[1000mp] W8JI INRAD roofing filter measurements

[Pete Smith]

Put it in, Dave - takes 10 minutes and the difference in contest conditions 
is remarkable.  I suspect that this will turn out to be some sort of 
measurement anomaly - why would inserting a 6 KHz filter in the first IF 
cause such marked deterioration in measurements with 2 KHz spacing?
