good morning everyone, yesterday morning I wanted to do a test with the QMX second high band version with firmware 1_00_015, the first transmission went very well, the time was set perfectly by the qlg1 and it gives me 7 w output, not a single band antenna perfectly tuned to 20 meters with swr 1 or -, the problem is that on the second transmission and all subsequent ones it did not transmit any power, the swr protection was deactivated, have any of you had the same problem or know what it could be, it would be the case update the firmware to 1_00_016?? Thank you and good day.

Hi Philip
I just did a single WSPR transmission on 40m with the GPS plugged in. See attached... Not burning any DX but then again my power supply is at 7.5V (12V QMX) and it's 40m and still daytime; furthermore my antenna wire (long side of the OCFD) fell down and lies on the metal roof. It really doesn't work well, it stops the internet working in my entire house, even at such low power! Anyway no SWR tripping...

Stand alone only.
Then that's very strange. I'd wonder in that case if there is some common mode feedline issue (a.k.a. grounding?issue,? a.k.a. in shack), and perhaps adding your GPS connection does something that pushes the SWR over the limit - though SWR and common mode currents aren't the same the causes and symptoms have some relation... to test it, I'd suggest checking with a dummy load.?
If you do still see it on the dummy load then please could you show me exactly what WSPR settings you used and describe it so I can try to reproduce it? Because here everything is running just fine on WSPR with the GPS connected. As a general rule, if there's a software bug, I have?to be able to reproduce it before I can fix it.?
