September 18 7PM - OVARC Membership Meeting - via Zoom

Our guest speaker last month: Carl, KB7AZ.

On January 1, 1998, the FCC rules required that all amateur radio stations evaluate exposure to RF radiation. FCC is in the process of amending this requirement that was scheduled to be implemented in June of this year. The implementation date has been pushed back, but it is a good idea for everyone to conduct a survey of their stations. Carl's presentation showed the most likely rules update, along with an easy-to-follow process for complying with the upcoming requirement. You don't have to send your analysis report in, but you should have one in case the FCC or other governing authority asks to see it. To see Carl's PDF from the meeting, click HERE.

VP8PJ DX-pedition to Signy Island, Antarctica


What’s it like to board the Braveheart at Punta Arenas, Chile and sail for 6 days to 60 degrees south? What approvals are needed to land on an Antarctic island, ferry thousands of pounds of equipment to the island, establish a campsite and operate radio for 2 weeks, non-stop? How is equipment taken to the campsite, install tents capable of withstanding Antarctic winds, rain, snow and ice? What radios, amplifiers and antennas were used? Where did they get electrical power, food, and water? How many contacts did they make to how many countries and to how many different call signs?


In our July OVARC member meeting via Zoom, Gene - K5GS explained the answers!


June 27th-28th: ARRL Field Day - Update

From Tom Kravec W8TK, Field Day Chairman, updated 29 June 2020:

This year, Class 1D (home station on commercial power) were allowed to contact another Class 1D station for score credit.  


Several OVARC members petitioned ARRL to publish aggregate club scores this year. Though they do so for other contests, ARRL initially refused, but our campaign succeeded so the club gets credit for every contact made by members at home.


This is good news! Make sure that when you submit your FD summary to ARRL, you put Oro Valley Amateur Radio Club on the line requesting club affiliation. Disregard the instruction that club membership counts only for class A and F stations.




I encouraged OVARC members to get on the air on FD (June 27-28) as sole operators, thus continuing the practice of "social distancing". You would have use your own call, but be sure to include OVARC as your club on the FD summary sheet you submit. I suggested to the Coconino club that the trophy should go to the club with the greatest number of individual operations submitting logs to ARRL.


FIELD DAY 2020 PRELIMINARY RESULTS from W8TK, Field Day Chairman

Preliminary report of OVARC member activity is linked below. Names are in alphabetical  order, sorted by last names. If you participated but you don't find your name and callsign listed, please e-mail me with your name, call, and number of contacts made, at:

OVARC 2020 Field Day - Preliminary QSO Report Link


I count reports from 44 members. Many members had never or seldom been on the air before. That's what Field Day is all about! I have received only positive feedback from members. Perhaps this is the new paradigm for Field Day, and we need to debate whether or not to return to old-school FD in the future should that option become available...


Congratulations to all who participated. Great job!

June 19th 7PM - OVARC Membership Meeting -
via Zoom



In previous years our June Member Meeting typically had some commentary about Hamvention which occurs every year in May.

Of course, Hamvention did not happen this year. Not only were hams disappointed but vendors were disappointed as they had no audience to show their latest and greatest ham radio gadgets.


In checking with some of the Hamvention organizers, I reached out to a couple of vendors that would have normally attended to see if they would like to have some OVARC “air-time”. As I suspected, they were delighted with the opportunity to tell OVARC about their latest offerings.


So at the June 19th OVARC ZOOM Member Meeting we had a Mini-Vendor Night. We “staged” 4 vendors to give us all a pitch. I agreed to allow them to promote any and all things that they offer pertaining to amateur radio. The following vendors agreed to participate:


- West Mountain Radio

- DX Engineering

- Northwest Digital

- Flex Radio Systems


It was an informative meeting.

Norman, VK6GOM, Live from Australia via Zoom


Our feature presenter for our May meeting was Norman VK6GOM. Coming to us via a Zoom connection, Norman is located over 8,000 miles always in Busselton, Western Australia. 


Over the years Norman has looked into one of the many benefits of Amateur Radio, that being our cognition and how our hobby positively impacts our cognitive skills. Norm also told us about ham radio operations in Australia and a bit about the activities in his a local club, the Bunbury Amateur Radio Club. 


It was very informative to learn more about this little-known benefit of Amateur Radio.

6 PM Pre-Meeting Friday February 21, 2020

(Prior to the Regular 7 PM Meeting)

Have you been on FM since man created handheld radios? Are you wondering, "how do I get on Fusion?" Buying a radio is the easy part; how do I get on Fusion once I have it in my hand? What’s the attraction for getting a HotSpot? Do I need one? Can I get on Fusion without one? How do the OVARC repeaters fit into all of this? What about APRS? Should I throw away my FM handheld radio?

If you had questions that are close to these, then you should have come early to the Friday OVARC meeting on February 21st. Mike, K7VTT answered “Fusion Questions”.

Notable Antenna Designer Presented at the February Meeting

At our February 21st meeting, Tom Schiller, N6BT, talked about antennas. Tom is the founder and owner of Next Generation Antennas. He designed the Force-12 antennas and authored a great antenna book titled “Array of Light.” He still holds a few world records, including the 160-meter CQWW QRP CW in 2007, and the 80-meter CQWW QRP CW in 2003. Those records still stand today. Today he lives in Kingman Arizona on several acres of land as he continues developing new antenna designs.

Tom covered antennas for smaller spaces, taking into consideration the bands desired, operating interests, budget, restrictions, etc. He also included his research on verticals and other antennas that he has done over the past several years. Subjects included take-off angles, efficiency, balanced current, baluns, "radials vs. counterpoise" (including his present Vertical Open Ring system) and his article in the May/June 2019 National Contest Journal (NCJ).

Afterward, Tom was glad to take all questions. Having shipped over 26,000 antennas and a product line of close to 200 models, he has probably tried and built most everything, including aluminum towers, masts, and tower trailers. For DX enthusiasts, he can provide insight from The Team Vertical contest team, and many other DXpeditions.

Gary-AE7GP, Fred-W2HZ and Hanna-KG7TPD have accepted nominations to run again for another 2 year term. (Note: They were all re-elected). 


This leaves two Directors who will retire from the Board: Carl-KB7AZ and Ross-K4WBR. Many thanks to Ross and Carl for their dedication and commitment to OVARC during their term.


The nomination period for the 2020 elections is now closed and there are two nominations to fill the two upcoming vacant seats. Those nominees are Hal-N7BAZ and Logan-KE7AZ. (NOTE: All Board nominees were elected).


Slow Scan TV (SSTV)

Presented by: Carl Foster - KB7AZ


Slow Scan Television (SSTV) is a picture transmission of still pictures via amateur radio. It is inexpensive and used by many amateurs as well as our International Space Station (ISS) crew. 


Our own Carl Foster – KB7AZ presented Slow Scan Television for Amateur Radio. He answered questions about clarity, speed, signal width, etc. in detail.


Carl, KB7AZ, was first licensed in 1970 and has worked as an RF design engineer from 1973 until he retired from Raytheon in 2011. He currently holds an Extra Class license. Carl's amateur radio interests include HF, VHF, DX, RTTY, SSTV, public service, and antenna design. Carl was one of the designers of the first digitally synthesized amateur transceiver, the Astro 200, which was sold from 1977 - 1980. Since then he has worked in aerospace data links including message protocols, telemetry, range tracking, and range safety. He is the current ARRL Arizona Section Technical Coordinator and previously served as an OVARC board member and the club's Secretary.
