.
  2. Antenna, mast and coax that allows placing the antenna outside, if necessary.
  3. Battery back-up capacity for 12 hours of heavy usage.

Often your mobile radio and antenna can serve as your portable go-kit (if easily removed from the car) by adding a battery, coax and mast.   An HT is not recommended as a primary portable station, although with an exterior gain antenna and a 12 VDC 7 AH battery, it may be sufficient for many locations.

Almost any VHF or UHF transceiver is suitable for portable operation.  A dual-band radio is desirable, but lacking that you may be able to use an HT or another single band radio to monitor activity on other nets.  The radio should be programmed with all of the frequencies in the ARES Communication Plan.  It should be used weekly or monthly to verify it is working.

Many ARES operators build a radio go-kit containing the radio, power supply, speaker, microphone, headphones, power/SWR meter and battery voltage meter permanently mounted in a self-contained box that may be weatherproof when closed.   Others keep their gear in a duffel bag, tote container, or just remove their mobile equipment when needed for portable operation.

Don’t forget to include “office supplies” like pens, note pads, ICS-213 General Message forms, stapler, tape, a small All-In-One printer/copier/scanner, etc.

Choosing the correct portable antenna system may be the most important decision in assembling your go-kit.  If local repeaters are off the air due to a storm and more distant repeaters or simplex operation is needed, your normal antenna may not be adequate.

We try to deploy in teams of 2 if enough volunteers are available.  That allows pooling of resources if one operator is missing some items needed for the site.

Some factors to consider are:

1.     Many commercial buildings will attenuate your signal and require using either an external antenna or one mounted near a window facing the required direction.

2.    A dual-band base, mobile or j-pole antenna that can be mounted on 15 feet of mast, with 75+ feet of coax is recommended.  A chart at the end compares the relative signal strength of typical antennas at various heights.  A 5’ base antenna mounted 15’ high will have 12 dB more gain than a mag-mount antenna on your car.  This is the equivalent of increasing your transmit power from 20 watts to almost 300 watts, without using more battery power.

3.   The mast can be a commercial push-up pole, 1.25” TV mast in 5’ sections or military surplus mast.  Fifteen feet is a good height that can be supported without guy wires and improves the antenna gain by 3-5 dB compared to 5’ height, or much more if it clears nearby obstructions.

4.   You should try to have several options for supporting the mast.  A tire board is good if open parking is near your operating position, which is often not the case.  A 3’ roof tripod can be used with a tire board, 12” long spikes driven into the ground, or with large rocks or cement blocks.   If guy wires are used to support the mast, they must be well-marked to avoid injury to pedestrians and cars.  This is often impractical, especially at night.  Chemical or LED battery powered light sticks on guy lines are a must.  Make sure they last all night.

5.    Coax and power cables must be routed to eliminate any hazards to foot traffic.  Red duct tape can secure it across aisles, but may leave a residue that is hard to remove.  White gaffers tape is a better option.  RG-8X coax can often be routed under a door threshold or window seal, but has 8 dB loss at 440 MHz per 100’.   Several shorter pieces of coax will allow you to use only what you need and reduce loss. Larger low-loss coax such as 9913F or Davis Bury-FLEX work well for long runs and only have 2.5 dB loss. Use a short piece of RG-8X to go under a tight door if needed.  Waterproof your connections.

6.   A simple power/SWR meter should be used to check your antenna & feed line before operating.  It’s better to find a shorted or open coax with a meter than by smelling smoke from your radio.

7.   Headphones are a must!  You will be able to hear messages more clearly and those sharing the space will appreciate the silence.

8.    Always carry a charged battery that will allow at least 12 hours of operation, assuming you will be transmitting 20% of that time typically.  An 80 amp-hour battery is rated to provide 4 amps for 20 hours, but your radio may not operate below 11.2 volts, so you may only get 12-15 hours instead of 20.  And batteries that are old, too cold or have been over-discharged may provide only a fraction of their rated power.   Carry a spare and learn how to load test a battery.

9.   The battery cables must be fused near the battery.  If the battery is connected to a power supply, use dual diodes to isolate them (or a West Mountain PowerGate), or you may fry the power supply when you lose AC power.   Battery terminals should be insulated to prevent accidental shorting.  Looded-cell batteries should always be in a battery case to prevent acid leakage during charging.

10. Use Anderson PowerPole connectors on all power cables.  Borrow a PowerPole crimper to make your cables. Don’t use a single-dimple crimper if you want reliable connections.

11. If your antenna is inside the building you may desensitize other agency’s radios or interfere with public address systems.

12. Frequently check your antenna, mast, coax and power for safety issues.   Don’t allow your station to become part of the emergency!

13. Once you get your portable go-kit packed up, actually use it occasionally, even if it is just in your back yard during the Saturday ARES Training Net.

Bouvet Dxpedition:

OCRA and the DFMA are trying to raise money for the January 2018 Bouvet Island Dxpedition. Both clubs will each match donations up to a total of $200. While cash and Paypal are acceptable forms of payment, checks are preferred. Please make the check out to Bouvet Dxpedition and add OCRA or DFMA in the check comment section. Additional donations can be made on the Bouvet Dxpedition website.

Field Day:

The joint field day operation for OCRA and DFMA has ranked 3rd again nationally. Second place went to W4IY, who had 1200 points on us. Please visit the ARRL Field Day results for more information.

Great Job Team!

We will begin focusing our 2018 Field Day efforts in January. Have a Great Holiday Season.

OCRA Board Meeting – October 30, 2017

OCRA Board Meeting

Attendees:

Dan (KR4UB), Mike (KK4BPH), Dave (W4SAR), Karen (KD4YJZ), Sherri (WB4OSU), Lad (W4ORD), and Keith (W1KES)

Topics:

Treasure Report: 73 membership dues are current and an appropriate reserve balance is in our accounts

UNC Repeater

Dan mentioned that Steve has worked with Tower Engineering Group.  Dan and Steve will request a quote from Tower to finalize the repeater drawings, and install the repeater.  Dan and Steve will bring the quote back to the Board for discussion.

Back Up Repeater

Dave made an executive decisions to purchase a backup repeater, after consulting with the Board. The new backup repeater is identical to the one currently in operation.  This particular model is now discontinued, thus the urgency to purchase.  The new repeater was $1,000 and can be cloned to provide additional continuity for the existing repeater for many years.

For comparison, a newer repeater model is roughly $4000.  While the new repeaters are both digital and analogue, the additional cost would not have provided an identical clone to the existing repeater.  With the cost of tower work now around $1,000 per incident, cloning the existing repeater and having a ready backup made better fiscal sense than purchasing a newer repeater model.

OCRA Christmas Dinner

The OCRA Christmas Dinner will be held again at the Hillsborough Exchange Club on Monday, December 11.  The goal is to secure 60 attendees, which will keep the cost below $20 per person.  The Board discussed having attendees pay in advance to ensure we reach a commitment level that is cost affordable.  Please consider securing your reservation by making payment at the November 13, OCRA Membership meeting.  We will also make payment available via PayPal.  We will discuss this topic more at the November 13 OCRA Membership meeting.

Field Day results – still not known.

Hopefully, we should know by the November 13 meeting.  Additionally, the Board discussed establishing a food committee for this year’s Field Day.  We need dedicated resources that are not operating the stations to secure the food and prepare the meals. This topic will be discussed more in early 2018.

Bouvet DXpedition

The Board discussed sponsoring the Bouvet DXpedition.  However, with the DFMA club already supporting the DXpedition, and with many members having dual membership in both OCRA and DFMA, the Board decided to encourage members of both groups to either support the DFMA sponsorship, or donate individually.
