For anyone who''s looking at their Heil HTH-* handy talky headset, like me, here are the three wirings that would need to be

Thanks! I went out and bought a syringe with flux paste, but it's very hard to dispense and apply it. What you have seems a lot better.

One thing I noticed, probably general and not specific to this release, is that during TX the power meter does not really follow voice peaks very well compared to an external peak reading meter or

This is the circuit I use for my Heil microphone, this just has a TS connector, no ring. Chris, G5CTH

It could be one of the protection diodes on one of the buck converter boards. Those are D106 and D109. -- 73, Dan - W2DLC

Selling QMX+ V1 unbuilt kit. $125 ? Will include case and free shipping to lower 48. ?I just have too many QMX’s HI. ?Email is good on QRZ. -- Trevor (N0YMA)

Thanks, Stan.

I just saw the other thread where Hans explained that the internal mic is used as the reference for the noise cancellation. -- 73, Dan - W2DLC

It might make sense to ship the board with only the small parts stuffed, that should be most of them. The few large parts could be obtained locally. Fragile small parts or those mounted vertically

Successfully built my first transceiver ever, the QMX, a few weeks ago. ?As a novice with electronics, it felt amazing to complete. ?I have tested it several times in the backyard, and everything

Any built for the (tr)uSDX will have the correct wiring.

Welcome to the world of SSB. Everything may be fine. Turn compression up to about 10 and you should see a bump up in output power. With SSB, many/most external wattmeters are not fast enough to catch

Do any of the commercially available hand microphones for existing QRP radios work with the new QMX SSB? Or perhaps pre-wired adapters for those mics already in the marketplace? Bill? W3WJ

Joe, this sounds to me like a problem related to the 5V SMPS board. Power off by itself could be a result from a broken D101. Which Rev. is your broken QMX? There was a known issue for one or two

Relays are even thicker. Plus group buy manager will solder female programming socket under the pcb which will make the package about 2mm thicker. So cheap envelope shipping for the ATU board is no

All of my old gaming headset adapters short the tip and ring, putting input mic audio on both.? So I can't use them for qmx.

Sometimes we all need someone else to shine a light into our rabbit-hole and help us back out. Stan KC7XE

I finally bit... Ordered some .3mm (28awg) colored copper craft wire from Etsy.? Shipping included, it was under $10 for 100 meters of wire.? On a per inch basis it is 4x more than a quarter pound

Interesting thought. Karl wrote: First just turn agc off and see if the nature of the issue changes. If you have the first parameter turned low, like S4 or so, it could be cranking your gain up so

Measuring again and seeing what the 10 volt rail does during transmit, I see that it drops to about 9.85 volts on the rail and 9.37 or so at the input to Q508. This gives something like 9x10^-7 amps
