Packet radio is computers talking to computers using radio rather than phone lines. A special
modem called a Terminal Node Controller (or TNC for short) is used to interface a computer to a
ham radio. A network of packet radio stations is setup so a user can connect to stations far away
by using other packet stations in between. Packet radio BBS's are common. They use a store and
forward concept to get mail to it's destination. Any given BBS therefore only needs to make
connections with its direct neighbors.
Please not that the packet system is no longer active. I keep these pages here for historical reference for your viewing pleasure.
The WN7C Packet node and bbs is located in Mt. Gilead, Ohio, 40 miles north of Columbus
Ohio. User frequencies are 145.070MHZ 1200 baud and 145.520MHZ 1200 baud. There are
also several other ports operating at 4800 baud and 9600 baud to interconnect the system with
The BBS computer in use is a 386dx40 with 20 meg of ram. It is running MSYS BBS software under windows 95. This computer handles the user ports.
The Node computer in use is a 386sx33 with 1 meg of ram. It is running BPQ Node software. This
computer handles all the high speed networking ports.
