Subject: [RFI] BCB interference on 160
Hi all,
I recently built a sheilded RX loop for 160 per N6RKs Contest Jouranal artical. 
It is diode tuned and covers about 1.5-4 mhz. I am 
hearing two AM radio stations on 1830 khz.
They are 640 and 1190 combined. 640 is a 50KW station about 12 miles east and 
1190 runs about 1.5 kw at night.
The anetnna is all sealed up and on the roof. I would like to cure the problem 
without changing to back to back tuning diodes.
I'm thinking a series trap tuned to 1190 or 640 or both. Maybe a high pass 
filter.
Any suggestions? I can built it, I don't want to spent $200 for the W3s 
highpass hi hi
Thanks,
Rick, N6PE

If I agreed with you we'd both be wrong.
