Wayne,
I have been told you could use the FM filter in any mode, RX and/or TX.
I hope that is so.

The problem with using ssb for AM receive is lots of AM guys are using
old rigs that not only drift, but modulate the VFO somewhat, or they jump
around like crazy (heathkits a lot), so a real AM detector works much
better then SSB would!
You don't even notice the problems, which is a good and a bad thing,
many guys drift off 3kc or more and no one knows it.
I use a freq counter to monitor my TX, have a professional mod monitor,
and a scope on the RX IF so I can see everything TX and RX, but many guys
just have a dx100 with a d104, or a homebrew, with no monitoring equipment.

Part of the fun working some guy with a Millen rig from the 1930's along
with a guy running a flex radio, a homebrew class e rig, etc....

That gives a lot to talk about!
