Roy: I did in fact post that it was a 12V QMX. I did not build it, however; I bought it from someone else who had. I have to admit I had forgotten to pay attention to what the power source (an Anker

Thanks for the reference, Alan! Eric

It's a 1-time $1.99. And what virtual USB port are you talking about? The app gives 3 choices #1 Hold the? phone up to the radio (yuck!)#2 Build a custom cable to hook up audio to your headset jack#3

I have a homebrew magnetic loop with a 10 foot coax outer loop that tunes 30m - 15m. I always (or at least usually) tune it with a nanoVNA before connecting my radio.? That way I can make sure the

Hi Luis - I've used iFTX with my QMX using a USB-C to USB-C cable. Haven't made a video on it yet, but it works like a champ. Just requires setting a few threshold values correctly for Vox. Worth the

There's no need to change to CW-R mode at all regardless of what band you are on. It's just a user preference. -- 73 de Roy - KI0ER Littleton, Colorado USA

Just some quick thoughts on your observations. RE: low watts out on 30/20. They share the LPF pair. Inspect solder joints, turns on the toroids, capacitors etc. Fiddle with spreading and squeezing

Lee - yes, that's exactly what I did. Anode to U101 on the top of the daughterboard, and Cathode to the 3.3 Volt VDD pin on the bottom side with a short wire.?73; Steve, N3SB?

Has anyone had experience with QMX + iFTX with the virtual USB port? The costs that apply US$ 1.99 are annual or monthly, I can't find this thread on my iPhone 72 Luis

Hello Chelin, in digital modes it works in USB, I only do CW and my question is if I should change the mode to CW-R like I do on the K2, Ft817, Xiegu X6100 etc? Luis LU4HK -

So it is just a way to allow the radio to function only without transmitting?? I see why that would be helpful for CW, but not so much for digital modes. Bob KG5GTE

Hello everyone !! I'm Luis LU4HK, and I have a question with my QMX 40-20. When I use the 80-60 and 40 meter bands, I must change the configuration to CW-R or the mode is recognized by default. 72

Those are usually mechanical meter zeroing adjustment screws, for zero setting, not calibration. 73, Don N2VGU

There is no one-size-fits-all answer, indeed, I have used 2 or 3 different irons/tips on a single board, depending upon the PCB involved.? Smaller pins/components with tighter spacing need a smaller,

We have a Ultimate3S running at the club and has been running with no problems for over a year. For some reason it will start it's transmission sequence and at the end of the first transmission it

Check to see if the metal edge of the left encoder is touching the top of the barrel socket on the main board. Hans suggested covering that with tape to prevent that possibility. -- 73, Dan - W2DLC

Some helpful numbers to post would be the voltage you built your QMX for, and what is the overall input current draw in receive mode of your QMX? For a 12v QMX you should see around 90 mA or so of

Eric, I certainly can't help with coding:-) The Softrock/QRP Labs RXs are limited by the hardware which, I think, will not go much above 60-70MHz. So to use them at VHF you would need a mixer or

I have the New PCB with the power supplies on the main board. I will inspect everything again. Steve where didyou make connection for the D103 ? I am thinking , mine on top of the PCB? IC101 output
