I have read about the failure of Toko ceramic filter in various Yaesu radios.
I have a Yaesu VX-7 and a VX-2200 commercial radio where the ceramic filters failed.
I have recently acquired an FT-817 which dates from 2003/4. The ceramic filters seem to be OK.
I wonder if anybody has an FT-817 where the ceramic filters have failed and whether any failure is linked to a certain manufacturing date?
Thanks
