instructions will give you a working exciter as
long as there is no component issue in the exciter.

Since we are retuning to 147.330 transmit and 147.930 receive, we are at the
end of the band that should help. Thanks to all for the reassurance.

Now that you have helped me close out the old Spectrum issues, can anyone
point me to the list of caps and their new values to convert the exciter
board of a Master II station? On the NHRC site I see mention of the need to
change out a dozen or so caps but no other references.

Well, guys, I promised to follow up with the results of my attempt to repair
the old Spectrum 1000 with the later model receiver. Thanks to Larry and
Joe, I have determined that my receiver is not an SCR200A but probably a
later model of the SCR-200. I obtained at least three versions of the
of it and acquired a MICOR with a unified chassis. Best
money I've ever spent. Worth every dollar.
Good luck on getting the system up and running.
73,
Don, KD9PT

the receiver working! Just one
question, was the test duplexer tuned to the proper frequencies? Was it
desense or just loss of sensitivity when using the duplexer? In other
words, were you able to hear distant signals with the transmitter turned
off?

Morris,
My schematic for the SCR-200 dated 5-17-82 shows Q101 as an MRF901
transistor. My schematic dated 7-22-86 shows it as a 6033.

They are plastic but if the other components are in metal boxes it may work
out ok.

Hi Guys,
I’m new to the list and have been just lurking and reading the mail but now
I can use some help finding a replacement transistor. It’s for a Spectrum
Communications Corp SCR200A receiver. The transistor in question is the
input RF transistor. The schematic is difficult to read for
