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

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

Thanks Curt and Enzo for the information.? I am using battery power to run the QMX + and the DC voltage is 11.8 volts. Sounds like I am good to go then. 73,? Doug

All seems to be well with my Ultimate 3S now. I misunderstood about the dBm power setting in the menu, thinking I could control the power for there (although I couldn't see how). Now if I understand

Its a speaker, not a fan ;-) I also have a small audio amp in there.

I use exclusively a power-bank and simple PD trigger cable for my QMX and QMX+ power.? One is 12V, one is 9V.? They work flawlessly.? And the small Anker 10000mAh power banks I use are smaller than
