What have list members found to be the best low pass filters to prevent TVI? I
currently have a Drake TV-1000 in line but that allows RF up to 52mhz, and
actually above that because I have used it successfully on 52.525mhz for 6m FM.
Today I borrowed a Kenwood LF-30A from a friend. I can't find too many specs
on it other than it has 90db of attenuation above 90mhz. It didn't make any
difference compared to my Drake. I was thinking that it might do better since
it should have a lower cutoff frequency.
I see that Drake also made a TV3300 filter that is rated at 80db above 41mhz.
And the ICE filters get good reviews on eham.net. So, any opinions as to what
low pass filters work best?
