You can also use the AFV/dBV function in the radio to directly measure 
the filter insertion loss.

I won't give you a step by step procedure.  That is left as an exercise 
for you.

I will suggest that AGC ought to be OFF, the signal you tune in ought to 
be steady with a good SNR, and that the K3 has an internal oscillator 
around 49.380 MHz.

Enjoy!
