[GreenKeys] Questions Re: Model 15 TTY

[Duncan Brown]

Bob,

If your ST-6 is working, it has a loop supply built in. It should put 
out 120VDC and be current limited to 60 ma. by the big rheostat on the 
rear panel.

*Before you power up the ST-6*, open it up and check that the boards are 
all plugged in securely (they have a habit of loosening up and even 
falling out). See http://www.navy-radio.com/rtty/hal.htm for a manual.
See http://rtty.com/development/tu/index.html for general information on 
the ST-6.


have fun,

Duncan
