Hi Chris My results here on a QMX+ 160m: 2650 80m: 2650 60m: 2650 40m: 2650 30m: 2650 20m: 2650 17m: 1150, subsequent one-off tries 1200 15m: 1500 12m: 1350 11m: 1950 10m: 700, subsequent one-off

Hello, I installed the new FW and have some trouble. Under Win I see Audio - QMX Transceiver - ok Audio - USB Audiodevice - not ok Com - STMicroelectronics Virtual COM Port (COM <x>) - ok Com -

In FT8CN settings turn off no track CQ and no track call and the software won't be so "automated"

Jeff do you have a link to that PCM1804 replacement part? I may need one (or two)?

Jim: Sorry, for the delay - Percocet, don’t ya know ! It was C16 I had set up as a sorta QSK switch like the cover photo. My idea was to use a TRS or TRRS plug where (usually) the T and R (or R1)

Randy, Many of us are getting very different calibration curves, some of the phase ones look crazy. Your phase error plots that don't go up to about 2600 (x-axis, 12V build) are 'incomplete'.? You

More info on USB naming, I just checked again the way QMX does it. I attached a screenshot of my /dev/serial/by-id directory. There are three devices, named by their "Interface ID", which are 00, 02

Maybe not, Diarmuid... we don't even know that Mac doesn't do it yet... 73 Hans G0UPL http://qrp-labs.com https://www.buymeacoffee.com/g0upl

The solution is simple, upgrade to Linux, Jan. Diarmuid EI4LF [email protected]> wrote:

Hi Jan It's done on QDX already and I intend to do it on QMX too. It only works on Linux. On Windows, the OS ignores the name you give it and always gets called COM4, COM5 etc. What happens on Mac

Is it at all possible to set up virtual COM ports so that they will have a consistent name when (re)connecting? I've found that under MacOSX, the name changes every time you plug it in. This makes it

Calibration of QMX+ completed.? Results below: (three QMXs to be tested) Some phases stopped early 160m? 1100 80m? ?1300 60m? 2500 40m 2600 30m 2600 20m 2500 17m 700 15m 700 12m 1500 10m 2300 6m

What would be the symptoms if this component was failed? I set the QMX aside for now to take a break. Troubleshooting this thing all day made me tired. Just to know for when I pick it back up, in case

Hi Chris I would call it Beta until the SSB phase distortion calibration is more Please can you try it in this new beta version and let me know what you find? 73 Hans

I would call it Beta until the SSB phase distortion calibration is more robust. Chris

Glad you found the culprit, it’s possible that sharp edges in the core damaged the insulation on the wire. The component most as risk from that short is Q507. 73 Nick G0OQK

Yes!! That fixed it. It powers on now :))) Hopefully the high current didn't fry anything else. I wonder what happened with the transformer.. I wound one exactly the same for QDX the other day and it

Yesterday I decided to venture into the latest beta release of QMX SSB. I'm nearly 100% CW op, so this was mostly done out of curiosity. I'm a big fan of Hans and QRPLab, and have been impressed with

Hi all I updated the SSB beta testing webpage of the brave, here: https://qrp-labs.com/qmxp/ssbbeta.html and released firmware version 1_01_004 to it. I did not solve problems with SSB phase

Removed one leg from L502 and still had short to ground on both primary and secondary of the T501. I removed it and currently rewinding.
