Phase-shift keying

And that's, that's what they're saying it is.

However, when I asked the question, you know, "What makes JTTY better than, let's say, PSK31?" And I got quite a screen full of, uh, items.

Uh, the modulation type is 4GSK versus the phase shift keying of, uh, PSK, the BPSK and the QPSK, if you remember.

And the bandwidth, about 125 k- uh, hertz instead of 31 hertz, even though they had different sizes of the BSKs and PSKs.

One of them was 125, I think.

Um, and the speed, uh, PSK actually is a little bit faster.

I'm comparing, uh, to 31, PSK31.

Uh, 50 words per minute, 31 baud versus a 31 per minute on JTTY.
