RTCM,s are $280 and you could put together a BBB system for around $150 or alot less if you want to mod a USB FOB. Of course this is minus radio in both cases.<br><br>I have no experience with an RTCM. I think it has many nice features but many that the average person would never use.<br><br>The upside to the RTCM is you would have one server that you could configure to do what you want rather than handling each individual BBB server. The end product would be the same but the administration would be different. You could administer remote BBB nodes via SSH/SCP very nicely. The downside of the one server multi RTCM is that if that server or its connection goes down the whole system is hosed. The RTCM's while maintaining local control would not be connected to anywhere.<br><br>The BBB approach would be a stand alone server capable of anything an Allstar system could do. It is also very reliable and the new code that is coming out in a few days will be rock solid and suitable for remote locations.<br><br>We have a basically BBB network here in PA/NJ with a central PC hub that they all connect to with mostly permanent connections. If the hub or internet connections to the hub goes down it will reconnect. The hub uses a startup macro to establish certain key connections. I find it is best to have the various nodes connected to the hub use permanent connections to the hub with a startup macro. If anything goes down it will come back up and reconnect will take place. <br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">From: tim.sawyer@mac.com<br>Date: Sun, 28 Sep 2014 14:00:00 -0700<br>To: N1XBM@amsat.org<br>CC: app_rpt-users@ohnosec.org<br>Subject: Re: [App_rpt-users] Multiple nodes<br><br>There are a few ways to do what you want — that is permanently tie multiple repeaters together — if I understand your question.<div><br></div><div>First, permanent connections are not as permanent as you might expect. If the computer that initiated the permanent connections goes down the connection will not reestablish. However you can have a startup macro make the connection as Asterisk starts. Also, there seems to be some intermittent bug, which I’ve never pinned down, where permanent connections won’t reestablish with out forcing a disconnect first. <br><div><br></div><div>Second way is with RTCMs. They are a whole lot easier to deploy and way more reliable than a bunch of USB type nodes, with the trade off in expense. Although by the time you buy a BBB and a URI you’re getting close to the expense of an RTCM. Of course you can go with a cheep sound dongle and an eBay used thin client PC. It’s the ‘ol time/money/reliability trade off. I strongly recommend the RTCM approach. </div><div><div><br></div></div><div>And a third option is called app_radbridge. If you don’t want to buy RTCMs this is probably the way to go. I’ve never tried to use it. The only documentation I am aware of is in the source which is reproduced here. </div><div><div><div><span style="font-family:Monaco;font-size:12px;"><br></span></div><div><span style="font-family:Monaco;font-size:12px;">/* This application is intended to provide a generic "bridging"</span></div><div><div style="font-size:12px;font-family:Monaco;"> functionality for radio-oriented Asterisk channels.</div><div style="font-size:12px;font-family:Monaco;min-height:16px;"><br></div><div style="font-size:12px;font-family:Monaco;"> The idea here is that certain radio applications lend themselves</div><div style="font-size:12px;font-family:Monaco;"> to needing a "generic" (passes audio and tx/rx keying completely</div><div style="font-size:12px;font-family:Monaco;"> transparently) to and from two or more endpoints.</div><div style="font-size:12px;font-family:Monaco;min-height:16px;"><br></div><div style="font-size:12px;font-family:Monaco;"> An example of such an appication might be replacing (or providing</div><div style="font-size:12px;font-family:Monaco;"> equivlent new functionaliy of) one or more full-duplex UHF control</div><div style="font-size:12px;font-family:Monaco;"> links with an IP-based one(s).</div><div style="font-size:12px;font-family:Monaco;min-height:16px;"><br></div><div style="font-size:12px;font-family:Monaco;"> app_radbridge allows multiple instances of radio-oriented channels</div><div style="font-size:12px;font-family:Monaco;"> transparently "bridged" together.</div><div style="font-size:12px;font-family:Monaco;min-height:16px;"><br></div><div style="font-size:12px;font-family:Monaco;"> The config file (radbridge.conf) allows specification of each</div><div style="font-size:12px;font-family:Monaco;"> "bridging" instance and what radio-oriented Asterisk channels</div><div style="font-size:12px;font-family:Monaco;"> are to be associated with it.
