Some of us in EU run RTTY bit longer so we use "outdated" FSK and LSB even
without SoundBlaster.
RTTY freq is supossed to be unique HF mark tone which is the same regardless
of sideband approach.
My old IC-735 in 1980s was the first rig which showed correct CW carrier
freq including 800 Hz tone...

Subject: RE: [RTTY] Tuning Up or Down?
Hi all, especially Don and Barry..........
I think you have to consider how some of us run RTTY.
In Europe, the "norm" is to use USB on all bands for RTTY, which means
that
it is easier to tune UP the band, rather than DOWN.
It's a bit like tuning SSB, in that it is easier to tune UP on bands
higher
than 20m, and DOWN on bands lower than that.
Also, it may be pertinent to consider that there is a more natural 'stop'
point on most of the bands at the lower edge. On 20 and 15, there is the
PSK
section to sort of limit our downward loop, but the upper ends are almost
limitless (especially during the bigger contests). For me, this means I
start at 14070 (for example), and tune up as far as necessary. If I
started
at the higher end, I'd be wondering just where to start off!
Like Don, I often try and pick up the odd mult this way, and I often take
note of the call and guess from that which way to go. For me, Europeans
means I go up, and for the rest of the world, I go down a bit.
And don't forget that many Europeans run low tones, so packet spots need
to
be interpreted accordingly.
Imagine the confusion in a spot at - say - 14.085. Now, is that true MARK,
the dial readout, is he using high tones, or low? So, if I see a spot at
14.085, I start there and tune up and down until I find it.
I know there are loads of very good technical reasons for using high
tones,
but I simply can't hear them!
Anyway, just my thoughts...................................
73 for now
Phil GU0SUP
