r0f,

I'm still not sure, but I believe the problem is not with the flashcode, but how MotherMoto does 9600 digital trunking.

We have been trying here on the board for some time to be able to monitor 9600 trunking, and have been unable to do so. The radio does indeed affiliate. No matter what. Even tried turning down the xmit level to virtually zero. No joy.

It may very well have been a conscious decision on their part. Remember, all along the contention has been that you have no right on the system without permission, even monitoring.

So it could be that even if all you want is 3600, the fact that the firmware and flashcode have 9600 in it is all it takes to force it to affiliate.

Dunno, but it is a vexation.

Has anyone tried the "hidden channel" trick with a P25 9600 system and a P25 9600 radio? My guess is that the radio will affiliate on the hidden channel...

I've read through a version of the P25 trunking spec a while back, and I remember that it pretty much stated that any radio that is unable to affiliate (because the transmitter was disabled or out of range) will then try to look for another control channel. So with that, I'm guessing that if the transmitter was physically disabled, the radio will just keep scanning for a CC, and keep attempting to affiliate forever. Can anyone confirm this?

The 'hidden channel' trick should work. 9600 baud radios do not affiliate on channels being scanned, just like 3600 baud. Therefore you should be able to sit on a conventional channel, and scan the trunked ones without affiliating. Of course, I have neither a 9600 baud radio or system to try it out on, but in theory it will work. Unless Motorola made the 9600 baud radios a little different, and made them so that they need to be affiliated to a system to even allow scan to function, but I don't think so.
