I will be on 903 & 1296 for the Sat AM sprint. Liason on 144.260.

George, WA2VNV, FN30kv

P.S.  Bill, VE3CRU/R what grids will you be roving?

Microwave Sprint ???

The interest shown thus far in the Microwave Sprint starting Saturday is
appalling.  Not one post on the reflector, and only VE3SMA replied in email.

With thunderstorms and lightning in the forecast, I have cut back the bands
to only 1296 for less aluminum on the roof.  Monitoring 144.260.

Good luck to all who do participate, hope to work you.

Bill   VE3CRU/R
