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.
