I live in Hilliard. I have reprogrammed my HP1 to the MARCS IP digital CPD talkgroups, but I am not hearing anything. Occasionally, I hear a transmission from CPD Channel 4 (main dispatching channel for north/central area like Clintonville), but I live closest to Zone 1, 17 precinct. Not hearing any transmissions from Zone 1 or Zone 3, the closest to my house. I have tried everything. Tried just listening to entire database, tried listening to all the MARCS digital channels, etc.

@gthatch - The zones don't matter, the system is simulcast so your proximity to one zone is the same as all the others from a system standpoint. It sounds like you might be suffering from the simulcast distortion that many of us are fighting. Try changing you antenna, changing your location, or adding attenuation.

In R-burg ...I programmed all the sites in Franklin county p-25 on seperate channels and could not hear any C-bus except on the one for the site named Bixby ( groveport) and it was great then ... for now I just scan all the sites but seldom get anything other than on the Bixby site....I think an electric company power station on McNaughten & E.Broad has always interfered with AM radio signal as I pass by it.That may be why I don't even get a distorted C-bus most of the time .It's usually nothing .That power station is between my yagi direction to the C-bus site on Broad St....Does that seem like the power station is a logical reason for my problem .If it is does is there a solution or should I just give up on it ?

Your on the wrong channels, you need to program in the city of columbus Site on MARCS


This one

There are 3 systems in Columbus. Franklin County Simulcast, Columbus MARCS, and Columbus City. Columbus pd is on Columbus City.

57996 might be SWAT just an FYI operating in the clear.
I submitted one to the database update. I also heard other swat related activity on another tg. I couldn't pinpoint it as either a secondary CPD swat group or Franklin county SO swat. It appeared they were working together.

I receive Columbus on my HP-2 however the Columbus system is very susceptible to Multi-path Simulcast Distortion.
Columbus City or Columbus MARCS? I seem to experience the problem on the latter of the two. Columbus City is close to perfect; but the lazelle rd. Tower is almost in my back yard.
