[TenTec] which power supply setup?

[Clayton Brantley]

Well said Jim.  I just do not want to contribute to the trash on the air.
I use an old GE repeater supply that has a battery charger and relay toprovide power when the local power drops out.  I did add my ownpass transistor ckt and crowbar that keeps the output near 13.8 volts.
Without the battery. it was near 16 volts and that's just a bit too high.
I'm looking at some of the newer caps to see how they would work here.

It's not being old-fashioned, it's being SMART. Switchers are well known 
to produce lots of RF trash. You may not realize it because there's so 
much other trash in your neighborhood from OTHER switchers. Switchers 
CAN be made RF-quiet, but it requires very smart design and costs a bit 
more, so it rarely happens.
