I'm using both an SDS100 and a Unication G5. I'm based in Berlin Camden County about 1 mile from the county line and about 6 miles from the nearest transmitter in Kings Grant Evesham Twp. The SDS scanner does a great job from anywhere within Burlington County so far based on hearing TGID 3601 (Burlington County Hwy Dept patch from UHF) and still good coverage at my home. The only issue there is difficulty with voice frequency 769.56875 which is close to 769.69375 which is the control channel for the Berlin site of the NJICS about 1 mile from me and very strong. But that's the only issue with the SDS100. I get perfect copy on my G5 all the way down to the Turnersville area (which is the beginning of Gloucester County) and improved reception within Burlington County - particularly around Atsion Lake which had been weak previously. I really hope the county gets the ball rolling on switching over soon. It's really needed especially coming into the late spring and summer months where DTV interference becomes a real problem during the nights.
I have not tried to receive Trenton yet, but Mercer County P25 starts to come in on my SDS100 around the Mt Holly area using a Larsen Tri Band antenna. It's pretty solid around Bordentown and Mansfield down towards the Columbus Market.
I can monitor the Ocean County P25 system using the Unication G5 from my location in Berlin. I get just enough signal if I use an adapter and scanner antenna. Mind you, that's about 30 miles away from the nearest transmitter in Plumstead Twp. Reception is better anywhere north and east of Medford and can even be heard from the Batsto area on the way to Tuckerton.
Hope this helps. Let us know if you need more advice about scanners and antennas. EMTd99, where are you located?
