[RTTY] I had a reply in the contest from a fellow using cw for rtty

He is probably using a K3, Bill.

In fact, if you think back, was the "9" of your call sign slightly delayed?

The K3 has this abortion (there is no other way to describe it) where you place the rig into FSK mode and use a paddle to send RTTY.

(It won't work with a straight key, since the firmware is looking for the left and right paddle to recognize a character.  Won't work in AFSK either.)

So, a "9" will take longer time to arrive unless the guy is doing 100 WPM on his paddle.  And if you listen carefully, what you will hear is "W<beeep>9OL" because the K3 is stupid enough to wait for the 9 to finish and does not put out a diddle in the meantime.

If you remember, Phil GU0SUP mentioned some years ago hearing what sound like slow, stuttery RTTY, but copies at 45.45 baud.  That was a K3.

If I were you, I would have sent "SRI, YOU HAVE BROKEN RIG. QRZ W9OL"
