GE channel guard / private line question

motgeradios · Post by **motgeradios** » Mon Jun 09, 2003 10:54 pm

I am using a GE PCS and am trying to program it to talk to a motorola radio that uses a private line tone of 4Z, does anyone know what I put into the GE software to make it compatible? When I put in 4Z I get an error. Is there a conversion chart or something? Thanks for your help.

4Z = 136.5 Hz

Sorry, don't have a chart - just made a quick search for it...

A conversion chart can be found at http://www.midians.com/pdf/tone_signaling.pdf

If you have a choice, avoid 136.5. That is the same as the turn-off code for systems using DPL and you will have a noise burst everytime anyone unkeys using DPL on that frequency.

The turn-off code for DPL is actually a series of 1s at 134 Hz, which should not false on any half-way decent tone decoder (and has ever presented a problem on any system I've used).
