I am newer to programing my departments radios. We have access to multiple trunked systems, the first system gave us the system key. No problem there. We are gaining access to a second system and are working on getting the second system programed in some of our new radios. The radios were sent to a local radio shop to put in the VHF and second trunked system. Will I be able to add the first trunked system without the second systems key? I was told the second system will not give us a key. I know the way I wrote this is a little confusing and am sorry about that. any other questions to clarify this let me know.
