Without very expensive test equipment, there is no way to calculate
the correct length needed to match a transmitter to a duplexer. The
correct length will seldom be some an exact wavelength or simple
fraction of it. The terminal impedance of a transmitter can change with

The normal deviation for 2 meter repeaters is +/- 5
kHz maximum, with or without PL. PL deviation would
typically be 750-800 Hz but that's usually not
adjustable separately, so whatever you get when the
overall deviation is 5 kHz is what you'll be stuck
with.

I believe these repeaters are based on the
MaxTrac/Radius/M1225 product line; as such they
probably output 25 or 45 watts. You would need to use
the radio service software to turn the output power
down, however it will be unstable and quite
inefficient at such a low level. The power won't

One thing that hasn't been mentioned so far, and one thing that is quite
important, is that regardless of the suggestion of 5 or 4.75 Khz, it must
be noted that these are PEAK values, not average.
If the average deviation is set for 5 KHz, then the peaks will be

Shouldn't the touch tone pad tone be set at the maximum deviation or
nearly so? Those are steady and not subject to peaks. Also I take

I agree. DTMF is two sinusoids. You don't want the limiting action to distort
the signal. BTW this is also why you should use 3KHz as a baseline on linked
systems to keep the audio as linear as possible through chain-linked RF
repeaters.

Good point. I guess the best way to check the deviation is to put

to re-read the book on that.

The R100 will NOT do both PL and DPL. It comes one or the other. To change

It depends upon which one of the four models of the R1225 you have. Here
they are:
M03GRC90C2AA, 146-174 MHz, adjustable 1 to 10 watts
