Kevin,
I have no clue. It has probably been 12-15 years since
this thing was converted. I assume the channel
elements were done professionally since the tag on top
of the channel element has 146T85000 on it (146.850
MHz).
Why do you ask?

I'm not exactly sure what you're asking. Microstrips are basically just
sections of transmission line. A transmission line doesn't have a
frequency - it has a length and a characteristic impedance.

Are the transistors rate at 220 MHz? RF power transistors are made for a

Steve,
Yes you can. This base uses 1 RF PA to drive 2 RF PA's. There is a splitter
and combiner before the 2 PA's and after. You can remove the splitter and
combiner but you will need to turn down the 1st PA. It is not hard to do but
you would be best to run the as is, just lower the drive a

First off lets go over some numbers...
38 watts = 45.8dB
16 watts = 42dB
So 38 into the duplexer and 16 out is roughly 3.8dB loss not

I don't have a Motorola 2600 but I do have an IFR1500 and it doesn't
always measure RF power anywhere close to what my Bird watt meter

I tried another channel element and the error was worse. Both the xtal
and element are on their way back to ICM. It will be interesting to see
if ICM admits an error or blames it on the element.
