I recently finished building my QMX+ and all the testing and diagnostics seem to be working well. I also hooked up an EFHW antenna and was able to receive CW on multiple bands.

?

However, I went into terminal and ran some diagnostics and on every band I get a power reading of 0.0W and no SWR return even with a resonant 30M EFHW attached. Should I be concerned? I would've expected a power level to be read here.

?

Thanks!

Jon,

could you show these values, connecting a dummy load to the QMX:

- Output, measured external

- Supply current when sending

?

Do you find a "P" (practice mode) or a "S" (SWR protection) in the first row of the display?

Hi Ludwig,

?

Thank you for the very quick response!

?

Below are the configurations set for the radio.

I don't have a dummy load on hand and assumed, probably poorly, that using a resonant antenna would suffice.

Jon, whats with a "S"? Maybe your antenna has more than SWR 3 and the SWR protection kicked in?

(Resonant doesn't mean a low SWR in all cases.)

?

Which current when sending?
