Greg and List.

In Australia the TT4 was the main TTY used in a portable role.
That is, non shelter mounted equipment. So a vehicle mounted TTY station 
would have something like:
A suitable radio (PRC-47, GRC-106, C11/R210, Radio relay (B70) etc
TTY terminal eg AN/TCC-14 or 29
TTY machine AN/PGC-1. The TT4 was made by Kleinscmidt I suspect in the 
1960s. $250 each is rather expensive I reckon.
Unless you really want the military PGC-1, I would suggest having a look 
for a Siemens T100. Lots of them were used in OZ for Telex

I'd love a dollar for every time I set up and used this type of 
equipment during my time in the Army RASigs!
I quote the RASigs Aid Memoire Sep 1968 for more details on the above:

AN/PGC-1: Teletypewriter Set. Portable station; TT-4 and Generator PU-181.

requires 20 mA or 60 mA signal current; supply 115 V AC; part of AN/PGC-1.

AN/TCC-14: Telegraph Terminal. VF FSK telegraph transmission and 
reception; consists of TH-5, TA-182, F98; speech plus simplex (with 
break in) telegraph operation.

signals to and from VF tones, 1325 Hz mark, 1225 Hz space; 2-wire 
simplex or 4-wire duplex operation; output 20 mA neutral; supply 115 V AC.
