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.

Board of Directors Election

Friday January 17th 2020 was the regular OVARC Meeting. It was also our Annual Meeting and the meeting when we hold our elections.

 

In 2020, five director’s seats were up for election. Those directors are Gary-AE7GP, Fred-W2HZ, Carl-KB7AZ, Ross-K4WBR and Hanna-KG7TPD. 

 

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.
