The Zetron Model 38 is a flexible repeater panel that provides individualized repeater service
to up to 60 or 68 different customer groups. It is a complete interface between a transmitter
and receiver, providing CTCSS encode/decode, repeat audio processing, and all timer
functions. It can be remote-controlled from a variety of sources. The Model 38A is equipped
with an RS-232 serial port for connection to computers and modems. An internal database
keeps track of all airtime use and, for accounting purposes, downloads into a PC. Nearly all

and 22 or 18 digital coded squelch codes.
