[K3PZN-List] Field Day from W3CAR

[mellema at qis.net]

To All,

I participated in FD with my new club  W3CAR (Chesapeake Radio  
Service)...had a good time but missed the gang back home. It sounds  
like you had a another great event...very good.

I worked K3PZN Sunday morning on 40  CW...don't know who the operator  
was but suspect it was Curt or Steve (Ny3A)... BTW I worked NY3A  
Saturday evening also on 40 CW.  We used a G5RV slopped...worked great.

Best 73's
