Re: [Repeater-Builder] Motorola CDM-1250 PL tone control
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.

Re: [Repeater-Builder] Motorola CDM-1250 PL tone control
If you find out how to do that, let me know! I gave up and switched to Tait TM8110 it allows ctcss injection.

Thanks, Milt. I found that yesterday and it appears to be working.

Re: [Repeater-Builder] Motorola CDM-1250 PL tone control
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.

RE: [Repeater-Builder] Motorola CDM-1250 PL tone control
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. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of James Adkins Sent: Monday, October 13, 2008 12:10 PM To: repeater-builder Subject: [Repeater-Builder] Motorola CDM-1250 PL tone control 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.
