In Reply to: I am beginning to think so too! and am wondering about putting it in your loft with an earthed MESH ground plane under posted by Timbo in Oz on December 30, 2006 at 21:32:53:
If they are wide-band source/s, and close, we are in some trouble.OTOH a/several powerful nearby 'discrete bandwidth' source/s - that are actually OutOfBand - can / might be causing RF overload somewhere in the RF stage / front end - which appears as audio hash.
This seems a likely cause to me as this - OOB RF-overload rejection - is one thing only a few SS FM tuners are good at. While few valve FM RF stages are poor at it.
Filtering or cut-to-frequency yagis connected OOP may help cancel its effects.
If slight OOB RF overload IS the case, maybe an FM techie nearby knows about it and can address it.
? IYTMM!
