  If they're both running 1/4 whips, I'd say 25 miles in mostly-open terrain.

  Probably out to 40-50 miles...

  If they are DB-201 antennas, which are 1/2 wave folded-down
ground-plane antennas, 50 to 60 miles.. if the're running yagis,
might be up to 100 miles.. better with SSB than with FM, though..

  As far as I know, you can still run digital on 6m, but hardly anyone
else runs digital on 6m... and yes, control should be at 220 or higher...

  Growing old is mandatory.. growing up is optional. :-)
