Gunnar,
I have one of those and it's performance on PSK31 is exceptional. George Heron
N2APB and Milt Cram W8NUE have done an extraordinary job with that product and
it's development just keeps continuing on.
However, it could really never be used for PSKmail BUT, the core chip may be
useable and parts of the readily available source code that handles the PSK31
I/O part of the product could be a starting platform, to build a PSKmail
hardware interface, based on the dsPIC33FJ128MC706 processor.
In adding extra modes for PSKmail, the problem may arise with the amount of
code space in the
dsPIC33 family of processors. However, external RAM can be added. consider
that even a Mailbox could be added, for when the PC is off, just like Packet
TNCs use :-)

Design of NUE-PSK Modem

PSKcore by Moe Wheatley AE4JY used in development of the modem.

This could even be a spinoff project, by the developers of the NUE-PSK modem?
Open source developers could also contribute.........
Now, in relation to the above, I have merely made suggestions and my ability to
do this kind of project is way past me, but having messed with hardware boxes
for the last 20 years and now having some 20 TNCs in my collection and still
playing with them, I feel qualified to pass my opinions on possible hardware
solutions. Please don't flame me :-)
Would be interesting to see comments, from other more experienced people.......
73,
