"why one would need to have audio on in Digi modes?" I disagree, though I agree that /some/ would not! My ear can't decode the signals, but I can hear how everything is going. Agree, that it's

I find it useful if I am trying to debug another radio setup (listening to the signal coming from the other radio).? Definitely prefer that audio remain available for listening in digi modes.

I have 2 factory built QMX's, a Hi & a Low Band. They are used for DATA comms only. Recently the Low Band radio has been acting strangely. When it begins to TX it gives a pulse - the TX bar graph goes

Hi Ludwig, I think the time sync has to be done correct and not just at the about right maner. Bseides one can observe the spectrum to get the information about the start. For the use of the wide band

Thanks for putting that on Hans! Learned a few things from your slide show as well as some insider info I didn't know. If you are a QRP Labs fan (as most here are) this is a must watch if you aske

I managed to build my QMX successfully, and in two days of playing with it fried the receive function.? W1NC Jeff Moore diagnosed and returned the radio to full function:

If I don't have a proof of time sync listen to the audio and watch the computer clock gives me a first impression of sync. And in the moment Digi is the only way to listen to SSB I think. 73,

... what I want to say is that the audio volume of one Continuous Wave signal in BW of 300 Hz is about equal to the SSB signal in the 3kHz BW. Considering the characteristics of a SSB signal. But you

Yes, that is the way to do it. These display's backlight is really bright. I have even used greater resistor there. -- 73 Bojan S53DZ

Hi Hans, thanks for this FW release. A thought: I wonder why one would need to have audio on in Digi modes? Just mute it. And enable the audio in the third (not yet there) mode to have the choice of

Good stuff, Randy! Those toroids really are self shielding! -- 73, Dan? NM3A

GA Bill, I have used various WSPR units for 7 or more years without having a GPS until my U4B came. It’s such a joy to turn it on and walk away, the time, grid and so far load automatically and

Maybe you can replace R306 (33 ohm) on the front panel board with a small 100 ohm pot to adjust the brightness. I was thinking of doing it for my QMX (not plus) not necessarily for the brightness but

Thanks Hans, a self calibration feature would be great. My QMX+ is just under 1W on 6m and I would like a bit more, that is quite a lot under spec.. Thanks for all your efforts.. 73 Dave G4FAW

Does anyone have an easy safe method of dimming the backlight on the QMX+ Perhaps changing/adding a resistor. The bright backlight is fine in a well let room or outdoors but in my dimly lit bat/ham

Thanks Geoff I fixed it 73 Hans G0UPL http://qrp-labs.com https://buymeacoffee.com/g0upl [email protected]> wrote:

Just tried this. After update, CW sidetone clicks like crazy. I had to set "S9 sounds like" to 9. It was at zero. Tony AD0VC ________________________________ Sent: Thursday, July 11, 2024 12:17

Thanks Hans, Always love seeing new firmware releases. Just a note that the href link to the operating manual on the QMX page is still to the 1_00_018 PDF even though the link description says it
