Yuri,
I do not want to storm open doors,
so will You, please, share, some practical hints for PSK63:
1. Which short key lets You jump forth and back between the two SpotLists?
2. What S/N ratio do You use while running, so that Auto CQ is not stopped?
3. Do You use RTTY mode or DIGU with FLEX-6400 for PSK63?
4. What is Your RX filter width for PSK63 if it is DIGU mode?
I would really appreciate Your masterly feedback...
Best regards,
Alec
