Wider splits would be nice. Usable duplexers would be more available and less costly. . Sent on the Sprint® Now Network from my BlackBerry®

Actually, it's happening now. There's a very dedicated (and, apparently, very wealthy) group of hams using the Public Safety P25 digital protocol on both VHF HB and UHF ham bands with some discussion of trying it on 900 as well. Even on the ham market, that equipment isn't cheap and well out of my area of interest. As for the wider splits, performance is such that I see no reason to change now. In the '60s, that may have been a good idea. Tom DGN --- In Repeater-Builder@yahoogroups.com, "Rev. Robert P.
