Re: QMX+ no power output, low SMPS bias current


 

I picked up an oscilloscope multimeter, (50MHz bandwidth) and checked the signal coming out of the QMX+ and got some interesting results.? When I tried to transmit through the Diagnostics in the Terminal, I got nothing, but when I used the Tune SWR function, I got clear sine waves on every band except 6m (to be expected as it's outside the bandwidth of the scope).? On 160m and 80m, for example, it was a roughly 1V signal.? On 60m it was closer to 5V.
?
It's been decades since I did any EE in college, and signals processing/RF was never my strong suit.? What else should I be looking at?
