[Xastir] 300 baud off-air data into Xastir

[Dave H]

Chris
I didn't think packet radio was allowed on 160m for UK licence holders?
(sorry OT but possibly important)

Perhaps you should argue a frequency in the 5Mhz band would be a good use?
Though I guess it would take a change, but perhaps the RSGB might get behind
it?
