Sorry i am totally new to all, so please bare with me and i will try and explain the best i can. I was at the local shop today trying to clone some portables and change some features. What i wanted done was on one of my talk groups, 14 channels, i dont want the last 2 channels to transmit for accidental reasons and also when radio is on scan, it will key up on channel that last transmission received although it is physically on different channel. Now from what the guy was telling me that it is a trunking system and that in main menu there is no box to check for receive only, unlike the conventional menu where it is on main screen in other channels programmed in radio. Now he also tried to take out the transmit frequencies and was un able to do that. As far as i understood, it is a P25 system, or Astro. He said when he clicks on transmit boxes does not alow him too edit. Is there something that we were over looking in the programming software? He also said something about a Key, we switched radio companies, so they are not the original company that set the radios up. is there a way to get this key code or is it even needed to just change those 2 channels to receive only and to clone the other radios with all same, just with different identifiers for each. Thanks for your help.
