This is a common problem Goetz. Not everyone spots the
mark frequency. Not everyone uses FSK high tones. You never
really know what is being spotted unless someone puts in the
comments section "RTTY FSK" or "RTTY AFSK". And then you still
get different frequencies because some people are using older
radios and people using low tones. There is no standard.
I don't think there's anything that can be done about it.
People are going to spot the DX by what's showing on their
dials. Some people use LSB and some even use USB for AFSK.
I like to think about it as all being part of the game, especially
in contests. If you go to the spotted the frequency and the
DX is not there then you need to look around to find the DX.
When using standard high tones and FSK and a spot comes out
and the DX is not there, it's best to tune down in frequency
approx. 2 khz first. If the spot was from someone using LSB
and high tones, by tuning down approx. 2 khz you should come
across the DX. If not, go find them the old fashioned way -
tune for them! hi

Subject: [RTTY] RTTY frequencies determination
For what it's worth...
Today I came across a striking example of nowadays confusion about RTTY
frequency determination. I was lucky to come across CE0Y/DM5TI on 10m
before the majority of the usual EU pack jumped onto him. I needed only
two calls and had my QSO. His frequency was 28084.4 mark - my FT1000MP is
set to display mark frequency for RTTY (using high tones). I spotted him
on the DB0SPC DX-cluster and kept watching his signal and QSOs. Just TWO
minutes after my spot another spot by an IZ0 station appeared on the cluster
giving his frequency as 28086.1 and another 4 mins later a well kwown OH2
RTTYer spotted him being on 28087.9 -- all the time I had copied his signal
and for sure he did NOT change his frequency!
