Hi Nate. Transmitting and receiving.? I'd like to put a switch on the PTT going to the amplifier so that if I want the amplifier in the circuit, all I do is flip the PTT switch so that the amplifier

My experience is different, Chuck.? A simple roll of wire (certainly not exotic) I bought on Amazon from a quality manufacturer happens to have a high-temperature enamel.? So yes, I can burn it off,

Unless you are using some exotic insulated wire, a few seconds of exposure to the flame of a butane lighter will easily burn off the enamel. After you have done that, there will be a little oxide

Joel, when replacing the transistors 'next time' if there is one: just cut off the body of the bad transistors, leaving most of their lead-length in place and soldered to the board.? Then lay the new

If you didn't scrape the enamel off the newly-twisted 'A' center tap on the right side, those two wires won't contact each other, and you won't have continuity between the two left 'A' points - even

Jim, are you talking transmitting through it, or just receiving? Nate N8BTR

The same with me. Smtm you need to press PTT twice to start tx. 16:35, 25 March 2025, "Howard Lamhut via groups.io" <howardlam@...>: QMX… I have the SSB software installed

Purely a firmware thing, I believe. When/if the BASIC comes, I want to customize the UI so that a single click of the left encoder puts the QMX into band select mode and you choose the band by

Thank you Brian I was thinking about that and I will definitely give it a try. Thank you

Hi. You are logically inconsistent.? If I have 3 points A,B,C and A connects to C, and B connects to C, then A and B MUST show continuity to each other. I suggest you check your

You won't have continuity between all the P points UNTIL you twist those 2 P leads together. This threw me as well for a bit.

No point to clean out the holes when replacing the BS170's, about all that does is damage the board with all the heat. Just clip the new leads short and lay them flat across the top of the holes,

I managed to get through the steps to build the RWTST version of the transformer. I'm getting caught up on Step 14: I have continuity between the secondaries. I also have continuity between the

Thank you for kindly answering my question... I truly appreciate it. I suppose I could have known that Hans already addressed this, but I admit that I have been unable to keep up with messages. I

Sometimes if the knobs are installed with not enough clearance for full down travel you can get double clicks.? If this seems like a possibility, try raising the knobs on the shaft a little. Brien

Rather than use the microphone input I have been running Fldigi into the USB and having some nice QSOs on Olivia. Olivia has amplitude modulation of the envelope (unlike wspr or ft8) due to how the

IIRC, Hans already has stated that the calibration must be done at full power, which makes sense as it is a way of measuring, and compensating for, the non-linearity inherent in the final amplifier

Joel, I calibrated mine at 11.1 volts, battery voltage dropped with 3 diodes in series and it all went well. I continue to operate at that voltage and the output is slightly lower than it was at 12

I had the same thing happen... QMX+ is on the bench with the BS170's removed, and one of them indeed tested bad. While waiting on my replacement BS170's I am carefully cleaning out the holes. I really

QMX… I have the SSB software installed version three and made one contact with good audio reports. The only thing that is strange is sometimes the radio does not go into transmit when I press the
