Today I cleaned up the HP-20 power supply, and started re-forming the caps.
I have a fine cap checker, and I can bring up the voltage slowly. Two caps
good to 450 VDC so far.
However, it may be a waste of time.
The MT-1 Cheyenne band switch was stuck on 40m. So while the caps were
cooking I opened up the MT-1. What I found may kill the whole project.
There are two band ceramic switch wafers in the circuit, one is inside a
shielded cover and 90º to the other wafers. Looks like it has something to
do with the VFO/OSC circuit. In any case, it is cracked. Unless I can find
a replacement for it, this project is finished.
Anyone know of an MT-1 being parted out? Or even one for sale outright?
Thanks.
