In Reply to: Try running the FM6 vertical. It seems to me that local conditions are telling you something posted by Timbo in Oz on November 10, 2006 at 22:33:17:
Can't do that - the roof supports are at various angles and locations, such that even horizontal, I have to mount the FM6 only 2 feet off the attic floor, barely miss the supports in one area. If vertical (elements vertical, boom horizontal) rotation will be severely restricted. It would be possible to rotate from NW to N only, though. Or S to SE, take your pick. Great idea, though.
BTW, forgot to say, the roof and attic walls are non-metallic, vinyl siding. A lot of wires snaking all over the attic floor, though. There is no electrically clear area to mount the antenna because of that. Really sloppy wiring, they just lay on the rafters, running directly from one place to the other, no design at all.

Aswe say down under, give it a go. Search - on 'antennas' AND 'FCC' - here

I'd rather not irritate my neighbors and fight with my HMO. There are other ways to get what I want. The signal atrength and quality is OK, the noise I'm getting on my favorite FM station (WGMS, Wash DC.) seems to be from "HD radio self noise". WGMS is one of those who broadcasts HD digital FM out on the sidebands, and the tuner in my HK 3480 receiver doesn't have the narrow-band IF filters to fully "scrape off" the HD outliers. Even so, it does a reasonably good job, have to turn up the volume pretty high to hear the background "shhhh", especially with the FM-6 antenna. Although the FM-6 doesn't deliver higher signal strength than the vertical folded dipole, its signal results in better quieting. Brian Beezley suggests I install a post-detection filter in the tuner section to get rid of this residual HD radio self noise.
Dale.
This suggests to me that the SS meter on the HK is one of those 'light UP on a wet string' meters I have come to know well.Once they're at about 80-90% on the dial they take a LOT more signal before they - barely - move.
I hate IBOC, Sirius and daat reduced audio in all its forms except MPEG2' audio layer at 512 kbps and adjusted for performance on transients / attacks that begin all notes. On OUR national public FM-Classical(Jazz too!) service that's what the - necessary - satellites transcieve, and it IS okay.
Not as good as it was - I reckon ;-)!- but acceptable, and their live stuff is amazing - still!
CD is acceptable, but analogue tapes or broadcasts of acoustic concerts - on a good 'unprocessed' FM station - can still piss all over it.
As can music IN the studio with the announcer. Strikingly good. Let alone interviews!

http://www.audioasylum.com/forums/tuner/messages/5529.htmlWhile the post-detector filter goes in - a suggestion I would second, also get the tuner checked/aligned, and tweaked. NB Power supply behaviour and decoupling - can be a BIGger audible issue - around certain chips even in front-ends, than can putting sexy parts in the audio output stages. Good but sensible $$$$$ parts are vailable anyway, right up to excellent like stock but selected styroseeal caps.
