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

Re: QMX (20-10, 1_00_017 fw) RIT dissapeared
Dbl.click 300 - no reaction, 500 - works after 3-5 attempts, 600 - switch RIT on immediately. It was not so before, 300 was OK.

Re: QMX - Any progress on key clicks please?
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

Re: QMX - Any progress on key clicks please?
Chris,
I tried your settings and there is no change. Unless... you turn the volume way down. Volume level is the only thing that seems to make a difference. Low volumes, I don't hear clicks. High

Greg,? I think I also trimmed most of the tab off so it wouldn't interfere with other components.

Re: QDX - stops on 10m after a few seconds
Torsten,
RF getting into the USB cable?
Try different cables, put chokes on cables.
Or stop common-mode signals on the feeder. Reconfigure antenna.

Re: What Mods to Early Rev 1 QCX Mini
It's an easy mod. You just move the 7805 over to the left one pin and solder the left most pin to the bottom of the diode.

Re: What Mods to Early Rev 1 QCX Mini
Tnx all.? Not that I *plan* on shorting the 5VDC to ground, but replacing the regulator with a 78M05 is appealing.? Where will I find details on that fix?? Is it drop-in, or does it require some

Hello there :)

Re: QMX - Any progress on key clicks please?
I think the thumps are coming from the AGC and you disabled it. increasing sidetone volume to 60 also somehow helps.

Hello Emory,
12, 11, and 10 meters share the same low pass filter (LPF).? This would point to a problem there.? The most common is one of the toroid connections did not burn through the enamel.?
