Well, that's one of the most interesting things I've *ever* seen!

It does confirm that the January 1945 SHIPS 242A entry for the
TAV is for unit with a transmitter *and* a receiver.  

It's also interesting that the 2000 to 4525 kHz frequency range
is identical to that covered by the early models of the TBX-series
from 1939 and later.

That 300 to 600 kHz receiver coverage is also curious.  Don,
can you tell by the tube lineup what type of receiver is used
in the TAV-4 (TRF, regen)?

This makes me think (a little) of the Army SCR-178/179 set, but
primitive as those sets were, the TAV is older technology.

Notice that the RT unit is "CAY-43002".  (I wonder what system
got the nt-43001 designation.)

The set serial number is 9.  Don's set is likely unique today.
