[MRIC] D-Star and SERA

Tue Jul 15 13:32:24 EDT 2008

Most of the restructure will cover the HF bands and hardly touch the  
VHF/UHF bands, so there may not be much change.

It would be nice to know what PA is doing as far as band plans for  
repeaters as well since they are to the north of us.  Anyone have any  
idea?
