Most antenna specs in the band are for 800 kHz max. That's why our area has 500 kHz splits - for duplexed repeaters. We also have 1.0 MHz splits. As any 1.7 MHz bandplan would destroy the 500 kHz split band, I don't foresee that happening here anytime soon. There is also the fact that everyone around is is running either 500 kHz or 1 MHz splits.
There is also the fact that there is a local TV Channel 2 station which forces usable systems to the lower part of the band. With a 1.7 MHz split, that means all your TXs will be within 1.3 MHz of the broadcast interference. Granted, that will change next February for us (and become a problem for others), but that's only one solid technical reason for not going with a 1.7 MHz split plan. Joe M.
