ONE BOARD FILTER for FT-817ND
ADDENDUM
12 January 2006
If you are installing the W4RT One Board Filter (OBF) into your FT-817ND, you need to be
aware that Yaesu has made an alteration in some lots of the FT-817ND. The original FT-817 is
not affected by this Addendum.
Before installation of the OBF
, you need to determine if your FT-817ND has the alteration
from the original FT-817. (Read the NOTICE on the next page!) Look at the underside of the
Main PCB in the area beneath the MuRata filter. The photo below shows this area. At the end
of each indicator strip, the component indicated is an SMT resistor and is very, very small. A
close-up photograph is shown next.
