Very happy to report that after eliminating the wall wart and connecting CRX1 to the ham shack power supply that everything works! I was able to hear a few CW QSOs happening yesterday morning and could tune around without any problems. Not entirely sure what frequencies I’m listening to though (somewhere between 7.030 and 7.034 MHz according to the specs).
Now the next step will be to figure out where to put the Astron power supply so that it doesn’t take up a huge amount of space on the workbench and so I can use it to power future experiments/builds. Might also be nice to have something like a RigRunner that’s fused and will let me connect multiple devices.
