Video: TR-35 in the CWT Sprint

I really get into these sprints sometimes, but not today. Just wanted to use the traffic they generate to show you the new kit/rig in action.

The TR-35 was keyed with N3FJP logging software specifically for the CWT Sprint. I checked briefly for contest activity on 40m but it's too early yet. The rig's display doesn't really fluctuate as the video would seem to indicate - that's just some camera artifact.

5 watts, dipole, LiFePO4 batt'reh.

Just a quickie:

  1. Nice! I like the center-off momentary switches. I used those many years ago when I designed a micro-controlled frequency doodad to drive my Icom 22S, so I could use frequencies that weren't in the 22-channel diode matrix. It worked a peach, but was soon obsoleted by Michigan moving to 20 kHz repeater slots, instead of the 15 kHz reverse/split-split that was popular elsewhere. The final nail in the coffin was the opening of the 145 MHz band for repeaters. The IC-22S synthesizer only stepped every 15 KHz, and didn't lock up much below 145.5 MHz, so I let it go at Dayton for a song. I gave all the schematics and a software listing for the MC6802 I had used to the buyer. Someone had urged me to write it up for QST, but I figured it was obsolete already, so no one would be interested.

    It was fun listening to you working contacts in the Sprint.

    1. Hi Dave, I've often wondered how many projects in QST or other ham magazines actually get built by those who read about them. I think a lot of their appeal is enjoyed mostly by "armchair constructionists" for lack of a better term. I've read lots of articles and thought, "It would be cool to build that" - and that's as far as it got. I'm betting I have plenty of company...

      My enjoyment of kits comes from the fact that they circumvent the problems of parts procurement and circuit board manufacturing - the main reason I don't follow through on construction articles. But I do like to read them.

      Obsolete or not, I'll bet the article would have been read by many.
