[MRCA] RT-70 progress

[Radio Station KW1I]

I think we ought to work this in to the tactical event Saturday morning.
Send out a two or three man team with a HF rig on the other side of the gap.
Al, I think you had a place identified.  Put up a vertical and a NVIS and
compare reports.  The PRC-47 would be a good rig to use.  I have others of
lower power that I could dispatch on a mission with Gene.

Gene, if we operate 60 meters during MRCA, do you prefer any particular 60
meter frequency?
