Thanks John,
Its printing ok off air locally , but I am seeing some 'hash' at about -40
db
on the spectrum plot .. this im not sure of ... just checked with digipan
as a tone generator imd's are well down so its not a tx problem as
such .. may be some noise in the exciter audio path , the gains
up quite high for a mic at the moment .. I will try setting it back to
0dBm .. that may quieten it a little .. but not tonight ..
tnx- G ..

Subject: LF: G0NBD difficult to decode
Hello LF,
I'm seeing really strong signals from G0NBD, and it was decoding
earlier, but now I seem to be unable to get a decode from what should
be a good string (positive S/N ratio) signal.
I see at WSPRnet that Graham is not being received by quite as many
stations as I'd have expected. I wonder if there's some strangeness
with the soundcard sample rates at either the TX or RX end? I've read
some reports that strong signals often don't decode, when weak ones are
fine, and sample rates are involved?
Graham, the signal is making it here, bright red on the waterfall, but
the last 3 periods have failed to decode.
John
