A few days ago,i posted for info on a good/ez-to modify 440mHz rig for 9k6
pkt.
A ham replied about a rig from Azden that did 9k6 out of the box,but
couldn't remember

Forgive me if I seem a little skeptical about TAPR. I have my doubts
that the 900Mhz FHSS Radio will make it any farther than their last
high-profile doomed project - "packetRadio".

Right. Someone who has done some experiments with TCP/IP on amateur radio
(beyond copying the autoexec from a friend and asking for "TELNET NUMBERS"
on the BBS) knows a lot about the effects of the basic parameters.
What happens when you change the MTU, Window, initial retransmission
timeout. What is the difference between fetching two files sequentially in
one FTP session and fetching them simultaneously in two parallel sessions.
What is the difference between packets dropped by transmission errors and by
congestion. How is the routing done (what is a subnet). What is ARP
doing, and why. Etc etc etc.
Knowledge of things like that is invaluable when troubleshooting today's
IP-based networks. You may be able to learn it from a well-paid commercial
trainer who probably has never seen a network analyser himself, or you can
learn it using amateur TCP/IP.
A decade ago, you would have done that with NET or NOS, today you would use
Linux. But the result is the same.

If we look back on the current long range vision statement from TAPR,
we can see the roots of these thoughts as far back as 1988, when Pete
Eaton proposed the TAPR packetRadio project. Pete had the correct
vision and if the project had been successfully completed, no telling
how much that project would have changed the face of current amateur
radio digital communications. To date, the packetRadio was the only
