[Lowfer] WA schedule for tonight

Thu, 30 Jan 2003 23:31:43 -0500

Bill,

I see you on 185.300.45 so you are slightly higher then normal.
Conditions here tonight started out good then took a dump!
So as of 11 Pm signal levels are poor, except for Mitch's MP
which is very strong. Hard to tell if your signal has improved or not due
to the current band conditions.

73
