N5FDL Exclusively Uses and Recommends ARCOM Controllers
Every N5FDL repeater is built around an ARCOM RC-210 repeater controller. These three-port controllers are big enough to do the job in our system and can be expanded (a bit) if needed. The controllers are highly flexible, include built-in Digital Voice Recorder (DVR) and playback features. Price is $350-$450 with case and real-time clock.
ARCOM offers Windows software for programming the controller. It greatly simplifies the steps necessary to make an RC-210 work as required.
The company provides excellent technical support and has a very active Yahoo group.
The RC-210 is available either as a kit or built-and-tested. Optional phone patch, audio delay and real-time clock add-ons are available, as is a 1U rack mount case.
We have had excellent luck with these controllers and have standardized on them for all the machines we work with.
