OCRA Membership Meeting, September 10, 2018

Introductions:

Sixteen members were present, with three people taking exams.

Treasurer Report:

Balance continues to be strong.  Currrent membership is at 78, with 23 needing renewal, and one expiring this month.

Seventeen new members have joined since January.

Repeater:

Dan (KR4UB) brought the latest Southeastern Repeater Association (SERA) repeater journal, providing a listing of repeater frequencies and other relevant information. The SERA was founded in 1971 as the North Carolina FM Repeater Association Inc., when a group of state repeater owners got together to form an organization designed to assist in coordinating, providing communication & technical information, and bringing together all amateur repeater owners into one united body.

RepeaterBook applications are available for Android and Apple devices.  The applications are helpful to identify local repeaters during travels.

Have another Meal (HAM)

Wilson (W4BOH) has offered to host a family friendly, fall cookout of burgers and dogs in October.  You should have received an email via the group.io list serve.  If you did not receive an email, but are interested in attending, please let Wilson known. Please bring vegetables and desserts to share.

Green Bank Telescope

Dan (KR4UB) is planning to revisit the Robert C Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia.  The Green Bank site was part of the National Radio Astronomy Observatory (NRAO) until September 30, 2016. Since October 1, 2016, the telescope has been operated by the newly separated Green Bank Observatory. The telescope honors the name of the late Senator Robert C. Byrd who represented West Virginia and who pushed the funding of the telescope through Congress.

The Green Bank Telescope operates at meter to millimeter wavelengths. Its 100-meter diameter collecting area, unblocked aperture, and good surface accuracy provide superb sensitivity across the telescope’s full 0.1–116 GHz operating range. The GBT is fully steerable, and 85% of the entire local celestial hemisphere is accessible. It is used for astronomy about 6500 hours every year, with 2000–3000 hours per year going to high-frequency science.

Amateur Radio Emergency Service (ARES):

ARES:

Steve (W3HAL) stated OC Emergency Services has requested that OC ARES/AUXCOMM volunteers be on standby for probable activation to support evacuation shelters due to forecasted flooding, high winds and power outages. Details are pending updates on Hurricane Florence’s path and timing and probably won’t be available until late Wednesday or Thursday morning.

The typical scenario would have one or two shelters plus the EOC opening, with a team of two ham radio operators per site for two 12 hour shifts per day.  That would require 12 volunteers each day.

As always, the first priority is to make sure your family is safe and prepared for the storm, as mentioned on Saturday’s ARES Training net.  Meanwhile, evaluate your availability to deploy on Thursday, 09/13 through Saturday, 09/15.  If you think you might be available, depending, on how the storm actually affects our area of course, please email me directly so I can get a rough idea of how many volunteers might be available.

Volunteers would need to be registered in the AUXCOMM database to deploy to the EOC.  For shelters, at least one on the team would need AUXCOMM registration and the second could be an ARES volunteer.

And one final reminder to log into the AUXCOMM database and verify your contact info is still valid, if you haven’t done so recently.   https://www.auxcomm.us/db/nc/  (Ignore the certificate error notice)

Please contact Steve w3ahl@att.net for further information

Hog Day:

Hillsborough Hog Day may be postponed or cancelled due to Florence.  Please check the website for up-to-date information.

Boy Scouts Jamboree:

Jamboree-on-the-Air, or JOTA, is the largest Scouting event in the world. It is held annually the third full weekend in October. JOTA uses amateur radio to link Scouts and hams around the world, around the nation, and in your own community. This jamboree requires no travel, other than to a nearby amateur radio operators ham shack. Many times you can find the hams will come to you by setting up a station at your Scout camporee, at the park down the block, or perhaps at a ham shack already set up at your council’s camp.

Martin (KA5JUJ) shared how one creates a cantenna, a tin can waveguide for WiFi.

Baofeng handheld radios are popular in the amateur radio community as inexpensive, entry level HTs.  Future OCRA membership programs including learning more about repeater operations, programming a Baofeng, and overcoming “mic fright.”

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/DFMA Groups.io Photo Upload Procedure

A new Photo section has been recently activated for all subscribers to OCRA-DFMA@groups.io.

If you haven’t tried it yet and have some good Field Day or other amateur radio event photos, here is a demonstration of the procedure.

If you are logged in to groups.io, this link  https://groups.io/g/OCRA-DFMA/photos will take you direct to the OCRA/DFMA groups.io photos gallery.

Or, from the groups.io home page click on the   tab to go to the photos home page. You will see several albums already on the site e.g. 2018 OCRA/DFMA Field Day, 2018 Field Day Potluck, and others.

You can create a new album by clicking on the blue New Album tab  or you can click on an existing album to add your photos.

A couple of thoughts about opening new albums:

  • The reason the “2018….. ” albums shown above are listed first is that the site lists albums in alphabetical order.
  • If you do choose to open another album the name ought to start off with consistent naming with the albums already in existence, otherwise the albums for the same event will be scatttered though out the whole library of photo albums.
  • Lastly, you might want to consider adding your photos to an already existing album to avoid viewers having to open many different albums to see all the photos related to a specific event. Each photo within an album will show and give credit to who uploaded the photo to the album.

To select an existing album, click on the photo
