Lloyd, With power off, check the resistance from TX to ground. Is it low/shorted? Check for continuity from the MCU TX pin to the '08 TX inputs. Is the solder joint at the MCU pin good? JZ

Cliff, super, thanks, restarting the qdx, rebooting the pc. I started up everything again. in Minicom I see the *TCXO frequency ? ? ? ?25000000* *Sideband ? ? ? ? ? ? ? ? ?

It looks like you hit enter once too often or clicked on the top item in the list "Configuration". What you should see when you click the top line in the "expected" view. I seriously doubt there is

I attempted to ENABLE the TX PTT+5 volt setting and encountered the same problem as Adrian, YO3GFH. The ENABLE setting reverts back to DISABLE after leaving the terminal. Other settings such as

thank you, I am not getting the screen that QRP-LAB shows in the PC trouble shooting. I connected via minicom 9600,n,8,1 and expected to get the screen shown under? ? ?QDX IS ALIVE AND TALKING ?

A few things I noticed after playing with this firmware today: 1. The CW-R and Sideband parameters still have no effect when altered via the System Config menu. 2. When entering the "Tune SWR"

Please say what do you mean by "confused state". What are you referring to as the "normal" initial screen? It isn't clear to me what you are experiencing that is a problem. To do a hardware reset

Hello, I have just completed assembly of the 20-to-10 meter QMX. Controls and inputs are good (firmware 1_00_014). Receive works very well-great sensitivity. However, no RF output on any band.

I have a good 9600 baud connection, two way, from a pi4 to the QDX. ?The poor brand new QDX is in ?confused

Phil, What did you set as the receive audio card in the Wsjtx Audio config? Maybe a screen shot of that page would be helpful. 73, Cliff, AE5ZA

My QMX works fine for CW, but I am unable to connect it to my MacAir M2 for digital modes. I am using TS-440S as transceiver type and?/dev/tty.usbmodem1101 as my serial port and CAT for PTT method. I

Thank you Scott, I think I’ll give that a try as well. Cheers Dave

Fantastic. The spirit of ham radio ! -- - 73 de Andy -

Nice setup. This gives me ideas for the station I want to carry on hiking trips in the mountains with the YL. 73! Kevin N8MXL

Hi David. I had similar issue. Had continuity between the A points if I touched the tip of the wire, but only continuity between one set of A pads if I touched the pads. What that told me is that one,

QMX performed very well during today's SOTA activation and QSO'd with 31 stations including seven W stations from 14MHz to 28MHz. I found some problems with QMX during the activation and I would like

Brilliant! I love it. Can you tell me about your USB-C trigger board? Did you make or buy? Thx Matt

I've just done a handful of qsos on my QMX, one of something 700+ miles and need to say I love it! There are a handful of things (software) that might be tweaked: - agc (yeah, I know, I know - will be

Thanks for all the reports and feedback, thank you very very much... all great stuff. I am working hard on the firmware today, fixing a number of bugs. I have the WSPR beacon function working
