Hi Hugh,
I checked the spots and there is no drift on your
signal, timing seems ok for me ( mostly 0.3 sec difference). No Idea why I am
the only one.

Betreff: LF: SSB
modulation for WSPR
So far the only person to decode my WSPR transmissions
is Joe, DF2JP.
I made a drive unit for 136kHz to utilise 4 different
methods of
modulation including quadrature switching for SSB.
Having just
discovered that a fault caused the I and Q channels to
be somewhat
different I wondered what the effect would be and why
Joe was the only
one to decode it?
The carrier frequency is never more than 0.8Hz out,
time is spot on via
GMT (UTC) and the sound card is perfectly accurate so
receive decoding
is good.
Hugh, M0DSZ.
(P.S. I have no intention of signing up to
Yahoo).
