Over the past 6 months or so, I have used most of
these modes on hf, and have found that Olivia runs best, followed by
MFSK.
I'm looking forward to the possible inclusion of
DominoEX on Mix W, which might make it more effective than the stand-alone
software
available now. The same goes for MT63, which I used
alot, too.
I think it's great how these modes have
evolved..... the next big breakthru will be an ARQ mode......
Think the frequencies are fine, have been using
Olivia from 14074 to 14080 lately with better results than fighting with the
pactor 3 stations
on 14107.5

Subject: [digitalradio] Should some
digital modes be considered obsolete?
While I have used MFSK16 a lot in the past, it seems that
Olivia has
supplanted it, even though Olivia is often a much wider signal
and
requires fairly robust settings to equal MFSK16 under difficult
conditions. But from what I see on the print, a number of digitally
active hams feel that Olivia is the better choice.
But what about
the other modes mentioned below? Do any of you use these
modes?
Other than just trying them out via the sound card to see
how they
sound, I have not knowingly heard or worked MFSK8, Throb, ThrobX
or
DominoF.
Are there conditions on HF that warrant the use of
these modes?
Or should they be considered replaced by the newer
modes?
Just having a lot of modes is not really the best thing in the
long run.
What makes a difference to me is having the right mode for the
right
conditions.
This is especially true if you need high speed
with very good HF condx
vs. some kind of speed that will get through
really difficult conditions
such as the kind of conditions that stops
Pactor signals from working,
but still allows some of the digital sound
card modes to keep working
even though they are magnitudes slower under
good condx.
