[RTTY] FREQUENCY IN USE BY ... (JT65/JT9)

The RSGB run a RTTY and PSK 80m contest on a monthly basis. It runs for 2.5
hours in the evenings. To score well both modes need to be used as points
are normalised for each mode and then added together to work out the final
score. 

All serious contesters complained about PSK31 being slow, which it is. It is
slower to make QSOs with than RTTY. However note it is a PSK contest not a
PSK31 contest so now a faster speed is used PSK63 and that makes QSOs at a
similar rate to RTTY.

PSK per se is not a problem it is the speed at which it is used.

I don't think anyone in the RTTY contesting community has il will for the
PSK guys.  But on the same token, if the PSK guys want to have more
contesting activity, and draw a bigger crowd, they need to organize and
promote the things that make contesting fun - which includes a focus on
Q-rate.

To my thinking, the contest organizers are the ones who will need to do this
- not a bunch of RTTY guys coming to the PSK party and telling them how it's
supposed to be done.  But I don't think it's going to happen.  I talk to a
lot of guys in our club who are into PSK about getting on RTTY.  For the
most part, they are not interested in the mode, and even less are interested
in the contesting aspect.  But that may be just a small window and I admit
it's not at all intended to be a proxy for the greater PSK community at
large.

I agree that too many of the PSK31 operators are unskilled in contesting. 
That may be because they haven't had the opportunity to learn the
techniques. Possibly, if more contests had a PSK category, along with an
RTTY category, they would eventually learn. If you didn't want to be slowed
down by them, you could stay in the RTTY band and let them plod along. 
Remember, we are an older mode with years of experience. Given time, maybe
they also would have a PSK-Contesting forum where they could gripe about too
many characters in an exchange.

Wouldn't it better if we were to mentor our fellow Amateur Radio citizens,
rather than calling them "those guys," as if they were members of some rival
gang across town?

BTW, when I look in my log, I can spot many callsigns that I have worked
with the mode of RTTY, PSK31 & JT65 on different dates. So I know that many
of you do operate multiple modes. I work DX and even ragchew, when I am not
contesting. Hope to see y'all in my log sometime in any mode.
