What would change all of a sudden? Isn't the PPS used for system clock?? I used a Pi to read the stats on the PPS, and it is accurate? The previous setup would run long and not decode, so?I went to

May I add there is also a 0.1amp current draw when pressing the left encoder. I have it connected to the PC and the QMX never registers as a device.

Sorry for the late reply on this, I have been busy and had not had a chance to sit down and dive into this. There is 13.8V at PWR_ON. The encoder when depressed does show to have ground. VDD has 1.5

ajparent1/kb1gmx wrote LFP are a better match to common 12V system being closer to the nominal 13.8V (14.6 full charge, 12V cutoff). They hold a narrower voltage range in use. That may well be true

Bill, I am not an expert like Evan, but allow me to share some experiment results with you. T3 Output Waveform: I tried to reproduce the waveform that you observed on my breadboard test set up. It is

Someone else with similar goals. An ultraportable antenna that can be directly attached to a QMX. https://www.youtube.com/watch?v=xbC59sygb1Q&t=24s

Sounds like the U.S. penny might be going away.?? I was inspired by the touch feature of DL1CR's touch feature on his QMX Carrot.? This is pretty easy to print without supports, but you do need a

It works perfect for me.

Hi All, I activated a SOTA summit yesterday with the QMX to test it's SSB capability. I only operated on 40m, with the expectation that local stations would hear me well and many I've worked before

What's the short story on why the onboard QMX+ microphone doesn't work (yet). Is there an upcoming solution? Just curious, Roy de K2RMA

It was said, by one with whom I agree: "Does not seem that showing the rx level on the radio primary screen should depend on whether there is an AGC function. Irregardless though, wonder why AGC does

Allison, Some of them wall warts are pretty good at radiating RF. That being said, creating a clean signal at 30mhz is a significantly different job than designing a 500khz SMPS.? As you well know. A

I had a similar problem but the screens said "WSPR Power" rather than "WSPR Call". Over and over again I re-entered my call sign, getting no change. Then I realized that "WSPR Power" needed to be

?Roy, This is very similar to the one I built from an old modified Radio Shack 110 v heated solder sucker years ago. It works. Here's the pictures. Dave K8WPE

Jerry, What is the difference between a modern wall wart and a class D TX?? No rectifiers, filter is LPF suitable for the band and antenna matching. Oh and stable? frequency source. The hard core

Now the QMX Carrot has successfully completed its second SOTA/POTA activation. And my KX2, remaining in the backpack, is getting jealous. But I almost missed a Summit to Summit due to SWR protection,

No I rarely do am.? ?I did build a retro-75 (SWL circa 2010) that was class E. While trying to may the uSDR work I found the TX made a fair AM tx (modulate the DC to the finals). The large size
