This looks exactly like the issues that are discussed in /g/QRPLabs/topic/qmx_with_1000_tone_on_12m/110457498 I am surprised you can't hear the 1000 Hz tone when you are in CW mode

Hi all The ADC measurement voltage is multiplied in the code by 5.7 (due to the 10 / 47 potential divider). It IS expected that the TX voltage is less than the supply voltage because the code is

Jason I am interested in a printed version, but can't find your DM info. Please contact me at W3WJ@.... Thanks, Bill? W3WJ

I was experiencing many of the same problems discussed in this thread, so I've been following the advice that's been given.? ?My QMX+ and WSJT-x are now on good speaking terms!? CAT control

Thanks for the ideas so far. As I am used to Iambic A I also choose this option on the QMX. Incoming RF obviously is not the problem as this issue also occurs in practice mode. To be shure I tried a

Really liking my QMX+ too. There are still a few things I don't know how to do yet, but overall it is just what I wanted for my bedside station that I use before going to sleep. Worked Slovenia from

Sorry for OT. Hello Stan, thanks for your praise. But for me it's dangerous to believe in it. You only don't know when I was wrong :-). 73 Ludwig

I’ve had my QCX+ up and running for a couple of weeks now at home, and have made many QRP qso’s on it and a OCFD. ?I find the hobby so rewarding using a new language I learned recently, and using

Just a quick comment: If You use Icom ATU such as AH-4, the tuner has a buildt-in attenuator that attenuates the RF signal something like 15 dB while tuning. Hence showing approx 50 Ohm impedance even

Yeah I made a few mistakes on mine. ?So thankful Jeff was able to bail me out.

Certainly! For anyone who wants to print their own: https://cults3d.com/en/3d-model/tool/microphone-case-for-qrpguys-electret-ptt-microphone If anyone wants a printed version with the threaded

You're absolutely right Mark; Hans designed marvelous little transceivers. Mine are working great. On a cautionary note, you might open the Operations Manual and fast scroll (hold PageDown button),

Hey everyone, I recently bought a ready-assembled QMX after my DIY attempt didn’t quite work out (let’s call it a “successful failure” ?). Funny enough, I had no issues building the QMX+,

Martin, I've seen these on other bands as well and I'm fairly certain that this is an RF artifact that comes from the USB connection signaling. See if you can lower the amplitude of those spurs by

The printed case for the qrp guys microphone looks awesome! Are you considering sharing the design? I too have an aversion to taking a beautiful circuit board and stuffing into a pvc tube! 73 Jim

2 Audacity files how? 6 m sounds in Digi and CW -- Martin DK3UW

Michael, Just put a common mode choke 10 feet from your rig in the antenna coax line. I have had RFI cause all kinds of strange interference with my experimenting with all my QRP rigs. I have found

On the WSJT-X I have birdies or whatever they are, which I don't have in CW mode I do have this continuous tone over the whole band as reported before. What can that be? -- Martin DK3UW

Stan, The current thinking is to run the ADC as high as possible without it actually being overloaded. (The bar goes red.) I have the feeling that this is theoretical, I've not seen any research

I have yet to try the K6ARK microphone that I assembled using this mic as well.? Good to know that if it isn't performing quite well enough that it might just be a swap to get better performance.?
