The earlier editions of the ground version of the radio- the BC-191-
did have a couple of additional units.  I have a TU-3 that 
covers up to 800 KC (don't remember the bottom limit).
The transmitter was originally designed in 1928 and 
speced down to 125 KC, so I assume there was a plan
for a TU-1 that covered 125 to 200 KC. 
I've never seen one so perhaps they weren't produced.
