It appears the problem is more deep-seated. I’m away /P right now and decided to do some FT8 using a Raspberry Pi. I set up the Tx drive (seemingly) OK, by pressing Tune on WSJT-X and adjusting Tx level and Mic gain to get the right amount of ALC. However, when I then try to Tx again, TX LED lights but there is no drive. A Very slight nudge of the MIC gain causes 5-bars on the display, but next time I Tx it’s back to no drive.
Has anybody else experienced this?

This last week I’ve been doing some SOTA activations, so I’ve been using my KX2 instead. I noticed a couple of issues when setting the Mic gain. I followed the advised procedure and reduced PWR=0, TX CMP=0, squeezed the PTT and spoke normally into the MH3. I found that there was no indication at all on the ALC meter until at about MIC=65, ALC jumped to 6-7. Mic bias is on. I also noticed on a few occasions that when operating, pressing PTT had no effect until I slightly increased the MIC gain. The MH3 works fine on my KX3, so I’m assuming the MH3 is OK, but I can’t figure where the problem lies. 73 Gareth – M5KVK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
