In another thread, another user had a similar issue. He deleted the system on the scanner and then re-added it and holds are now working.Noticed something interesting last night. First a scenario set up. Both my SDS200s are programmed exactly the same, both have DMR/MotoTRBO activated, both are firmware updated equally and both have the exact same antennas connected to them. I get very good strong reception of our state's P25 phase2 statewide system. I noticed that when the same TG came on at the same time on both scanners, with signal strength being identical, and I pressed "hold" something different happens. One scanner just shows the frequency, the other, keeps changing frequencies even though it is on hold. That has never happened before. I did this a few times to make sure it was not a one time thing. Very strange. This happened after I did the firmware upgrade. Not sure if it is related or not but it is an obvious change. Just putting it out there in case anyone else experience it.

Another thought also, what happens if you switch the SD cards, does the problem move to the other scanner?
