This 1550 was working correctly until I upgraded the firmware to the latest firmware from Motorola. On a channel that uses PL the receiver decodes correctly. There is NO PL transmit. I have checked the code plug and there is the correct PL in both the Rx & Tx.
I saved the code plug before I upgraded it. Code plug was dumped into the radio with no issues.
I have searched the Internet without finding an answer as to what maybe causing it.

Re: CDM 1550LS+ UHF No PL/DPL on transmit
After several more hours I finally found my issue.
Under the option board tab the “Flat Audio” drop down box was selected. Unselected it and reprogrammed the CDM. PL transmit works correctly now.
