Op8 is very similar to QRSS3 in effectiveness, except that you can
interpret an 'M' signal when Opera cannot.
LOL. Yes, it obviously looks like that. Anyway, nice game with all the
features i must admit.
I got two decodes at marginal level, which I would expect as
Op8=QRSS3, and my QRSS120 has been received well at times with
Haldor.
I have been saying for years that we may be going wrong by aiming for
slower and slower modes on LF (not VLF which is different), because
the QSB destroys the gain of the narrower bandwidth.
Agreed. Anyway the 424 uHz tests by DF6NM, 4X1RF and some US stns have
been positive and interesting. It's always the question if you want a
QSO or a full callsign to be copied or just leaving a faint trace...
Instead, it may
be useful to exploit short-term peaks at faster speeds. It is, of
course, a compromise between speed.and signa/noise.
Yes, or instead rising the power. At least by this level the average
local QRM caused by all the electronic stuff (whose manufacturers do not
at all care about radio amateurs!) rises the noise background over the
years!
