"...Since there is NO two PL's the same, the problem went away..."
---------------------------- The problem [intermod] did not go away - you just masked it so you don't hear it. It is still causing degradation of the receiver's effective sensitivity. --------------------------------------------------------------- --- In Repeater-Builder@yahoogroups.com, "Jim Cicirello" <ka2...@...> wrote: I can tell you that the same tones on different frequencies inside the same site can cause a problem. My 2-meter repeater was on 151.4, the same tone as the local high band fire and channel on the VHF community repeater. When a combination of the units with 151.4 came up, I had inter-mod on my 2-meter machine. Also at times there was noise on the fire that we could tell disappeared when the 2-meter dropped along with the community repeater. Luckily I own the tower so I was able to move my 2-meter repeater to 123.0 and it happened that my private channel on the community repeater was also 151.4 which I also changed. Now I try to make sure that every PL inside my site is different. Since there is NO two PL's the same, the problem went away. Our Motorola Tech told me this is common at tower sites using the same PL on different frequencies. 73 JIM
