Taking that psk/fsk can achieve 6
dB efficiency over on/off keying , to decode
at a similar level in a similar time is
quite an achievement !
As Albert points out, qsb caused the
most disruption, I think wspr is also overlaying
to build up a data frame , which may be
taking advantage of the qsb signature
Access to the mode is the important thing.
any (stable) station can send Opera , which
makes it the first 'new' all user data
mode since the year 'dot'
One thing that is missing , is some kind of
data server , everything is sent to the
psk-reporter system , but it a little limited
in searching and displaying
but as yet, not able to find anyone/group
to try coding one
