In terms of Debian dependencies, there don't seem to be any packages that
depend on the 'node' package from the hamradio section. This makes it tougher
to know what depends on the binary being named 'node'.
A problem with the name 'node' is that it's painful to web search that name to
try to find out what the project is for. :-/ This is another reason not to
like the use of such a generic name.
The hamradio 'node' program looks like it is meant to support several packet
radio protocols, either for a computer acting as a "packet radio router",
"packet radio BBS" (bulletin-board system) or possibly for a "user end-node".
I believe all of these invovle a computer being hooked up to a TNC [Terminal
Node Controller] which is then hooked up to a radio.
For an example of what a TNC looks like, see [1].
Generally packet radio involves low data rate communication. At VHF
frequencies this is generally limited to 1200 baud simplex ("simplex" means
not being able to receive during transmission, whereas "duplex" means being
able to do both simultaneously) -- so the actual throughput is always quite a
bit less than the transmission baud rate. At UHF frequencies due to wider
channels the packet can be a bit faster -- up to 9600 baud. [At SHF and
higher frequencies data rates can be faster
Some TNCs also support other things such as slow scan TV reception, Morse
Code, RTTY, "packet email" (stored in the TNC momory, blinking light to
indicate a message is waiting), packet message forwarding (so that a message
from New York eventually is received in some other part of the country, all
over radio), etc.
Due to low data rates, packet radio isn't as popular today as it was in the
1990's, when telephone modems that were typically in use were also slow. [The
early 90's is when I was doing packet radio.]
