I did something of the sort using FRS radios on a hunting lease where terrain did not allow everyone to communicate with each other. I tied the audio out put of one to the mic input of the other and vice versa.
They were set in VOX mode and each radio was set to a different channel. One group set their radios on one channel and the other used the other channel. The "repeater" was seperated by about 3' vertically. It was simple and cheesy but it worked. -----Original Message----- >From: Greg <[EMAIL PROTECTED]> >Sent: Jan 30, 2007 7:26 AM >To: Repeater-Builder@yahoogroups.com >Subject: Re: [Repeater-Builder] Hand Held radios as repeaters > >Thanks Eric, >It will be for experimental purposes mainly with a fairly low duty cycle.
