Operating Notes: Youkits TJ5A problem, one good thing about a dead band

March 8, 2021 By Dan KB6NU Leave a Comment

Odd Youkits TJ5A problem

Yesterday, I worked a guy who was running a Youkits TJ5A. I had called CQ on 7028 kHz, but missed his first replay because he was 700 Hz off frequency. After I set the RIT to +700 Hz, we began the QSO. On my second transmission, I mentioned that he was off frequency. He said that yes, he realized that and that he was having some trouble with his rig, a Youkits TJ5A. He asked me to stand by while he did something to the radio. When came back, he was transmitting on frequency (7028 kHz), but he was also transmitting some kind of spurious signal on 7028.7 kHz. See the panadapter display at right.

I’d never seen anything like this before, and I’m wondering if any of you have. One thought that came to mind is that somehow the sidetone is modulating his CW signal. It’s hard to say, though, because I wasn’t able to find a schematic for the radio.

If any of you know where I might get one, please let me know. Also let me know if you might have some ideas about how to fix this problem.

One good thing about a dead band

Yesterday, I got on 30 meters in the afternoon. I didn’t expect much activity, and of course, there was very little due to the ARRL SSB DX Contest. For some reason, my fist just didn’t want to cooperate, and I made quite a few errors. Just for kicks, I tweeted, “One good thing about a band being dead is that no one hears it when you make a mistake calling CQ.”

My Twitter followers seemed to like it. That tweet got more replies than I’ve gotten in a while. :)
