It gets worse. Soon we'll be seeing systems (Denver looks to be the first) moving to APCO 25 'Phase II' and all but the newest of the digital trunkers won't be able to deal with that. As for Radio Shack, they are not yet selling a model that copes. Uniden seems to have been the first to jump on this with their BCD436HP/BCD536HP handheld/base pair.
