Hello. Newbie here. Just promoted to a new position and now am responsible for about 400 portable and mobile radios. Before the previous guy left he purchase about 45 APX 6000 radios. Before that we have used mostly XT 2500 portables and maybe about 30 APX 4000 radios. I was familiar with cloning radios and could do that and then add them to the system using Provisioning Manager. Problem I have now is trying to get the 6000 to work. I have programmed one of the new 6000 by setting it up by looking at a 4000 codeplug and setting everything the same in the 6000 codeplug. Added radio in PM and 6000 can receive but when push PTT button only get an alert tone, not able to transmit. What am I missing? Any thoughts would be helpful.
