Re: [Repeater-Builder] Linking Repeaters Remotely
Make sure you Full PL BOTH tx and rxers. I have had great luck with this method. At least with the Motorolas I use as soon as the input signal is dropped, the no squelch tall...and therefore no constant keying. de KM3W --- On Tue, 11/10/09, Nate Duehr n...@natetech.com wrote: From: Nate Duehr n...@natetech.com Subject: Re: [Repeater-Builder] Linking Repeaters Remotely To: Repeater-Builder@yahoogroups.com Date: Tuesday, November 10, 2009, 5:50 AM On Nov 9, 2009, at 5:30 PM, Jerry wrote: There have been times when during events it would have been great if two different repeaters had been linked.

The repeaters in question need to be configured to transmit CTCSS *only* when carrier is present and not during the tail, as is often done when using on-channel RF links for IRLP. Matthew Kaufman
Re: [Repeater-Builder] Linking Repeaters over Internet Help
Hello Group, I am completely new to VOIP, so I need some direction. I have two repeaters with remote base ports that I would like to tie together via internet connection. Can you direct me to a page or tell me where I can get info on what equipment I need to tie audio and logic connections into the PC, and what software I need? Thanks, KC4FWC A few questions are in order. Are the computers co-located with the repeater controllers or is there a radio link from the repeater to the computer? Is this an amateur system or commercial? Which VOIP system are you considering using? Echolink (amateur only) does not have, by itself, a method of tying two EchoLink nodes together permanently. A companion program called Echotime will provide a permanent link that will automatically re-connect if it is disconnected for any reason. IRLP can work as a permanent link if you want to run Linix on both computers. I suspect a system like Skype could be configured to operate between two computers on a permanent link basis, but I am not familiar with that system. I built a direct interface from EchoLink to an RC-210 controller a year ago and it has been in service since then with no problems. I do not use one of the custom interface boards that are marketed for EchoLink and other VOIP systems, and find the DTMF decode works better in the sound card than out on the external board since you can control the audio frequency response in the sound card. In your case, you may not want any control signaling at all into the VOIP system if you are not going to allow outside connects. 73 - Jim W5ZIT Yahoo!

RE: [Repeater-Builder] Linking repeaters
We have had a multiple repeater linking system for several years that has worked flawlessly. The system is VHF (several VHF Repeaters) that is linked together using a Hub Repeater. A friend Leon N2HLT, you can see his site on the web by entering his call) has a UHF system that has about fifteen UHF repeaters. You cannot tell the difference from one of his repeaters to the other. In my case I have a 447X449 Hub Repeater. Each stand-alone repeater has a simplex link that talks to the hub. Picture the spokes of the wheel being the individual repeaters and the Hub being the HUB REPEATER that ties them all together, you can see how seamless this can be. My hub does NOT have a tail, as all the repeaters linked are not mine. In the N2HLT system Leon owns all the repeaters so he sets each individual repeater for no tail and has his Hub Repeater set with a tail, thus all the repeaters come up and go down at the same time. It doesn't get any better. Hope this helps. 73 JIM KA2AJH -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ian Sent: Monday, February 13, 2006 8:12 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Linking repeaters Hi guys .I am interested to find out the better ways to link multiple repeaters together.At the moment i am using for each link 2 data radios back to back on a site between the sites but this is a slow way to link 3 or 4 sites together using one repeater site as the central site with all the others feeding through it.One option i am looking at is to install one data radio on each of the outer sites fitted with tx and rx the central site .It works ok from the outer site i am testing to the central site but i am a bit concerned about from the central site back to the outer sites without it looping .any sugestions Yahoo!
