[RTTY] TTL from the ST-6000

[Jay WS7I]

Tom-

I assume you have the ST-6000 schematic.  If not hollar.

Figure 5.1 ST-6000 Block Diagram.

Middle of the bottom.  J3-9 goes to RQS Pin7 DB9.  Above this that line 
goes to a spot between 2 ops.  I show a Diode added in the line J3-9.

On the Aux Connector J3 Pin 3 (Pre-autostart Data) goes to PK232 See RXR 
in PK232 manual.

J3-10 is hooked to J3-4 and J3-14 is hooked to J3-13

RS-232 Out is J5-1
RS-232 IN is   J5-4

Think this is somewhere in a old RTTY Journal.  The stuff that K0BX has 
for the ST-8000 on his web page

If I remember right all I had to do was change a few jumpers on the 15 pin accessory plug.  I then took the output from one of the 3 pin connectors and I had a diode bridge between the two pins.  That was all there was too it.  I have looked through the manual of the ST-6000 but have not even seen a reference to TTL.
