James,

You can program a pin on the accessory connector to do exactly what you
want, and even make it active high or active low to be compatible with your
controller.  It is better to let the radio do the encoding and decoding of
CTCSS tones, since you have the reverse-burst STE built-in- a feature that
is normally not available in aftermarket controllers.

We are using a pair of Motorola CDM-1250 UHF mobiles, 403-470 split, for our
UHF repeater along with an Arcom RC-210 controller.
 
We want to strip the PL tone when CW and / or Voice ID's are sent.  The
arcom controller has the capability of sending logic out to the radio or an
external tone board to turn the encode on or off.
 
Does anyone have any knowledge of how one might be able to inject the CTCSS
logic into the 16-pin accessory port, or otherwise connect to the CDM radio
and control whether the CDM will encode our PL tone or not?  
 
Another option is the CommSpec SS-64, which I have on hand.  However, we
cannot simply parallel the tone output into the pre-emphasized audio input
of the radio.  I know that the radio could probably be programmed for no
pre-emphasis, but I don't want to bypass limiting.
 
Ideas or suggestions?  Maybe someone knows a good location to inject the
tone directly into the radio's modulator?
 
Thank you,

I got to looking in the schematics, and was going to try injecting the tone
at U0221, pin 40, which is supposed to be the MOD IN, as it's labeled, but
it's really the audio output (after all filtering, etc) that goes to the RF
stage.

Instead of doing that, I found in the software that if you program pin 8 to
"TX PL / DPL Inhibit (input)" you can actually control the CDM's PL tone
encocoder.  I checked on another repeater we use, the Motorola R1225, and it
has the same option, I think it was on pin 6, though.

If you find out how to do that, let me know!
I gave up and switched to Tait TM8110 it allows ctcss injection.

Look at the help files accompanying the CPS program, especially the ACCESSORY 
Configuration tab, ACCESSORY Connector for pin definitions and the ACCESSORY 
Pins Tab.  Also look at the manuals for the i20 repeater controller and the 
Z340 Comunity repeater controller.

One of the options on several of the pins is TX PL DISABLE (INPUT).  Definable 
as High or Low for active level.
