QMX thumping issues on CW

[@AnthonyJones-vk6xq]

60m and 40m i could just about live with, as for 80m 30m and 20m thats a different story. Love your 9A5N key, very very nice. Best 73.

I have the high band - same issue, but different affected bands. Glad to see it’s not just me! Fingers crossed Hans can figure it out. He’s a wizard.

Do you have AGC enabled? Also, firmware version 19 came out recently and has an option to turn off thumping.

[@AE5X]

Yes, shortly after this video FW .019 fixed the problem.

I would how some people would do back in old days of cw when you had to have a sounder

My thumping seems to be about the same on all bands. I am using an amplified speaker (a ball sized one slightly smaller than a tennis ball). What AGC setting seems to help? I think for CW I could easily use no AGC because the band noise is not amplified with no signal (and less fatiguing) but a signal seems to pop out of the noise better.

I can hear what you are talking about. I have this radio but haven’t had a chance to try it yet. 40m is my favorite band with 20m and 30m being my next favorites. I doubt this issue will be a problem for me as such. I’ll be interested to see if this problem can be resolved. Great job on the video…72!

I'm not sure if each QMX displays the same behavior on the same bands. 80m seems to be commonly affected but others report significant thumping on 60 and 40 - I don't have a problem there. I have tried a few AGC setting that were suggested - they don't seem to make much difference. AGC settings in this rig are infinitely configurable - may too much! I'm lucky in that the most affected band on my QMX is a band I never use. Good luck and 72, John

Never really noticed on mine.
