I am using the hidden talk group method and do take my chances getting inhibited. My chances are much lower than most as I don't use the first couple of radio IDs and choose an ID of a radio I know would not cause conflict if it were to transmit (which isn't a problem since I read the CC data myself and confirmed it isn't transmitting). I can still be inhibited but the chances of the admin just killing all active radio IDs is much less than killing non-used IDs. We just need to make sure some idiot doesn't affiliate with the system (or any system) and the admins start hunting rouge radios down.Hidden talk group method is different than the scanning talk group method.
Yours, if using the accepted naming of the method requires programming in the trunked system into the radio. The other does not. Thats when you need to guard who has access to the radio and how it's programmed and with what keypad limitations.
That method can still result in an inhibited radio if the system admin decided to send an all-kill command. We did that years ago and the local message boards blew up about radios no longer working (we had a bootleg problem and took a different approach to it)
There are two ways to "scan" an astro25 OBT system without affiliating.Astro25 OBT radios do not track P25 P1 systems reliably and will not unmute.
You can use the talk group scan method and a couple of others but it's the same deal - but it's actually not tracking control channel information.
Tx inhibit on the radio will also not work.
The lastest uniden firmware sounds very nice. The audio quality between an astro25 and a scanner is the speaker used. The APX line uses a better rated speaker and new algoryims that enhance the sound - but much also has to do with the transmitted radio settings. Garbage in garbage out.
The new Harris stuff is rather good and sounds great.
I'd rather use a scanner to scan 1000 tg's than 15 on a Motorola. Too much liability should you lose the radio or someone wants to play. Unfortunately many people who use commerical equipment do not set it up properly and cause problems.
