Hi
I have GE mstrII rack mount uhf. AU88b last four of the model. I have

read your web pages you stated that the ge pl ctss board does not 
transmit pl tone . On my system board I have a card that is 
(PL19D4172GIGG rev b with 110.9) . 
That number does not seem right.
I'll bet that you have a 19D417261G6 board.
I hook up the controller per 
repeater builder web page. Works great as long as keep the GE stock 

controller card in  with the repeat disabled. My problem is I would

like to have a pl to be transmited. The recieve side works fine 
drops 
the voltage with the proper tone .  I have the controller connected
to 
RUS 0v-3.88v ,cas has 0v-9.8v just testing info for you.
I would like to find out a way to remove the ge internal controller and

have the pl for recieve and transmit . The external contoller does not

have ctss option. 
Decode, encode, or both?
I have the manual been
reading  don't want to put a 
jumper from decode output to exciter connection without some facts.

The decode out signal is a logic level that feeds to the repeater
controller.
If you do have a 19D417261G6 board look at LBI4743 at 

According to that LBI your G6 card is a decode only version.
To do what you want you will need to find an encode-decode 
version of the board you have (ending in G1, G2 or G5 - the 
G5 will do split tones), an encode-decoder model of a different 
board the 19D432500 is the dip switch board, and is covered 
in LBI-31056. The G1 board is the encode-decode board, the 
G2 is encode-only, G3 is decode-only.
Or you can just add an external encoder.  Several are available,

or you can build your own - years ago, I made my own encoder
from a simple one transistor twin-T oscillator with a one-transistor

buffer amp.  Using polystyrene caps and metal film resistors
gave
me an encoder that was stable from 30 degrees to 120 degrees F.
