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.

Quoting Graham <[email protected]>:
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 ?
Graham
