Allow me to disagree (slightly) on the beginnings of RTTY popularity. I would "blame" Baycom, and the old Mix DOS versions.
I used them (as well as quite few hams I know) way before PSK31 and the sound card modes appeared. Actually, after using them, I built a hardware modem that improved a LOT their performance, using both as terminals. I would say that PSK31 started the popularity of sound card modes. This is what I remember. Maybe others may have a different perspective. 73, Jose, CO2JA ---- Brian A wrote: > The advance that made RTTY so popular was the advent of sound card RTTY. > I can attest to that since I operated RTTY contests before and after > sound cards happened.
