I was also thinking of getting some better filters for it. What do
you recommend for program listening?


For AM mode I like a filtronetics marked 6.8khz that reads 6.1

For nice fidelity Sideband, I like a filtronetics marked 3.24khz that
reads 2.9

Both are crystal filters originally intended for the Racal 6790/gm.

They have very steep skirts, and the radio sounds beautiful with
them.


Is this them?

They don't appear to have a web site. Do you have part numbers on the
6.8 KHz filter? Another question is what did it take to install it in
the 7030+?


I found a web site by them http://www.filtro.net

Here is a page with 455KHz centered crystal filters among others
http://www.filtro.net/products/filters/filters.asp

FN-860W 6 KHz/3 dB - 19 KHz/60 dB
FN-169W 3 KHz/3 dB - 6.2 KHz/60 dB

They don't have any 455 KHz ceramics.
