Did you just buy the crystals and insert them in the ICOMs or did you send
them in to the crystal MFG to be compensated. If you did them yourself the
compensation is probably now messed up. The best way to fix it is to send

Tim,
I have a two meter repeater that outputs 250 watts (approximately +54
dBm) into the duplexer. After the 93 dB of rejection that the duplexer
provides for shear power reduction toward the receiver port, -39 dBm of
transmitter power leaves the duplexer receiver port - headed toward the

Is there an issue running one of those at 25 watts continuous? It is a

Hi Kevin,
Thanks for the info. I've used the PLL MastrII exciter on a couple of
systems also.
Now, since this duplexer is of the 'notch' variety, I already have about
100db of notch (on the TX side) that is tuned to the RX freq. Shouldn't
this be enough?

With 250mW (+24dBm) into the transmit port... antenna port is
a quality 50 ohm load, I see -72dBM at the receiver port. (pretty
much what I expect.. 1.8dB loss through the xmit side, 100dB
notch through the RX side.
Those numbers are fine.
With it all hooked up receiving an input signal

Hi Jeff,
Thanks for the reality check... loved the real-world example of
the mobile unit.
At this point, I'm leaning towards the bad mojo/karma phase
of the moon!
Got a 'spare' set of low-band cans that need to be stored somewhere
it's warm? :-)
Thanks,

Larry - I didn't.
The 250 watts is produced by a GE MASTR Pro/II 4EF5A1 capable of 330
watts continuous. The MICOR high-band tube amplifier, IMHO, is junk
compared to the GE 4CX250R based VHF power amplifier. The 4EF5A1 is
designed to operate from 144 to 174 MHz. without modification.

The less gain is related to the internal filtering stages,
not the device. I would expect the version with the GasFet
