Mr. Olson's comments on "culture" are right on. However there's another
facet in point-to-point that needs addressing. That's routing cues.
With traffic intended for an amateur station, we have the White Pages
service to tell us their home BBS. There are also hierarchal addresses
that *look* like internet domain names but are *not*. These are actually
*routing cues* for the BBS system. And then there are the real domain
names used by TCP/IP stations. These are *not* routing cues. Instead
they are pointers to addresses in a DNS server. All of these methods
can, however, resolve to a specific destination.
With NTS traffic, generally addressed to a non-amateur, none of the
above systems apply. Routing cues are supplied by one of two methods.
Either by zipcode, or by NTSXX where XX is a state code. These alternate
addressing methods often point to different destination BBSs.
Once it gets there, the message then languishes until a traffic
handler picks it up and delivers it, usually by local phone call,
to the addressee. Routing is a problem, but destination servicing
is the main bottleneck.

iYes the KPC-3 does have KISS mode however I prefer to run a KISS only EPROM
so I don't have to put it in KISS everytime I want to use it. Also the DCD
detection provided by the TAPR DCD mod is IMHO far superior to that of the
KPC-3's software DCD.
Then again maybe I'm just picky.
