Hello all. I have an FT857. It is quite noisy, on rx, even with the antenna
disconnected. Is this an indication of the ceramic filter problem? (In RF not
SQLCH mode) Or, just what is the give away for this problem. My FT817 has a
better rx noise figure so, hence the question.

The FT-857D is being serviced at this time so I don't have it in my
possession. However, the FT-897D I recently purchased has a date code of July
2007 and it has the same ceramic filter issue. The rig was essentially new in
the box with the sticker attached to the display so it was never used. It
seems the defective filters degrade over time whether the rig is used or
not.

I contacted Yaesu about the ceramic filter issue and the tech said he
wasn't aware of the problem -- I find that hard to believe.

Hi Tony:
Could you give us the DATE CODE and LOT
NUMBER of your FT-857D? I'm trying to figure out if Yaesu fixed this problem
at some point during the rig's long production run.
Thanks/73,
Howard, W6ZZ
