Hello. You can reprogram the atu-100 so that it will tune from 1w input.? There are lots of instructions on the Web for how to do it. In the protection menu you can then adjust the tune % to output

Hello Colin, thanks for your reply. I don't want to bypass the SWR measurement, it's the safety shutdown of the QMX transmitter at bad SWR. Before Hans implemented the SWR protection, I could usually

You could defeat the SWR measurement in the QMX. -- Colin - K6JTH http://tangokeys.com

To all HF specialists: I use the inexpensive and good ATU100 automatic antenna tuner. Works well and is very inexpensive, I have already built several. The transceiver whistles with about 5 watts or a

Here are various FLIR images of a working QMX radio - Total output was about 2.5 watts (on 11 volts) into an antenna on 20M and a dummy load on 30,40,60 and 80M. The "shack" was pretty chilly this

Your dental hygienist will usually give old picks away for free. Back when I taught SCUBA, we'd get free dental picks to remove the O-ring from SCUBA tank valves. And when one of us got a handful,

And now it works, rf filter sweeps keep changing.

Now my swr sweeps show flat lines at 10. No power out when tuning in diagnostics. Swr protection trips. Dummy load attached. Yikes. I really broke something.

I did a recheck of L401. Everything seems good. QMX was A+ 100% beofrw i attempted the diode mod. The issues on 20m and 30m are new, after diode mod attempt. 73 K9PZ

Yes, Stefan, that is a short! ... JZ
