Once again we meet via Zoom. This month Jess, W6CKC opened the meeting with club president Clark, K3NI. After introductions Bob, KI0G from his winter home in Moab, reported on how hams supported the Moab 240 Endurance Run, which is an annual meeting of insane people who attempt to run as fast as they can for 240 miles in less than 112 hours. These folks actually pay money to do this sort of thing. Then Clark updated the group on the status of the new Marble repeater link, which will add greatly to the range and reach of the ’88 repeaters. Yours truly gave a quick show-n-tell of my new station backup batteries, the Valence U1-12RT. These are pulls from medical equipment and have most of their life remaining.

Zoom video recording off Bob’s (KI0G) Field Day for noobs. Bob does an excellent job of explaining the mechanics of operating during the annual Field Day “not a contest.” Go out and get on the air, it’s a whole lot of fun and a great chance to get your feet wet.

New year, new venue! We met on 01/12 at the Glenwood Springs branch of the Garfield County library. Nice big room with (as we discovered at the end of the meeting) a PA system and high resolution projector.

Don Moore, W0CTX showed off his CommRadio CTX-10. And when I say “his radio” I mean it is actually a radio he designed and manufactures here in Colorado! The CTX-10 is a 10 Watt extremely portable 80-10 Meter all mode transceiver. Designed for simple operation, it includes an internal tuner, internal LiPO batteries (off the shelf 18650 cells), OLED display and only 8 controls. Don tells us the story of how he got into the radio business and his design goals.

If you’re not going to the ARRL Digital Communications Conference in Albuquerque, come out to the US Bank building in Glenwood Springs to see Bob Cutter’s (KI0G) demonstration of the “OG” digital mode, an antique spark gap transmitter.
From Wikipedia: Spark gap transmitters were the first devices to demonstrate practical radio transmission, and were the standard technology for the first three decades of radio (1887–1916). Later, more efficient transmitters were developed based on rotary machines like the high-speed Alexanderson alternators and the static Poulsen arc generators.[1]


Most operators, however, still preferred spark transmitters because of their uncomplicated design and because the carrier wave (carrier) stopped when the telegraph key was released, which let the operator “listen through” for a reply. With other types of transmitter, the carrier could not be controlled so easily, and they required elaborate measures to modulate the carrier and to prevent transmitter leakage from de-sensitizing the receiver.

 
Meeting starts at 10:00, runs until about noon or a little after. VE testing, show and tell, and general topics of interest to the club are invited.

Glad everyone enjoyed my presentation. Here are the pictures that Gerry, Brian, Pete and I took while flying. Word around the club is that Debbie N0LDB is going to get one for her birthday this year!

Ken, KB0HP gives an excellent talk and live demo of JT-65 weak signal mode and Bob K9MWM has a report from his and Sue’s (N0DBY) trip to Quartzite RV meeting and hamfest. As usual, sorry about the production quality, but I think I’m getting better at the one-man-band production system. This month I ditched Switcher Studio and tried out Rico Live multicam, which doesn’t do realtime streaming (which didn’t work all that well and gobbled up data), but does record all footage locally and render it later, which I think does a much nicer job.
