Here's my observations on a QMX Rev 1 (80m-20m) and 1_00_017 firmware:
I keep AGC enabled. I no longer hear the old objectionable thumps I used to hear at the end of a dit or dah.? I do hear key clicks at the beginning and end of a dit or dah. They are not very objectionable but they are there.? The clicks appear louder when I'm on 40 meters with its normal background noise. The clicks are not as loud when I'm on a quiet band (I saw this on 20 meters.)? So the amplitude of the clicks seems to be somewhat a function of the background noise with AGC enabled.? In practice mode, I still hear the clicks, similar to how they sounded on 40 meters.? FWIW, here's my settings:
Audio:
atten = 0dB.
Mute at min volume: No
AGC: On
CW offset: 700
Sidetone freq: 700
Sidetone vol: 83
Sidetone rel/absolute: absolute
Keyer set to semi-break-in though this is not coded yet.
AGC settings:?

Hello Daimon
There are a lot of people using it WITHOUT these issues with key-clicks. So there's a bit of a mystery here. Could someone happy with QMX performance on CW without key-clicks please post your settings here? Sidetone settings?(level, absolute/relative) and AGC settings. Then if Daimon you can post your settings too, we could compare and perhaps more easily find the culprit.?
There could also be a possibility of a hardware problem on your particular unit. Do you see any errors reported on the Diagnostics screen? Anything is red coloured?
Hi Hans,
My QMX is a year old in two months time, and for most of that time it has been unusable on CW for my style of operating (extra dits and dahs mainly the issue, as I am mostly a 20-25 wpm op.)
Thankfully FW 17 fixed that but now we have the key clicks. I had a QSO on it the other night, but after 20 minutes I had to switch rigs to an old vintage Shimizu as the clicks gave me a real headache and made it hard to concentrate on the sidetone. The rig has sadly had to be consigned back to the drawer it has spent most of its life in. (Note: I have played with AGC settings as mentioned on other threads - they helped a bit but it is too still intrusive to be usable.)
I do not underestimate the scale of the challenge and complexity of this rig, or of how busy you are with other work too, but is the light close to the end of the tunnel yet for CW please? I want to like the rig, but so far it has just not been usable in any meaningful way on CW. Many of the updates have been bug fixes or additional new features, rather than getting this core CW functionality right.
Please take this in the spirit it is intended - I am a fan, but am losing faith with this particular product. I hope we are close to a resolution.
Thanks,
Daimon. G4USI
