Two Station Intercom
Kit Two units employ LM386 IC's in each station. These need to be connected
using a pair of wires (about 22 or 20 gauge solid wire). You could power the remote from
the base if you run four wires. Each station has its own mike, speaker and amplifier. May
be set up as a "bug" to monitor a baby's room etc... DIY Kit 21.
