[NLRS] 24 GHz snow scatter QSO

[Barry VE4MA]

Congratulations Mike & Jon,

This work is outstanding......blazing the trail for others to follow!  I am 
really looking forward to the 2006 RS season to see what 24 is like.

In looking at the radar traces the snow looked surprisingly dense ( wet?). 
That is not what the light powder looks like here...but will have to keep a 
closer eye on what is down in the Fargo area

Best 73

>> Mike, KM0T (EN13vc) and I worked on 24 GHz snow scatter at around noon
