Hello guys, I am fairly new to the group.. I have been reading and watching about this unit in the pixs and I would have to say it's a ST5 as I still have one and am resurrecting it from my old RTTY  days of about 30 years ago.. I used it back then with a model 19 and made many HF contacts.. Later I used it with a 28 that's geared for 100 wpm and I used the old UART gear shifter technique.. I am putting this all together right now and plan or hope to make a few contacts on HF again..  Skip

I wouldn't consider it that way.  As I understand it the ST-5 was to be
a simple TU for use where signals are good, as at VHF.  While the ST-6
was much more complex and intended for more difficult receiving
conditions.______________________________________________________________
