It's a strange bug(?) for sure.? I repeated my headphone versus pc soundcard input test again this evening and the sidetone audio was perfect using both!?? I definitely had the problem before but

Hans, I just went back and checked. The clicks were there as far back as 004 (Rev1 PCB). However they didn't become nearly as obvious until ver 012 when the volume control was fixed. But the max gain

It goes back at least as far as 10, which was the firmware on my first delivered QMX. It’s noticeable in headphones and amplified external speakers and in RF and practice mode, into a 50ohm load and

Good morning is there anyone using an n7dcc atu10 (Chinese copy) that has a jack on the back labeled ext. is that external power to charge the internal batteries? if so what type of plug does it

Evan, Really appreciate your help and info. Will try again to make sure toroids are good and check the diode voltages. One problem I have is identifying? right solder point on bottom side of

I had the same issue for a while. I tried snap-on ferrites on everything, but that didn't help in my case. I finally made a proper choke with 14 turns of coax on a ft-220-43 -- Nipped it in the bud

14 I think. Whichever was the first one released to try and fix the other keying issues.

Personally I think that maybe the volume should be slowly increased from zero instead of just switching on and off. Also, I will say that although the thump isn't as bad during normal operation, it's

I wonder if this was ever tried? ... i.e. "increasing the Tx/Rx turnaround latency" to eliminate the clicking/yhumping sounds? It may be quiet but I don't agree that it's unnoticeable.

Does anyone know what firmware version this started in? 73 Hans G0UPL http://qrp-labs.com https://buymeacoffee.com/g0upl

Looks like a lot of consistency in the settings being reported. Mine probably won't add much, but I promised to post them. I did try this in Practice mode, which I had not used before, and the clicks

Try transmitting into a dummy load and report back if this changes the disconnect on TX issue.. What kind of antenna are you using?? End-fed antennas have a RF-in-the-shack reputation. 73, Don

I use 70db slope, 50 smooth samples and 15dB/s of recovery. That AGC works great for me! Thanks a lot @Hans, what's next? :D

Thanks :)? Maybe I'll customize it with a stencil of a old style ship or something in the end, we'll see!? Digikey parts should arrive tomorrow according to Fedex, in theory, so I'll hopefully know

the laptop is mounted into the lid of the case by using some short alu profiles ... so I have a all-in-one ... may you can try your own ideas

Dbl.click 300 - no reaction, 500 - works after 3-5 attempts, 600 - switch RIT on immediately. It was not so before, 300 was OK. 73 Igor oh2jxa

Chris, I think it still comes back to volume level. I tried using my little amplified speaker and the clicks are gone - that is until you turn the volume up to really uncomfortable levels - then they
