As long as we're discussing power supply issues, i've just had an experience
I never expected. My RM-35 from Astron failed and, oddly, the problem
seemed to be in the switch. You'd think it would be somewhere farther along
in the circuit. I was on cw and started to hear an odd sound every time the
transmitter in the k3 keyed. Like an arcing but different in that it wasn't
a snappy sound. At first, I thought it was the rig but then the transformer
in the supply started to jump occasionally, as it does when you first turn
the supply on. When I started to smell smoke right after that, I hastily
signed and reached up to turn off the supply but the switch wouldn't throw.
it moved a bit but was actually fused in place. Later, when I came back
down to the shack it had cooled down and was very firmly fused in place. I
had another, older Astron on the shelf so I hooked it up and was back on the
air the next night. I haven't taken the cover off of the stricken supply
yet but it oughta be interesting. It's not a complicated device so I expect
to be able to fix it. Anyone else have a similar experience? Lou WA3MIX
