Scott, I suspect it is a version of the RTTY keying modification that
Drake published a paper on many years ago. It attached to the VFO
and the keying was accomplished by keying a negative voltage from the
RTTY unit, probably through that red wire. The modification had a
few capacitors and coils and used diode keying to shift the VFO
frequency.

Subject: [Drakelist] Weird Modification on T-4XC PTO
I'm considering purchasing a local C line station. The transmitter is
a high serial number in very good condition. Under the hood there is
an odd and poorly executed modification.
Here is a photo showing the transmitter with the mod box. Maybe you
can take a look at it and comment.

The 82 yr old owner vaguely remembers the mod. He said the mod has a
Berghardts sticker on it. He told me the box has two air wound coils
and 3 capacitors in it. He thinks it's got something to do with the
PTO but doesn't remember. He mused that it might be to reduce drift.
The mod is very poorly executed as the box is attached to the PTO with
black electrical tape, and some red house wiring. The OT is the
original owner and last used it in 1992. The T-4XC serial number is in
the high 26K range.
Anyone recognize such an oddball modification?
