cdm 1550

Alright, so I have a setup of some HT-series portables, which notably includes an HT1250s that I recently programmed to be able to transmit MDC statuses and MDC messages. I have a CDM-1550 LS+ (the 6AN model) as a base station that I operate on only conventional channels. Now, on both the HT1250...

Hi everyone. Currently trying to set up MDC1200 on a couple radios. Came across the signaling menus when trying to edit a conventional personality being greyed out. Find it strange since I could configure a mdc call list and edit some options. But I cannot apply it to a channel. Weird. I'll put...

Hey everyone! So I’m trying to program my CDM1550 and I keep getting the error saying it can’t find the radio in the COM port even when I select the correct port that’s stated in device manager. I’m using a programming cable I bought on eBay as well using a windows 7 virtual machine which I...

Hi, I have a LB CDM1550 radio that has its squelch set too tight. The squelch breaks at ~-111dBm or .63uV. I need to readjust the radio so squelch opens at ~-120dBm or .21uV. Using a comms tester I read the radio using Moto's Tuner app (admittedly I have only used CPS in the past and have no...

Hi, Just wanted to show the repeater project im working on. Im open to any questions or advice. I also encourage others to show what setup they have. I would consider items that would be posted in this forum to at least meet the following requirements: 1. Any home made repeater system with a...
