Hi all,

I’m still working on getting set up for RTTY at my QTH. I am planning to start with a glass tty set up, then get my M28s wired into the set up. I am using a 1980’s vintage Harris modem that converts RS-232 to audio tones and vice versa. The way it is setup, when I type, I hear the mark/space transitions for each character. However, no audio is produced between the characters. Meaning no mark tone would be transmitted between characters.

Question: How big of a deal is this when doing RTTY? I know that some TUs might not recognize that there is neither a space nor a mark audio frequency present, and may produce garbage on the screen/printer. Or, do most operators use a mark-hold function while receiving that would prevent (reduce) the garbage?

Bottom line, should I go with what I have? Or work hard to make sure a mark tone is present at all times between characters?
