I just got my QMX, a few days ago. It was already flashed with 1_00_019, but after i flashed it to 1_00_020, the text makes no sense. I had to use the jumper trick, to get into firmware mode.? I

Niche case maybe but some of us like to listen to the digital sigs for sensory reasons. I find the warble of FT8 very soothing and when I operated the mode I always listened to it as it was very

Hi, Did you ground the tx before measuring current drawn? Also does the voltage on the drain pins vary as the potentiomer is turned? Check these first. Andy -- The universe is made up of Protons,

Hello everyone I ordered and assembled this PA. I followed every step as carefully as I can while assembling. When the pots closed fully (to counter-clockwise) current consumption is 140mA stable

Hello, I would advise you to visit local grocery story into food storage section to look for food containers. They are waterproof, good and solid plastic and the most important - you could get an idea

Hi Jim Don't worry about it. A bit low, borderline, but acceptable. Device component variations... there will hopefully in future be a calibration function which evens out all these variations by

My QMX+ "seems" to be working OK, although 20-17-15 meter power is a bit lower than I'd hoped - just under three watts. Anyway, tonight I fired up PuTTY and was looking at the diagnostics screen and

Thanks Hans. All the fixes worked for me. Love the radio. Moving on to development board. You actually got me in digital modes finally, because.I can hear the audio. That humanized the feel and allows

Hello Hans, Thank you very much for the detailed explanation. I found the document very useful. I'll keep exploring until my QMX gets home :-) 73, Gabriel LW2DVL

GPS is more vital when untethered from a PC connected to the internet. The U3S does wspr standalone because of the GPS. If you operate your rig somewhere remote without any connection to the web nor

I have proven that it is possible to fry IC402 with too much RF on the input side. :( Did you have an antenna connected to your QMX while you were transmitting with another radio ? 73, Steve, N2IC

How are you powering it? I had an issue similar to this when the buck-boost converter that I was using to limit input voltage was silently clipping the input current (due to a bad setting on my

Just a quick update regarding my issue with the LCD: I ended up sending the rig to *Jeff Moore, W1NC* , for further inspection. He did an AMAZING job of troubleshooting and fixing the LCD data

"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
