o.k. folks. how about some honest feedback/advice. I am now semi-retired and thinking about getting back into the hobby.I am in no. summit county, about 3 miles from the twinsburg/chamberlin rd. tower. I want to monitor the cuy/summit counties MARCS and the GREATER CLEVELAND systems. Also Portage cty. It is either the bc436hp or the sds 100. MAYBE the trx1. I will also consider upgrade to dmr/nxdn keys if your input indicated.(only for the Uniden units, of course)Any advice is appreciated. Thanks in advanced.
