If you're going to the trouble of putting up backup RF links.... a good idea. Take a look at the Ubiquity data radios ( http://www.ubnt.com ) . Your own RF data network. Forget the public internet except for an entry point. And ditch the controllers. On the analog RF links.. If you have a lot of overlap on the simulcast transmitters, you'll need do some audio delay lines to keep everything in phase. And I'd recommend a GPS disciplined time base for the MSF repeaters. I used to maintain a couple simulcast paging systems. Simulcast with overlap is a big pain. -- Sent from my Android phone with K-9 Mail. Please excuse my brevity and typing errors.
You can't use a repeater controller with voting/simulcasting for a couple of reasons. The voter sends the RX signals to the host computer where the best one is selected and sent to the transmitters. Obviously you can't have a repeat path thru your controller and do any voting. Next reason is the RTCMs need unsquelched discriminator audio. -- Tim :wq On Aug 9, 2013, at 10:24 AM, Bob - AF6D <bob@af6d.com> wrote:

I am blessed with running my own hosting business and own my data center. At home I have business class service. I have 50 down and 5 up. I think that easily covers the voice portion. I have KVM over IP and Remote APC reboot – or I can run it here just as easily as my data center.
1. Which version of the software is best for simulcast?
The latest ACID. Always upgrade after install. see https://allstarlink.org/support.html#astupgrade
2. How about the hardware? By default I would use a Pentium 4 3GHz with 4GHz of RAM a Dell GX series desktop.
That's plenty. I'm running 4 mix client nodes, a two client simulcast node and a four client simulcast node. That's 10 RTCMs on 6 nodes. All on a single Intel Atom D25 (1Gb RAM) with ACID installed on a SSD. It runs 94% idle and 300 Mb free.
3. Should I run a SSD drive for boot-up or would a Western Digital RE4 (server class) work ok across the board?
Yep.
3. Besides simulcast for 3 nodes I’d like to share what we have as a conference node (???). Do I have enough horsepower? I have 50 down and 5 up.
Yes.
4. I'd like a private server and a public server on one PC.
No, only one server per PC is recommended. VMs are not recommended, and I might scold you if you try :-). But you can have both private and public nodes on the same server.
I would be tremendously grateful to anyone that answers these entry level questions. I don't want to make mistakes from the beginning.

Here's one way of looking at it... If all sites are able to talk to each other, then I would suggest a link repeater. Each repeater site has it's repeater and a link radio. The link radios talk to -one- link repeater. Meaning, someone keys up a repeater, the COS logic goes hi or lo (however configured) and key's the link radio, which transmits to the link repeater, which all link radios hear, and key their respective repeaters. At the site where the link repeater is, connect an Allstar node. The allstar connection hits the node, is shared by all repeaters on the link. The link repeater has to have no tones, to make it quicker in response, and no tail, to keep the repeaters from "ping-pong"'ing for eternity... What frequency should the link repeater be? Whatband has got the least amount of usage, ergo, the least amount of possible intermod? For example: So, lets say your repeater and link repeater and allstar node are on top of Mt. Wilson in SoCal. You want a shot to the northern valley area, out to Riverside/San Bernadino area, and down I-5 to somewhere between LA and San Diego. That's 5 repeaters and 3 link radios. The RC-210 has 3 inputs; Repeater Link repeater Allstar URI (Audio in, audio out, COS, PTT & Ground) North Repeater Link radio | | Repeater Hub ---------------- East Repeater & link Radio Link Repeater | | South Repeater Link Radio It's up to you as to what frequencies you want to use. You might check Radio Mobile Online (http://www.cplus.org/rmw/rmonline.html) and make sure you are meeting your RF signal path requirements. That's one way... Good luck. -Geoff/W5OMR
