2018 Field Day… 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, Field Day Planning, 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 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:
