[Yaesu] FT1000 (D) or FT2000?

The roofing filter kit was from Inrad.
The fan upgrade was from the K6JRF web page.
I highly recommend that you take the radio apart, clean it and the fan assembly. Then install the resistor that speeds up the low speed setting. These two make the most impact. It takes some nerve to gut a FT-1000D. Put each screw back where it came from. There's a lot of them.

I too have an older Ft-1000D circa 1994, still a great radio but it now takes it's place as my backup for a ICOM 7800 a very terrific radio. However I was intrigued by your comment below regarding adding Roof filters and quieting the fan noise (always has been objectionable) Can you describe the process or refer to location I can get it?

You have posed an interesting question. I also have been looking at the
FT-2000, but still have a '1000D on my desk. This one is an older unit,
built in 1991, I've gone through it and added the Inrad roofing filter and
the cooling system mod so that it's quiet.
The issue with the FT-2000 is its front end, so I found a place where I
could download the FT-2000 service manual to compare against the '1000D.
Now while the FT-2000 is a nice radio, it's not really in the same class
as the '1000D. I suspect if Yaesu were still trying to build a FT-1000D ,
the selling price would be around $5K. Yaesu stopped building the '1000D
because they couldn't get some components, not because they couldn't sell
I put the front-end schematics side by side. Decided that Yaesu still
likes using a million tiny relays. Why they decided, on the FT-2000, to
put some of the bandpass filters on the large main board and some on a
daughter board is beyond me. The FT-2000 roofing filters are just single
pole monolithic filters. The original '1000D had two filters cascaded.
I think you get the idea. I've decided to keep my '1000D, at this point
and wait for the 'Digital Cat Wisker" radio to show up. Good luck with
