[RTTY] Field Day Digital: PSK vs RTTY

[Mike N8MR]

Hello All, 

For the 4th year in a row, our local amateur radio club set up a separate digital station for Field Day. We've heard that RTTY is the most popular digital mode for Field Day, but this year, we found far more PSK31 signals than RTTY signals. We listened for PSK31 at x.070 and RTTY from x.080 to x.100 on 40, 20 and 15 Meters. 

Is PSK31 the more popular digital mode for Field Day? 

What is a good average total QSO count for a digital station on Field Day? 

73,
Mike, N8MR
