[GreenKeys] FSK Keyer Information Request

[Russmill47 at aol.com]

I'm currently working to get back on the air after a long lapse in RTTY  
operation.  My ST-6 TU and M28ASRs are fine.  I seem to have lost my  FSK Keyer 
over the years.  Since my transmitter is CW / AM only, AFSK is  not an option. 
 
Looking back to RTTY Journal from September 1967, in Irv  Hoff's Mainline 
TT/L-2 article, I see that I need some basic parts, such as  a RFC, a diode and 
an NPO type miniature ceramic trimmer. It looks like I  can locate similar 
parts from Newark. But before I do, what do folks who wish to  stay with FSK use 
for an FSK Keyer today?  Is there anything new that  I should know that works 
well with the ST-6?  Any and all advice is  appreciated.
