I spent a few minutes on 75 baud RTTY on 20 meters very late Friday night in
the contest and wanted to take advantage of the good
propagation to EU that occurred just past their sunrise. The SFI, A and K
index were good but changed quickly on Saturday. I
worked several EU stations and a couple USA - probably 14 in all. There wasn't
much activity. I was busy the rest of the weekend
so couldn't get on.
I find 75 baud RTTY contesting a lot of fun. I had some trouble working a
couple of the weaker EU stations, but overall my
experience with 75 baud RTTY contesting (mainly in BARTG75) has been good. The
trick for me is to run HIGH POWER and send longer
than normal buffers which may defeat the purpose of running a higher baud rate,
but it seems to work better for me.
I actually prefer 75 baud RTTY contesting when conditions are optimum, but for
overall RTTY contesting under all conditions, 45.45
baud is still best.

I put an hour into the contest, RTTY 75 only. It was the first time I had tried
AFSK using the Icom Pro 3. It worked 'okay' but if I
was going to get serious about it I would need to rewire the cables in order to
use the data jack on the back of the transceiver. I
hacked together an AFSK solution using the front panel mic input. (The i-Mate
accessory provides an 1/8" jack for a secondary audio
source for TX.)
I'm a hardcore FSK addict and there isn't a good (FSK) solution for MMTTY
driven beyond 45 baud. In other 75 baud events I have used
my Kantronics KAM Plus to TX at 75 and I receive using MMTTY. In that
configuration I can use the Twin Peak Filters in the Icom if
I want.
This weekend I setup N1MM / MMTTY so I could receive both 45 and 75 bauds
simultaneously. That worked well.
I worked 11 stations total, 4 stateside and the other 7 were EU. I ran low
power. K7VC was my first contact. I was working on
another project in the shack and left my radio tuned to his signal to see the
level of activity. Not much! I worked 1, 3, 5, and 7
USA call areas and OH, HA, PA, OE, UR, DJ, and EB countries.
The band conditions were not great so I resent my report several times to avoid
AGN? responses. It kind of defeated the rate
increase at the higher speed, but it's still fun to see the reports zip across
the screen.
