I'm hearing echoes of Pete Loveall AE5PL's talk at he TAPR convention. He makes the point that DV means digital voice, and the text is just going along for the ride, so don't sweat it. (I'm not sure that D-RATS' Dan Smith KK7DS totally subscribes to that theory.)
Two other points: The wider the bandwidth, the poorer the signal-to-noise. You really don't want to burden DV with more bandwidth just to accommodate more text speed. The 440 UHF band has LOTS of room, at least in Region Two. Acres of space is set aside for ATV, which, arguably, isn't pulling its weight on 440 and should be heading for wider pastures up the spectrum. SERA has some 100 kHz wide data channels set aside from the GRAPES packet days that are mostly fallow (but might be filling up with narrower stuff in some areas). It would be nice if DD (the 128 kbps data mode) could be included in the dual-band radios and repeaters. Some new spectrum management would be needed. 73, Gary KN4AQ ARVN: Amateur Radio//Video News Gary Pearce KN4AQ 508 Spencer Crest Ct.
