[Yaesu] Inrad filter instead of Murata filter in second RX Yaesu FT-1000(D)/FT-1000MP

[Hans Remeeus]

Dear Yaesu/Inrad-friends,

In the second RX of the Yaesu FT-1000(D) and the FT-1000MP (Mark-V/Field) 
you will find a Murata 455 kHz ceramic filter. This will be the Murata 
CFJ455K '15', '13' or '5' filter. Perhaps another type, but most of them 
have a bandwidth of about 2400 Hz with slopes like a pancake.

It may be a good suggestion to de-solder this Murata filter and use the 
Inrad 1800, 2100 or 2800 Hz crystal filter instead. You will need two thin 
coaxial cables for it.

I did this in the FT-1000(D) with very good results.

Two picture with an instruction you will find at:

Good luck!
