[Yaesu] ceramic filter problem in FT897/857

[Dr. Gerald N. Johnson]

I've not detected any ceramic filter problems though I did run a SSB 
mechanical filter for some time in my main 857. I've since traded it off 
finding not a great improvement over the ceramic filter. Going to the 
mechanical filter and making it the default would be a relatively simple 
work around compared to changing the soldered in ceramic filter.

I know of one 857 with a display failure and that was 4 or 5 years ago 
on a radio only 2 or 3 years old. One work around for that would be to 
go to software control through the CAT port where you could customize 
the computer front panel to do away with the menus replacing them with 
127 buttons. That work around does limit mobility however.

You might ask a radio dealer with a repair shop, like Dan at Radio City 
Inc (www.radioinc.com). Give him a day or two to recover from hamfesting 
and then he'll be preparing to go to another hamfest and will be a Dayton.
