97.221 limits 80m automatic operation with more than 500 hz bandwidth to 3.620-3.635; for verification, see
http://www.w5yi.org/page.php?id=136 As far as I know, 97.221 was not changed in the recent FCC action. Anyone have hard evidence to the contrary? If so, there will be no automatic or semi-automatic US stations running wideband digital protocols on 80m after December 15 -- reducing the contention for frequencies below 3600. I don't know how much automatic operation there is at 500 hz bandwidth, but 3595 to 3600 seems like a good spot for it. 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, Chris Jewell <ae6vw- [EMAIL PROTECTED]> wrote: > > expeditionradio writes: > [snipped] > > Let's be blunt together, but let's focus on the topic instead of > > personality.
