The main Pskmail frequency is 10.148 kHz. In Europe you will find the

I have been testing MT63 heavily for quite some time for use with psmail, but
PSK63 outperforms it,
so I am back with PSK63.
The biggest drawback (let alone the 2kHz bandwidth required) is the time it

MT63 could have a life where larger blocks are sent (e.g. for PSKftp)
