Not every radio user appreciates a simplex repeater, since all listeners
hear every transmission twice. That gets old, really quick!
True, but there are instances where a SR makes sense. Quick deployment for low
volume comms is one. Rescue ops, public service events, etc...

The frequency response of a 2 way communications system is well within the
frequency response of one of the 8 KHz sample rate ChipCorders. The only
decisionwould beto select the longest possible message time.
The ISD1416 gets you 16 seconds, the ISD2560 gets you 60 seconds. Both of
these
The Zetron 19B Simplexor was the only simplex repeater that seemed to
work properly, since it was designed for public-safety application,
primarily for forwarding 2-tone sequential paging signals followed by a
voice message. The 19B could be set to repeat the tones and message a
certain number of
4 matches
