[RFI] RFI FROM nearby AM station

Happy Holidays, Everyone!

I am looking for a practical, reasonable-cost way to keep RF from a nearby 
AM broadcast station out of the receiver of my IC746 when I have a 160M 
half-sloper connected to it. The station is three miles away, transmitting 
1 KW on 1340 KHz. 

I would like to notch the station out, if possible, so I 
can listen to other BCB and LF stations on the half-sloper when I am not 
using it for transmitting. If that's not possible, I would guess a 
high-pass filter is my next alternative, but I will entertain all approaches. 

The IC746 doesn't have a separate RX port, so I need a filter with 50-Ohm 
ports that is capable of handling 100 Watts in transceive service. 

I welcome your input. 

73, 
Tom, KT9OM
