2075 - W9SH - Johns Creek, Georgia, USA

Node 2075 is connected to a simplex UHF-FM transceiver on 446.100 with 77.0 Hz CTCSS encode and decode. The computer is an IBM Netvista P3-866 machine with a USB interface to the radio.

It includes a hardware crosslink to another computer running IRLP node 4420. The crosslink hardware combines and routes audio and PTT/COR signals using summing node op amp mixers and diode-transistor logic.

This computer is also my home Asterisk PBX server with a SIP connection to the public telephone network via Axvoice. It also handles incoming Free World Dialup calls. Through Asterisk with app_rpt I can call in from my Sprint PCS cellphone and connect to either the AllStar or IRLP network.
