Thank you for taking the time to reply. I appreciate it. I will reply inline for clarity. ----- Hi Wayne, I re-read some earlier messages in this and related threads, to better understand your systems design goals. And, the earlier threads have left me with even more questions. From what I read, you've got a substantially complex system planned. It's going to take some expert level work with radios and computer networking to get setup, no matter what solution you choose. I believe it's all quite do-able with AllStar, but, is well beyond the scope of this mailing list. To address your specific questions, below: 1) Selling RC-210's should be simple enough (E-bay?). [ I thought I saw something about not reselling them. At a minimum they have to buy the software. ] 2) Since you've got a private network and a public network involved, that's fine. But, this is a somewhat complex networking task. You'll need to get everything "talking together." I'm suspecting you'll want to implement some VPN's (Virtual Private Networks) to accomplish this. I use OpenVPN under Linux. It works great. BTW, I'm not sure RTCM's are the best solution. And, you don't need a Windows box at each site. [ My intent is to vote/simulcast two of three sites and bring in a third site on a different pair. Site 1-2 require a RTCM and Site 3 a URI, correct? ][ I've never done anything with a VPN and don't know how to implement it. I thought that given to IP's by my site vendor the RTCM's would talk on the same network, albeit a VLAN. But how do I access it to control? How can I bridge the public IP I have been given with the private VLAN? ] 2) There is an small, unavoidable audio delay from audio input to output with AllStar. This is typical with any VoIP radio system, including full digital systems like D-Star and DMR, etc. This delay isn't like the delay found in traditional analog linked repeater systems, however. In older linked systems, you'd have to hold the PTT down for a second or so to allow all the transmitters to come on-line or you'd loose that initial audio. AllStar digitally buffers the audio during propagation from any member receiver to all member transmitters. So, the audio could be buffered and delayed as much as several hundred milliseconds (a big network!). But, not typically lost. [ I can deal with the delay. ] 3) As for persistent kerkhunkers and other issues, no hardware is going to solve that. That is an etiquette problem. Over time, (most) users can be trained to behave. Yes, I know you're saying: "Yeah, right. I hear you." But, I help with several wide-coverage repeater systems, so, I've been there, too. [ Jammer's that kerchunk to annoy cannot be trained. ] 4) Yes, you can hook various systems together (WX radios, remote bases, etc.) into a single network quite easily with AllStar. But, it will likely take some complex scripting and networking to do, just like with any controller. I don't fully understand the scope of what you're wanting and as I mentioned above, trying to build the system here is beyond the scope of this mailing list. [ I don't mean to be rude but this should be an easy task to do and understand. We are an ECOMM repeater(s) and each site needs a WX receiver on it. The commercial WX receivers have audio, COR, PTT and COS. I don't see how this is beyond the scope of the mailing list. Can I connect such a device using a URI? ] I understand your overwhelm! I would recommend getting started in small steps, if possible. First, only put up a test repeater or remote base with AllStar and get a grasp of how that is setup. Then, add a second AllStar box and network the two together--take small steps. Now, if that's not a possibility--meaning you've got to have the whole system on-line "like tomorrow", you probably need to locate some expert help ASAP; due to the big learning curve with this (or any other) complex VoIP system. [ I have plenty of time. I don't see our needs as complex at all. Two voted/simulcast repeaters and a third repeater linked in. A WX receiver and an Earthquake Alarm receiver on each repeater. ] Anyway, I hope this helps some. 73, David KB4FXC
