Ptt id

[dixie729]

I've got a Motorola CDM 1550 LS+ VHF. I have the MDC signaling set up. How can I set it up to where when I key up it sends my unit ID number to a radio and i can see other unit ID numbers when they key up?
Im not seeing an option on the CPS to do so.

Not sure about your radio, but for the Astro Spectra, it's under "Radio Configuration" and then under "Display & Menu" and then under the "PTT" tab. Make sure "ID Display" is checked.

I couldn't find it there.

On the CDM software under each conventional personality (where you enter the freq and tones) is a signalling tab. Go to the channel(s) you want the ID to transmit on and change the TX signalling to MDC-1 (or whatever MDC system you set up). You will also need to select pre- or post- ptt to select whether the ID is transmitted before you talk or after. We set ours for post. Setting the receive to MDC will allow the radio display to show the id's of other units.

This may help:

Step 1: Define an "MDC System":

From the "Feature" drop-down, go to "Signaling" "MDC System".

If more than 1 system, select the system you want to use with the personality at issue; otherwise, stick with System #1.

Under "Primary ID", type in the ID you want to send. Note: valid MDC IDs are 4-digit hexadecimal numbers, with the following limitations:

"0000" is not permitted.

"F" is not permitted in any digit.

"E" is not permitted in the first digit.

Under "PTT-ID Type", select Pre-Only or Post-Only, as you choose.

Select check or uncheck for "Sidetone" and "PL". (As a practical matter, check both. The sidetone prevents you from talking over your ID, while the PL insures that the ID will pass through the repeater.)

2) Step 2: Point your Personality to the MDC System.

Go to the personality you want to send the PTT-ID. Under "Signaling" "Tx System", select the MDC system you wish this personality to use. Note: you have to use the drop down menu, and only validly defined MDC systems will appear. Ignore systems of any other type.

Thanks I got it figured out. I had to set the RX signaling to MDC-1
