Trying to use ARC4 encryption on 878UV (FW 4.0) to talk to a Mot XPR7550, simplex.
When I try to transmit the 878 on a DMR channel with encryption on, the transmit light goes on momentarily, then off and signal icon shows signal momentarily then off. The 7550 receives the 878 ID only momentarily, but no audio at all. If the encryption is disabled, ID and audio are received fine. This appears to be a xmit issue, but I did triple confirm that the hand-typed keys matched.
A bit cornfused - what would cause this?
**EDIT - this happens when either ARC4 or AES is enabled
