The QCX-mini has a very sharp CW-filter with center at 700 Hz. Try tuning your QCX-mini at *14.0964* MHz. Then you can hear(!) WSPR. At oder versions of WSPR-software you can change the pitch so you

Hi Adrian, Danny, S-meter and AGC seem to work very well, however, as Danny noted, when I'll look into that. > I configured AGC with the values seen in your screen captures, they seem Yes I

Hello Bojan With the LPF sweep I suspect that the chosen output power is too much for Please could you explain? I didn't understand what you're getting at? > 73 Hans

Hi, Can someone please advise?? I want to use my 20M QCX Mini with TCXO to listen to WSPR using WSJTx. Do I set my receive frequency to 14.0956 MHz, or 14.0971MHz? My PC time is spot on, but I

Hans, thanks very much! S-meter and AGC seem to work very well, however, as Danny noted, when transmitting, some artefacts like static can be heard on each dah or dit. With AGC disabled, these are

S meter works well. With the LPF sweep I suspect that the chosen output power is too much for the LPF test as it is obvious that half of the sweep goes into the filtered zone. -- 73 Bojan S53DZ

Popped the new buck converter in, downloaded and dropped FW 1_00_017 and shazaam!

Hello Timo At the moment yes that's the design. The IQ mode abandons all subsequent audio processing after sending the audio to the PC. Including AGC. And yes I did enable AGC and S-meter only for CW

Well I loaded 1_00_017 (final "ripened" version) into my 12V rev1 QMX with a QRP Labs dummy load attached. Loading of the new version went fine. I immediately went to the AGC submenu and started

No issues? ? Hans,? .......? ?sweet as a nut!? ? ?:-)? ? ? ??

Well, after some sweating, I managed to talk to it after rebooting the PC as well as the QMX. I am back on version 16. I don't know whether I will ever have the nerve to try 17 again! Regards Bev

Thank You, Thank You, Thank You! Hans, you are the best. Mike Krieger

Personally I bought a Siglent SDS-1104XE which is a very capable 100mhz 4 channel unit. It’s has loads of features, an excellent display and is expandable to 200mhz. Very pleased with the purchase

OK! Glad that worked! A word of caution, though. Your power supply is pretty high for running a 12V QDX. You might want to bring it down a couple of volts, or perhaps two silicon diode drops in

That did the trick! I looked closely at the joints for L1 and L2 and noticed that one of L2's? pads (nearest IC3) wasn't fully flowed around the wire. It passed the continuity check when I assembled

Thank you Hans! I have been waiting for AGC to take this out on POTA again!!

So, got a QSO in the log and the good news is the AGC seems to largely work, particularly on Rx. However it has introduced a very sharp tick at the start of each dit and dah on Tx.? This is very

Hi Bev. See my notes in this thread on how to roll back to 016 (or whatever you were running before the update). You'll have to remove the 4 bottom screws (2 on each side) to pop the bottom cover

John The usual culprit causing no output on one band is a bad solder joint at one or more toroid leads in the LPF for that band. That is usually the result of inadequate enamel removal from the

Ok, forget my post, it was a bad contact in a BNC/PL adapter.
