I think the DT-500 was more like the ST-5. The DT-600 was closer
to the ST-6. I had both the ST-5 and the DT-500. I perf-boarded
a DT-600/ST-6 hybrid too.
Details of all of that are ancient history, so consider the
possible memory degradation. All are in a box of seventies era
RTTY stuff I that I put aside as I run across them while sorting
through 60 years of accumulation. I hope to get to that stuff so
I can get back on the air RTTY wise. It's the AF and RF side that
is lacking at this point.
The collection started with novice ticket in 1959 to FM
repeaters to RTTY to packet radio and too many computers. Sorting
started about ten years ago and I already regret some of the items
that went to the landfill. Not that I still want them (well there
was that nice 19 supply), but I've learned that people are still
looking for the stuff.

And wasn't the DT-600 project an attempt to put the ST-5 on a single board?

The ST-5 was an excellent HF RTTY demodulator. It was featured as a constructionarticle in the ARRL handbook in the early '70's if I recall. I'm still using the oneI built back then. The ST-6 is based on the ST-5 and very similar.Steve W6SSP
