Hi Peter, Thanks very much for the modification information. I'll watch and read up and if I feel it's doable with my modest abilities, I'll probably have a crack at it. I've had several WSPR

Hans, Forgive the resurrection of this thread, but, in beginning to sift through the parts of my QDX kit, I noted the cores designated for L2, L3, L4, L6, L8, and L10 were described as "37-10 toroid

Karl, there is another possibility but I never tried it myself as I am a huge CW-fan and dont want to loose the filter: https://www.maxwellmoran.com/qrp-labs-qcx-project With this Modifikation you

I've listened to this weekend contest in 20 and 40m bands and tinkered with AGC settings some more. I've also tried Paul (W9AC) suggestion to increase "Smooth samples", and it seems to alleviate the

Hans; Now I understand that the reason 5MHz band is still on the menu is to enable rx only, but no tx is allowed.? Many thanks!!

Hi Roy Thanks... I'll fix that. No problem. It's just that pesky AGC sample buffer again... It's in use all the time audio is running. When you go in and change the size while it's in use things can

Very pleased with the new features. The QMX is growing up now. Well done Hans! One thing for my wish list would be a variabel filter setting for CW. I'm working a lot of guys using homebrewed tx or

Hi Bruce, I'm getting nothing on 14.0971. However, as per Peter's suggestion, 14.0964 provided a few hits late yesterday evening. Hopefully, there'll be more today when the band wakes up. Karl

Thanks, Peter This generated a small number of hits late last night. I will try again later this morning when the 20M band is more lively. Karl Sent from Outlook for Android

Hans, Thanks so much for this, a great improvement on CW!? Paul, thanks for thes ettungs, I've been playing around with them a bit with QSOs on 30M and litening to the 'test on 40M.? Think I'll end

The DX contest is proving to be a great way to test the AGC. And it is working quite nicely.? Thanks, Hans! Just hopped on 20m and snagged two Spanish stations and a Hawaiian station. Amazing what 4W

Hans, FYI: I just tried to set Paul's "good start" settings (post below), not through Terminal, but through the QMX menu. After finishing, selecting the right push-button to step out, my QMX

See below.? The high "Smooth Samples" setting seems to eliminate much of the audio clicks.? The remaining settings give reasonably good dynamic range while limiting strong signals. I'm still

All I can say it’s a good thing I had lifted the leg of pin 32 of the cpu that was NG before I removed it. ?That saved me. Jeff W1NC

I loaded .17 and it is working well on digi with iFTx on the iphone. ?Thanks to Hans ill be trying it out on the next SOTA outing.?Jay KE7OT

Bill, you should also check for continuity from point 5 to point 8n to make sure they are connected perly via the circuit board at points 6 and 7. Should be OK to proceed. good luck ...

P.P.S. yeah there's a lot of clutter in there. Like my workbench (see attached)... the QMX "Lab" is almost as cluttered as the real one. 73 Hans
