[Hallicrafters] HT-32 PTT and CW break-in mods?

[Peter Bertini]

Hello to the group

I just traded for an early SX-32 transmitter, and I'm going
cross-eyed trying to following the relay keying circuit through
the maze of operating and function switch contacts.

So, to make my life easier--is there a good source for
modifications to allow for VOX operated CW keying and
changeover,  as well as a means to add manual PTT
that also disables the VOX feature?
