I've only observed one RTTY qso in that time but then again I'm using a modest dipole.
Watch the Contest Calendar for the next big RTTY Contest.
You'll be amazed at the number of signals and countries you'll hear...with the modest dipole.
I once worked 72 countries in the first 24 hours of a RTTY contest,
using just a multiband vertical. But that was some years ago when condx
were much better.
To the original poster:
Your DX PSK-31 QSO's can be used towards DXCC RTTY.
