Main Receiver 3rd IF Filters
These filters include small boards with connectors,
so no soldering is necessary for their installation.
© Disconnect all cables from the transceiver, and place
it upside-down on the work surface.
(Remove the ten screws indicated at the right, and
remove the bottom cover. o
Referring to the photographs below, determine the
location(s) of the filter(s) you are installing, Figure |.
Except for the XF-C filter (XF-455K-262-01),
which replaces the standard ceramic filter, a diode must
be cut away at the new filter location, before installing
the filter, as follows:
XF-D (XF-455K-202-01) 2.0-kHz BW filter: cut D2047
XF-E (XF-455K-501-01) 500-Hz BW filter; cut D2046
XF-F (XF-455K-251-01) 250-Hz CW filter: cut D2045
(Cut the diode at the filter location(s), and then posi-
tion the filter so that its connectors are aligned with
the mounting pins on the board, and push the filter
into place.
(J Replace the bottom cover and ten screws removed
above (unless installing other options now).
