As the \nother fellow drifts down, you can adjust your RX down to compensate. Your \nTX stays the same (from the ground).\nSince the VFOs are not linked, there is no difference between tuning the RX \nVFO down and tuning RIT down...the only advantage to be had is if for some \nreason you need to know your \"starting point\" RX freq.\nThe only way to truly keep from walking is computer control. No dice with \nthe FT-726R.\n\nNow someone is likely to correct me on that last statement...but even \nradios with tracking VFOs, track at a Hz-per-Hz rate, don't they? My \nIC-821 does...so if you manually tune, even with the VFOs in track, one \nlink is a little off because they need to track at 3:1 (at least for VU and \nUV modes).\n\n\nAt 18:54 2007-10-01, Bob Stewart wrote:\n>--- Scott Townley <[email protected]> wrote:\n>\n> > I don't understand why you'd need RIT...just tune the RX VFO?
