[RFI] Telco Data Update

[Jim Brown]

I've added common mode data for the K-Com RF-2 Broadcast band filter.

This data confirms KI6KY's claim that his filters have signficantly 
more common mode rejection than their K-Com equivalents. His 
broadcast band filter is 6-12 dB better, depending on what frequency. 
His HF filter is equivalent above 8 MHz and 6-8dB better below 5 MHz.
