#QMX first powered test -- is this right? #qmx


 

I finished construction of high-band QMX rev2 (2024), 9V version.? Checked and rechecked all my soldering under magnification and probed for shorts with an ohmmeter.? Time to apply power and do the smoke test.

I set my bench supply to 6.8V with a very low current limit.? I'm passing the power through a ViFly ShortSaver 2 (per recommendation on this forum), but since the current limit on the power supply is set well below 1A, I don't expect the ShortSaver to actually function as a circuit breaker right now.? When I turned the bench supply and the ShortSaver on, the meters on the supply read 6.8V and 40mA.? I stopped there, and did not press the rotary encoder to power up the radio.? Before I do, I want to know if things are OK so far (after all I've read on this forum, I really want to be careful not to blow the QMX up.)? Should there be a quiescent power-off current draw?

Thanks,
Eric
