In-band 70cm Feednet VOIP Repeater

What is it ?

It is a standard FM in-band repeater.  It also provides a means of connecting the telephone system to users of typical handheld FM radios. Use of DTMF by any operator will permit a phone anywhere on the network to be connected.  If the public data network is up and running it can connect to other repeaters via the internet. Alternatively put a data link in place using radio - perhaps a point to point at 128K or use FEEDNET technoloy.

Control facilities include one time PIN codes for secure DTMF remote control, CTCSS access, Enable/Disable functions and all the usual repeater courtesy tones and timer.
