[INRAD] FT1000MP second RX Murata filter

[Dean St. Hill]

Hi Tor,

I too have done this mod on a Mk5 FT1kmp field and plan to do it shortly on a Mk5FT1kmp (200watter). 

In the field, I've used an inrad 2.1Khz and wired it in. I find that value very good for what I use this rig for - contesting. I believe others have also tried the 2.8 filter. I was in several minds in terms of what filter to use on the second rig, but have settled on another 2.1 KHz.

My personal observation is that now the sub-receiver sounds like you'd expect a primary receiver to sound. It's very very crisp with excellent selectivity.

Ideally, I would have like a 2.3 or 2.4KHz filter, but while I believe the Inrad Collins mechanicals would work, I figured I'd stick to the Inrad crystal filters.

Hope that helps.

  I am interested if anyone else has made the modification to change the original ceramic Murata CFJ455K in the sub-rx of FT1000MP to another type of filter for example one of the Inrad´s, as did Hans Remeeus in his modification pages. http://www.remeeus.nl/english/hamradio/ft1000subrxfiltering.htm
  Has Inrad done any tests with this question, and do they have ready-made replacement filter to it.
  What would be the best suitable filter from Inrad to replace the original Murata CFJ455K.
