[RTTY] RTTY Question

[WS7I]

Fast, even on a Hal ST-6000.  I think that most of these old agages were for Teletype (r) machine operation which is somewhat different than modern uses of RTTY.

There were/are all sorts of fine things like LTRS, and stuff that were necessary and special EOL sequences that are less useful anymore.

I realize that different conditions such as the presence of strong adjacent signals, QRN,?etc?can require different AGC settings, but I was wondering what some of the experienced hands recommend for a good starting point AGC for RTTY (FSK). Clearly, I use different settings for CW and SSB and sometimes use the old-timers technique of manually riding the Rf gain?control using those other modes. I use a delta loop antenna which usually provides a very good signal to noise ratio.
