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

I have just completed and tested a QCX+ and I very pleased with it - a big thank you to Hans and the team. The kit is superb and the build was very enjoyable with excellent documentation and on-line

Andy, I tested my 20 Meter 50 watt PA using the NanoVNA and found approximately 2:1 all the way out past 50 MHz. I didn't check higher in frequency. When I unkeyed the amp, the SWR went to infinite

Timo - I am on version 16 and could not get IQ to stay on when I was turning it on in the Digi interface menu. However, when I turned it on from within the System config menu it stays on. That might

I installed software version 16 on the day it was released.? I use the "IQ mode enable" on HDSDR literally daily and was fine. Today, for some or other reason, I can set IQ mode to enabled, but as

Hans, Thank you for clarifying the operation of the band swap. 73, Steve W6WU

This isn't the first time this has come up here...I'm curious as well. I don't know much, but it is interesting to me/ I wonder why 1 uf caps are used on the input here. On the 10W linear PA kit, it

Hello Steve No. It swaps a band called "20" with a band called "80". It doesn't swap slots BPF 1 and 3. I am quite doubtful that this swap is necessary or beneficial if the proper Rev 2 mod is done
