Last weekend was the RTTY contest. All digital mode were eligible. All I heard was RTTY. I am only able to receive on 40M and 20M at the present time.
The propagation is in the sewer so I was very limited on what I could hear. I am near Seattle and the only stations I was able to copy were in 6 Land. All I was able to hear was RTTY. I did not hear any PSK. I get the impression that RTTY is still the predominant digital mode. Bob Macklin K5MYJ Seattle, Wa.

I assume that this survey for percentages, was completed after we switched from using teleprinters and RTTY or to Packet, AMTOR, or even back in the good old days when we stopped using AM and started using SSB (We used to call it 'Phone'). I suspect a lot more than 3% have open minds to evaluate different advances, or that 99% will always use the same mode. If not, then we would still be using separate Transmitters with a apark gap and Receivers with a crystal and Cats whisker, and sending each other Morse. At least in those days we didn't have Call Signs, ....
