Having the same issue. Got it working for several days straight. Then turned it on a few days later and it can't find the microphone again!

Some more on the QMX mid band high noise. First let me describe the issue. Turn on the QMX. Very loud static/noise. After about 10 seconds, the noise becomes intermittent, and then goes away

Many thanks Chris, i'll try to acquire a regulated power supply during the Holidays and get back to you in January. Sly VA2YZX

They are not intentionally crossed; it is best practice to avoid crossing the wires on the windings. However as you note, it will not have a noticeable effect on the functionality.? When orienting

I would use a pre-made buck-boost converter, like this one I got from amazon: https://www.amazon.com/WWZMDiB-Automatic-Converter-1-25-35V-Adjustable/dp/B0CCHPPKW4 or just search for buck boost

I bought some great cables from? Fannoday on Amazon.com recently. They are very good quality, high speed shielded cables at a reasonable price. -- 73, Dan - W2DLC

No problem Brent, glad to help, we’ve all been there, you’ve only got a few years on me. 1961 vintage myself. Cheers Nick G0OQK

Hello all, When I go portable, I use a 12V Makita drill battery which voltage varies between 12 and 10.5V. It is really convenient, the circuitry protects against shorts, it is in a robust case and

Looks really interesting. Have you got more photos to show? 73 de Yannig - F4IUJ

Hi I am looking at the WTS transformer instructions, and notice that the wires on the non-tapped side of the primary seem to be crossed. Is this intentional or a trick of the light. I don’t think

Folks, I cannot tell you how fantastic it is to see so much help offered here with this group. I am fully up and running now and everything seems to be just fine. Anecdotally, I have a UNIX working

Until Hans fixes it through programming a lower PA voltage for 160m and 80m I would recommend against operating or not operating above 10v supply since the PA transistors are actually operating above

I agree with that - particularly since the wall chargers are also often 'noisy' in their generation of the DC voltages. But when using a PD Battery power bank, the confusion factor is not there, and

Good result John, glad the damage was limited to the MCU. ?You are correct that the power setting is only an indication inserted into the WSPR message. The only way to vary the power in the U3S is by

I've been using NiMH batteries for various rigs for some time now, and was planning to migrate to 18650 batteries. But my Iniu LiPo powerbank with 9V trigger cable was so inexpensive and convenient

Ron et el ....... I am up and running on my Macbook air thanks to Pierre.? This is going to be such a great help on my POTA excursions and other portable operating with the ability to control the

Hi Stan, MANY MANY THANKS.? Even though pin 7 visually had a good looking solder joint, when I tested continuity it was giving me some resistance instead of full continuity.? A touch up with the

Yes Ron that is what I select - TS480 I looked a little further and you can control the QMX from SkookumLogger. It's a bit tricky as there are sooo many shortcuts and having a MacBook Pro keyboard
