Batboard

One of my coworkers has a secure VHF Saber I . We use MDC1200 on the dispatch and Fireground freqs. His radio stopped passing MDC and would only send it when the emergency button was activated. I took it home and checked the settings in the RSS. Everthing looked normal, I had the original codeplug from when I programmed it. Still no MDC.I built a new codeplug from scratch. Nope. I tried an identical spare saber and the codeplug from the original worked in that one. After about an hour of no luck I tried a different secure module.. Low and behold that was it. I replaced it with a spare dummy module and aligned it and checked it over. We shal see if it holds up
