Thanks very much, Butch.

I'll add these notes to my growing "how to" file of instructions on the RS35
output voltage adjustment process.

The 590 is noted for being very sensative to input voltage.  You really need
to measure it at the radio.  It wants around 14 volts.  If you get much
below, power starts dropping off.  It is easy to adjust the voltage on the
astron supply, but if you're not comfortable working on such things, you may
not want to try.  The main regulater board is usually mounted with component
side down, foil side up and is screwed to the large electrolitic capacitors.
If you feel under the board, you''ll find a pot, about the size of a dime or
a little largger.  It is mounted on edge and you can adjust it with a
finger.  Don't go very much undil you know which way you need to go.  Also,
if you go to high, you'll trip the ovp circuit.
