The >problem is one of "culture" 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.

Obviously the KPC-3 is 1200 only, >but it has software (open squelch) DCD available (just issue a command) and >has KISS mode. Did you experience problems with either of these things? 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. 73 and happy haming, Nate N8MBK --- Nathan C.
