Wasn't P25 radio authentication supposed to encrypt the packet header? Or am I off base?
As for the clear/secure issue, disable the switch, slave everything to secure, and OTAR those users who lost the keys... Right?

They lose their key somehow and 1) can't call their team and 2) can't ask for an OTAR.bezking wrote:Wasn't P25 radio authentication supposed to encrypt the packet header? Or am I off base?

*sigh*. A high power transmitter on the control channel output or on the conventional repeater output in close enough proximity to an operation will also render the subscribers useless.
This is a non-issue in my mind, except for the encryption being switched off.
