What version of firmware? -mike/w1mt

The amp is (more ore less) working. Heap down your abuse upon me for my malignant deeds, of which I will speak of presently.... Center pin of q4 got disconnected from one of the resistors. Works

I have been using the QRPLabs dummy load connected to my QMX, with a Begali paddle, to practice my morse sending. The issue I have is a little random in that the length of time that things are ok

Thank you Hans… It will be very exciting when his radio can do sideband. i’m looking forward to it and I do know I have to be patient because you don’t release updates until you’re 99% certain

Can the choice be retained by mode??? CharlesK5KXJ

Glad you got it working Yuri. Best 73…Ron

May I caution here, digital modes are all USB so one does not want the lower bands to change to LSB. 73, Cliff, AE5ZA

Thank you Ron again! I checked output pins before soldering and no shorts or low resistance to ground. After that I soldered FST3253 from QRP-Labs and everything works like before. Only performed

Hello Howard Yes you are correct, at the moment there is only the one USB/LSB setting and it applies to the whole radio, not by band. I will fix it eventually, particularly when it comes to the

I have the QMX And I love this radio. The one thing I’m not certain if it has or has not been addressed is I love to listen to upper and lower side band audio on 40 m and 20 m. The only issue is 40

Sure Cliff, I tested the QMX both in WSPR independently without using software and in CW, I made a local QSO on 20 meters and the power output is 7 W, so there shouldn't be any problems, I'll have to

By software I was thinking of ones like fldigi that is used for digital modes as fldigi and some other digital mode software has difficulty with the QMX if Transmit ID is on. It will transmit once and

Hi Cliff, what do you mean what software do you broadcast with?? I simply updated the firmware and figured out the QMX with the wspr data. The first transmission went well, the subsequent ones

Thanks Adrian and Jim, Glad I am not the only one.? Being a CW wannabe, but no where close to actually using it effectively, the SDR functionality is quite important to me, and seriously, the QMX

What software are you using to transmit? Does it transmit in hardware test mode when in the config mode via putty? 73, Cliff, AE5ZA

I am NOT new to using hot air to solder SMT. However, removal is something I have only done a couple of times before, on boards that were less dense, hence the request for suggestions. I like the

Wonderful suggestions - I will check these this evening. T1 has been checked and double checked (and wound twice just for fun) so I don't suspect it. But the other parts deserve a triple check, and

Hello Timo, Most likely a bug, I can reproduce it on my QMX and at least one other fellow ham reported it couple of days ago. Enable IQ from the System config menu and it will

Hi Andy, Ron, Ron, good point to check the T/R switching, but check all switching diodes: the RX and TX. My 50W (QCX) PA is also built with the 20m LPF. I have just tried?quickly driving it with

likely causes.... D1 bad or backward. R2/3/4 in the wrong places or wrong values. or T1 has a shorted turn(s). I'll toss in soldering problems. Note: the 10W linear is not even close to the 50w in
