The 224.56 Packet Repeater
First in the Pacific Northwest!
The 224.56 repeater is located on Gold Mountain, west
of Bremerton, Washington. Thanks to TV Station KCPQ for allowing us to
place our repeater in their transmitter building. The antenna is mounted to
their transmitter building at an approximate elevation
of 1500' (450m) above sea level.
The repeater was built in the early '80's from a Midland 13-509 mobile
radio, with the addition of an AEA PK-90 to act as the identifier. In the
early 90's we added a home brew regenerator and an all-digital design of the
True-DCD circuit to improve performance. Until
the regenerator was added, the repeater would pass voice traffic, however
with the level of packet traffic that the repeater was loaded with most of
the time, this was not normally an effective (or fun) voice repeater!
The repeater was a popular local lan for AX.25 (unenhanced) traffic until
TCP/IP became popular. Since then, the 224.56 repeater has been very
popular for "backbone" activities, where higher speed systems are not
available, and for serving those users not in range of one of the several
simplex LAN's where TCP/IP is used.
The owners of the 224.56 repeater plan to replace the existing system with
a 9600 bps packet repeater in the near future. Watch the SEATCP mail list
(seen elsewhere on this web site) for up to date information.
