Hello Graham,
looking for your signals with no results until yet.
May be you can increase power for the last halve hour of transmission
(22:30 until 23:00 UTC?)

Rik,
The mfsk signal is a single tone, the other systems are sending 2 tones
,
peak levels of the systems are all the same .. as far as I can measure ,
looks like your % copy ties with last night , ? , the instant lock
of
the throb system looks to be working well ?
Each stream is about 35 watts , last night I was running 150 in
single
mode
tnx - G ..

Gary,
despite that there is no copy in MFSK4 this signal sound much stronger
than the Throbx2 and psk31 signals.
Idem on the G3YXM grabber: MFSK4 look brighter than the other 2.
Looks as if the power is not the same.

Hello Graham,
thanks for the QSO's last night.
Under current conditions (lot of QRN and QSB) ThrobX2 seemes a bit
better than
PSK31. MFSK4 wouldn't print last night.
The night before it was the same until all the sudden I had a perfect
print.
Maybe tuning / synchronisation is rather critical for MFSK4.
The bandwidth of MFSK4 seems about 150Hz, so i will not use it for
transmit.
PSK31 and ThrobX2 are well below 100Hz.
I will try to decode the signals starting 21:00 UTC.

Final set up , power ~ 30 watts per stream
same text , 60 sec repeat ..
PSK31 Cent audio 2200 Hz = 503.20k cent rf
MFSK4 Cent Audio 2000 Hz = 503,00k cent rf
ThrobX2 Cent Audio 1700 Hz = 502.70 k cent rf
Thanks for reports via email, throb, is showing well as it has 'no'
lock up time ?
