[Mich VHF UHF Society] [NEWSVHF] 222 MHz FT8 - Inquiring 9s Wanna Knw

Yes, please coordinate with all the other digital modes, and coordination 
with existing VHF+ weak signal groups (ex: Central States, NEWS, etc) should 
be a goal as, in the recent past, some groups have coordinated new 
operations in a vacuum (amongst themselves) with problematic results. A good 
example was the debacle of choosing 144.390 as the national APRS frequency 
on top of both the TransAtlantic cw beacons built by weak signal groups on 
both sides of the Atlantic
, and the national AM calling frequency on 144.400. The beacons and AM'ers 
easily peacefully co-existed, but the APRS group's poor choice put an end to 
that. We have plenty of spectrum, we just need to find out where our 
neighbors are already operating.

Spectrum in the area plus or minus 222.200, (say, 222.180-222.250) and 
432.200, 902.200, 1296.200,  etc and up into the GHz range might work for 
digital frequencies.
CW and SSB operation rarely goes above .150-.180 on these bands.

I'd suggest coordination with the WSJT folks. That way anything decided can
get integrated into the WSJT-X software. There is a very active mailing
list.
