Hi Mike and readers,
Sorry, sometimes I get callsigns backward, don't know why.
Yup, the PK-232 is a common TNC and has a digipeat function since it's
commonly used on VHF. No, a node and a digi are two completely different
things. First, a node is software driven and a digi is hardware driven.
That's why a digi is a stand alone device and doesn't need the computer
to operate. You must connect to a node, then connect out of it, two
connections, that is two links minimum. The number of links increases
proportionately with the number of nodes connected to form the chain to
the destination and they're all connected, one to the other, network
fashion. You don't connect to a digi, it's a repeater like any other.
Digis aren't connected together either as nodes are, they simply repeat
one to another down the line to the destination. When you use nodes the
software remembers the destination path so all you have to do is connect,
then type <c (callsign)> and the network does the rest. When you use
digis, YOU remember the destination path and type it in when you connect
with the destination station. It goes like <c callsign D v callsign digi1
v callsign digi2 v callsign digi3> and so on down the line. Of course
things can get really slow if you use too many digis, best to go as
directly as possible so you have to map out the area, know who is over
the horizon so to speak.
Oh, something worth mentioning where land line links come in handy and in
some cases indespensible. APRS used to be exclusively digis which lent
such a high degree of flexibility to the system. It grew at such a
phenomenal rate and spread around the world which led to systemwide
failure, just got too big to function like a very fat person. Considering
the size of the US it would take days to fill in the map or get one of
those "one liners", those very short one line messages only halfway
across, nearly a week for the full passage. Internet linking fixed tis up
real quick and now the system works better than ever, but still you can't
link a moving vehicle to the Internet without special, non Amateur
considerations. (;->) The same can be said about DC clusters, real time
operation can only be achieved within the cluster without Internet
linking clusters together. There is no way the packet forwarding system
can keep up over great distances, by the time I receive a post from the
Midwest by radio the DX would be long gone. In the case where there is a
"need for speed" Internet linking is ideal and I support it believe it or
not. On the other hand, where there is no need, can the speed and use
Amateur RADIO! (;->)
Oh, pardon the typo, read "DX clusters".
I called AGWPE land line lid software because like Winpack it's designed
to operate over the Internet. Of course they can operate radio but most
frequently the lids get the whole thing confused and we end up with a
bunch of gateways. One thing I find most frustrating around NJ is all the
gateways duplicating each other with overlapping coverage, a whole sea of
gateways spread around the lower portion of 2M originally intended for FM
simplex and experimental modes. It's a huge waste of spectrum we would be
better off without if only they were coordinated and the duplicates
eliminated. Well, everyone wants an "ego box" with his callsign up in
lights, be it a voice repeater, gateway, IRLP or EchoLink node. YUK!
Frankly I'm happy with my little old digipeater spitting out it's beacon
every ten minutes, MY little ego box. (;->) OK, it's a USEFUL ego box
providing repeater and propagation beacon service, so there! (;->)
"AAAARRRRGGGGHHHH!!!! What is it?"
A sound made in frustration, pronounce it loudly like you're angry and
you'll understand. (;->)
Uh, while I understand your parody of my tag line, don't you think it
counterproductive speaking with two mouths? A true explanation of using
Internet linking only when needed and using radio as the primary carrier
makes for a rather big and confusing message to be tagged on. That's why
mine is short and sweet, expressing my primary intent. You have to keep
tags simple for simple minds and discussion for discussions like we have
here. That way they understand the difference, hopefully.
OH! Almost forgot, no, I won't be operating CQWW or anything else on HF
this time around. Living conditions disallow HF antennas, no place even
for a wire from here to there. I used to operate from other stations once
in a while but haven't had the opportunity lately. I listen a lot on my
indoor wire but being an SWL just isn't the same. (:-<)
