Re: [Repeater-Builder] RE AGM batteries
There should be a place on the battery from a small drain tube so that if it vents it can be directed outside the battery box... On 8/9/10, Doug Dickinson dougd...@yahoo.com wrote: Just to clarify what was said before about AGM batteries, when an AGM battery vents, it's because something is wrong. Either it was charged too fast or discharged too fast or it is in a condition called thermal runaway, which occurs when a battery is overheated. In an ordinary scenario, it is just fine. I would place it in a cabinet in most cases. In some instances though, it would make sense to have a separate container vented to the outside. It all depends on your appetite for risk, and how you are using and controlling the battery. Cell carriers will place them in the same cabinet as some very expensive electronics, When there is need for a lot of them (AGM batteries), and a separate cabinet makes sense.
Re: [Repeater-Builder] AGM Batteries
Agreed... On the other hand as long as the charging voltage is not too high general venting should not be a problem. On Sat, Aug 7, 2010 at 4:20 PM, Ralph S.

It can run with conferences or not or you can build your own conference bridge. It uses sub 10.00 USB dongles for the radio interface. AllStarLink etc are just conference bridges and registries offering packaged install distros but the underlying install software is an app_rpt extension. You can install it on any linux distro or use ready made versions. I suspect it will do what you want... but there is a learning curve... I am currently playing with a distro called Limey Linux which is made for embedded Flash type installs.. like SD cards or CF cards.. 128mb size area. I am using a D945GCLF motherboard.. sub 100 with cpu and ram.. In any case the application is probably very suitable for your needs.. and free There is also are companies that produce apps like XIPAR... there are free parts and chargeable parts.. but looks like they offer the bridge software too.. If you want to stick with telephony the app_rpt system will work with FXS,FXO and similar cards for radio interfaces.. but the usb dongles are capable of handling much lower level interface to the radio at baseband..and do ctcss etc in the DSP They are all based on the connectivity of asterisk so sounds like you are familiar with that part.

OK, I understand the commercial product line and the need for small business solutions (). Raytheon NXU etc. What about the amateur service trying to break into the ROIP solution? I built a P25 repeater for amateur service just because the technology is there. It works and is cheaper than buying a complete P25 commercial repeater. Now I want to build a ROIP interface similar to IRLP and Echolink without a central server owned by someone else. I have the dedicated fiber infrastructure (10GB backbone) in place I can utilize for ROIP. What I need is a schematic so I can build my own ROIP cards for PC or a cheap already built card available on ebay. There must be a Asterisk and cheap card solution out there. Anybody already done this? I have an Asterisk PBX server already built and working. Anybody set up Asterisk for ROIP and what card(s) did you use? I see then for $159 on ebay but I already have MANY parts and can build them cheaper, but still need a schematic or pre-built card. If not, how about starting a discussion to do this? My goal is to link several repeaters via ROIP other than echolink or IRLP. Thanks! Neil WA5JXY

I know on the B52s that they turn on ECM (Electronic Counter Measures) when leaving the coast and when returning. ECM doesn't transmit unless it's attempting to jam incoming bad things. Otherwise, ECM is a passive system, listening. If you'd said they turn on active RADAR, the comment would have made sense, and I'd agree with that. Probably a defensive flying endeavour to help them see and avoid the insane amounts of traffic at the coast. Always a nice option for the PLT if you have active radar and can see other people trying to run into you, but they're talking to ATC also... just a secondary information source. More electronic eyeballs outside the cockpit... Ironically, this indirectly means that UHF Amateur receivers apparently are an excellent way to know when certain military RADAR systems go active, and that in and of itself is a bit of an intelligence coup, if you think about it. Buy an HT if you're wondering if the big iron is up and active... :-) Amateurs on the coasts near Naval bases regularly receive unintentional interference from Navy RADAR, inland it's usually aircraft (think about the ERP/power requirements to hear OFF-FREQUENCY UHF noise on your Amateur Repeater... whew... those boys have some power on board!) or fixed installations, and can be DF'ed (if a ground source) right to the antenna. Of course, not all of it is off- frequency... depending on the RADAR or Comm system. A number of Colorado Amateurs DF'ed the EPLRS noise at Buckley AFB right up to the antenna (with appropriate permission to be on-base at the time) and later some careful negotiation with the system manager included pointing out that if he didn't notch out the Amateur repeater inputs (which the system CAN do, since it's so frequency agile), he was basically giving away the dates/times of active training missions to anyone with an Amateur UHF HT talking on a repeater in the area, along with just general begging... I hear that this is very location dependent, and probably also had to do quite a bit with the fact that one of the Amateurs talking to them was a RADAR/SIGINT expert from a past life... I think. He won't say. Hah... those of you who've done those jobs get it when I joke about that. Anyway, haven't had any EPLRS noise now for many years here in the Denver area... I'm sure one can spin the dial and still hear it in other sections of the band during missions, but not on the repeater inputs... system manager here was SMART and got it.

There are technologies like TDM over IP that have much less jitter and dropout issues.. but it still is reliant on the IP link being stable and not overloaded as well as not interfered with. VOIP is essential not going to be very real time and as a udp protocol is not very error correcting...The delays and dropouts may or may not be worth your effort... http://allstarlink.org/ these folks have a network application which could serve your needs.. but inherent system delays may still be more than you are willing to use on a repeater.. There generally is no provision for voting multiple receivers in any technology based on IP besides TDM over IP.. and that requires good link bandwidth controls..

As an inter-site link, I was thinking of using some sort of VOIP arrangement via the internet. I'm curious if anyone has tried something like this: My idea is to use a point-to-point, private link (i.e. not IRLP or Echo) to pump audio and maybe even some signaling between sites. The receive site would consist of the receive radio, controller (most likely an Arcom), and a PC to do the encoding/streaming. The transmit site would consist of a PC to decode the audio stream, a PL decoder for TX logic, and the TX radio. The basic premise would be to take audio from the RX (PL filtered), fed thru the controller, mixed with link PL, and fed to the PC's audio input. The PC then streams the audio over the internet to the RX site PC, where it is decoded and fed to the TX radio, which will be keyed by a PL decoder (provided the IP encode/decode process hasn't mangled the PL). Whew... Now, question is: will it work? Or more properly, has anyone made this work? I'm going to try it on a small scale just to prove concept, but I'm curious if anyone has tried this already. My intention is to use something along the lines of Winamp with Shoutcast or Windows Media Encoder to stream the audio. I'd rather find a Linux-based CLI encoder if such an animal exists. I had thought about using IRLP nodes as endpoints, but IRLP policy would preclude that. Thoughts? Encouragement?
