I do not have any idea about building the transceiver, sorry.
Respect to the TNC, I think it is like a modem that connects your computer
to your transceiver. ( I have never seen a TNC so I can not tell you
details) I have read that you just plug it in a serial port like
Com1, com2 or /dev/cua0, /dev/cua1.
Respect to the Amateur Radio packet software I know 2 options:
1) a "little" program named "Ka9q" or JNOS, apparently an Amateur coded
"ka9q" invented this program. It runs on MS-DOS and it is a router program
with integrated client and server for telnet, ftp, mail, etc. I downloaded a
copy of this program and it runs ok. I have used it for routing TCP IP
between ethernet card and serial ports with a modem, but according to the
documentation it can also route with ax25 packet switching.
2) you have to compile your Linux kernel to include ax25 protocol and
support for TNCs.
I know that in United States there are BBS with access for Amateur Radio.
For detailed information get the Linux Ham Radio howto from :
ftp://sunsite.unc.edu
