[SCCC] Effectiveness of MFJ-1026 Noise Filter??

[Steve]

Anybody actually have experience with the MFJ-1026 "Noise-Cancelling 
Filter", specifically whether it's really effective at cancelling 
plasma TV noise (at least, that's what I think my intermittent noise 
is; I'm not about to go next door and ask the nayboors to turn their 
TV off and on in this HOANazified area just to confirm 8-O )?? Is 
there a better-such filter? Needs to go between my FT-991A at 100W 
output and an antenna tuner.

Thanks,
