Hi again Jim With your thinking below .My remote private site should work in the same sort of way as what you are suggesting except while s2 has a signal on it it sends this signal to both s2 users and back to s1 repeater at the same time.In return the signal works the same as your first 3-5 lines below.I only require one link radio on the remote sites and not one at each end of the link .However with our open we have a separate link repeater paired with the s1 (explained better in my response to skip) so the link system works at the same time as the central site repeater.In the open system we don't link the TX frequencies directly from site to site .I.e.(s1tx to s2rx)(s2tx to s1rx) due to a error in frequency allocation,which will be fixed and which we expect to link directly with our private system as we wont get the sites frequencies licensed so close together next time Thank You, Ian Wells, Kerinvale Comaudio, 361 Camboon Road.Biloela.4715 www.kerinvalecomaudio.com.au -------Original Message------- From: Jim Brown Date: 4/01/2008 8:25:48 AM To: [email protected] Subject: Re: [Repeater-Builder] Linking two shared repeaters Ian, here is my thinking. When site 1 has a signal on the repeater input, the signal from site 2 is blocked because of the circuit that gives precedence to the local site repeater receiver. When a site 1 user unkeys, there will be no CTCSS tone coming back from site 2 to key the site 1 repeater. The combination of the precedence circuit and CTCSS requirement for both repeaters keeps the system from locking up. The same circuit would be required between the receivers at site 2 as in site 1. And both repeaters would have to be configured to only transmit a CTCSS tone when a user keys the input, not during the squelch tail.
