FCC Denies Petition to Utilize 2m Sub-Band for Digital D STAR DOES NOT NEED ITS OWN PLAN if all communication are done correctly and thing thought out . There is plenty of room if people would work together but too many are stuck on OLD The Big "M" does many modes if trunking fail. In my system if the astro P25 trunking fails or I lose the master site, the site controller will still allow for the system to trunk, (single site trunk only) Now if I lose the master site and then the psc9600 site controller and the second controller( two at each site) then the station will no longer trunk. They are now in the failsoft mode each station is now astro digital conv stations The best part here is that When I program up the radio I have all the fail soft and , and control channels etc etc are programmed into the radios So if the system fails. And it ends up in failsoft then one trunk channel is now for the police , one for fire, etc etc etc. And if that fails there are 4 conv analog and digital mode mixed modes repeaters just like my ham repeaters to use in P25 mode Of course it is all how you plan the system before you deploy it . Brent Also correct me if I am wrong there is no way to turn off the dstar system as in remote control? Maybe on the newer systems there might be. I have also not heard a good sounding D system yet. Just my opnion _____

However, one sets up a freq for one or the other in memory. In VFO mode can switch between modes from the front panel. I would think Mot would have simplex modes even in their trunking. EDACS does and here for the sheriff dept set up for emergency ops or when system fails. However, it has been found few officers know how to switch, hi. Since they very seldom do it they quickly forget. 73, ron, n9ee/r Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.

No. If a P25 repeater goes down, you can have a 'mode' (as Moto calls it) that is simplex on the output, and you will be still be heard by any radios in range-IF you're on a conventional system. A trunked system is different, but the radios do still have conventional simplex available, and should be programmed. D* I expect has the same thing. I don't think there is a direct radio-to-radio mode in Mototrbo...I could be wrong tho...
