BC785D - fix for intermod?

[WD4CQ]

I have owned (2) Bearcat BC785D Radio Scanners for over 6 months now that I really enjoy, However I get lots of intermod. I am using the scanner as a base with an outside discone antenna.

Question? Does anyone have any experience or success using these filters
below on the BC785D scanner and if so, which one? If I had a handfull of filters in my possesion, FM band, Business/Paging band and different brands, I could try them out and simply know which ones worked and which band to filter out. I do have a powerful FM station in the area on the low end of the FM band, also a powerful NOOA station on 162.4 Mhz and the common 152 (somewhere) Mhz paging freqs in my area. I love the BC785D but the intermod is driving me nutz! Any experience from anyone with a BC785D?

I noticed the the 785 is slightly more prone to intermod than the 780.

I have heard good things about the PAR filters, but I have not used one. My problems come from 926MHz pagers. I have used the Stridsberg FLT800 with pretty good success.

I found that lowering my antenna from the peak of my roof to a lower area over the garage helped even more than a filter.

A directional antenna can also help if the problem transmitter is not in the same direction as the target transmitter.

Good luck, and don't forget you can always MOVE.
