[MRCG] KY-32/GRT and TCK Transmitters running FSK

[Bill Orr]

So I’m getting ready to pickup an TCK-7 and noticed online that there was an addon box KY-32/GRT to run RTTY anyone have info on what this box is? I assume its some sort of keyer that hooks into the oscillator circuit somehow to shift its frequency none of the TCK manuals I have mention anything about running RTTY or KY-32/GRT.
