Hey Chuck,
Not sure about your rig variant, however the older ones
FT-101B,D etc the guys would remove the CW filter, and
with a few diodes on the mode Switch you could put an
AM filter in it's place.
I "Added" an AM filter to a 101B with a simple perf board
thing and double side taped it in there. This retained SSB
and CW and added AM. Still gotta play with the diodes on
the mode switch but since you have to do that anyway
it's not that big of a deal. The instructions are on the web
and come with the Fox Tango filter my cust. had obtained.
Original filters plug in but have nuts on the case to hold
them in place. It worked real nice. I think they only hold
2 filters max.

Hi to all:
I have a Yaesu FT-101FX. The manual states there is an optional cw filter that can be added.
I did not see any additional information on adding an AM filter. At present AM sounds bad. It is being restricted.
(1) How many "drop in" filters can this radio hold at one time, Am, SSB and CW?
(2) I know I can add the CW filter but can I also add an AM filter? I am going to go over the schematic but it is packed away.
I see International Radio sells a 6000 Hz AM filter, SSB filters and CW filters.
Just a note. The previous owner replaced the original SSB filter with a more narrow SSB filter. I have to open up the radio to find out which SSB filter is installed.
(3) Are these filters really drop in or are they soldered in?
Thank you,
Chuck
