All Stat is dependent on Asterisk's app_rpt. Only IP link with analog audio I have going currently is through two Simoco SDB680 repeaters. Native interconnection, will integrate with any SIP so it could theoretically be used for app_rpt linking. Sent from my iPhone using Tapatalk

Remember the Audio PA is floating so DO NOT ground either of the speaker leads. Doing so will destroy the audio amp. They are made to float with an 8 ohm load. Sent from my iPhone using Tapatalk

Ironically, this post gave me an interesting (dangerous) idea. Simplex repeater, P25 receive, analog transmit. Subs are programmed to receive analog and transmit P25. Sent from my SM-T350 using Tapatalk

This. I've been forced to install some low tier repeater setups using LMR400. I've always noted that it should've been a different type of coax so when it does have to be replaced in a few years it'll be documented that a senior systems tech stated that.

They may have an office in Austin. Who knows. Sent from my SM-T350 using Tapatalk

It can be set in the front panel. Don't remember if they do MPL though. Sent from my iPhone using Tapatalk

We live in an era of Nationwide systems. Look at Bearcom's licensing across the country for example. The don't link them all but provide the ability to rent time regionally. Sent from my iPhone using Tapatalk

Got it on the service monitor and squelch shuts at -119 dBm…which worries me. Probably going to break out the breakout box and play with it some or grab another. Sent from my iPhone using Tapatalk

Info you seek is in the service manual. Sent from my iPhone using Tapatalk

I'll take a look and see if I can't figure out where it is. It could only be at one of a few sites to have any form of wide area coverage. Bee Cave, Trail of the Madrones, and a few more. I know it's not at Bee Cave. I know it's not on the Austonian (Bearcom is the only thing up there). Could be in one of the clusters at Trail of the Madrones. Sent from my iPhone using Tapatalk

I've heard the Maxtrac/Radius heads will not work but I'm not going to question it. I managed to pull a VHF expanded logic GM300 from the junk bin for testing and reading was a success. Here are some of my discoveries. Jumper required to enable repeater for headless operation. The R1225 is built on the same chassis as the GM300 so the GM300 head doesn't just enable programming, it actually mounts (though covers up the RX connector) which gives me an eventual direction I may move this setup.

Alright, so I managed to rescue 6 R1225s from going into the dumpster today. I decided at least one of them would go into GMRS service. So this will likely be a start to finish. These were all M04 (1-10W UHF) repeaters and were used in an analog trunking system for city services. For those wondering, they were removed in working order due to a wide area P25 upgrade (to VHF). Also they were all utilizing 100W external PA's (reasoning for be LPI repeaters). As you can see, these are headless. So first step (which I'm still working on) is to read the radio. Getting a control head on it will be the first step. To Be Continued… Sent from my iPhone using Tapatalk

Make sure hub is disabled. Which Rick? Sent from my iPhone using Tapatalk

Solder type does t really exist for mini-UHF. It really crimp only. Of if you really want to get energy efficient (the NHRC micro is a good choice) you can run the transmit radio via the ignition sense line. Using an additional timer if there is X minutes of inactivity you can pull power from ignition sense and turn it on and off. Sent from my iPhone using Tapatalk

You can do it with most GM300's. Look up the GR300/500 manual on the repeater builder site. Sent from my iPhone using Tapatalk

I'll also add, I've been seeing a lot of issues with mobile duplexers here lately (even Celwave/RFS). Anything much more than 35W and they start de-sening even though they are rated at 50W.

I'm just gonna point this out, Motorola PA's are notoriously narrow in their efficiency. A 40 watt rated PA on a Radius series mobile is 23% efficient from 40W to 25W, beyond that its efficiency dwindles. The 25W version is 24% efficient from 25-10 W (but has the same heat sink as the higher power model). In retrospective, the 20W GE custom MVP is 29% efficient from 8-20W. What do I mean by efficient? I mean that the output in RF is that percentage of the total power drawn in current. That means for your average 25% efficient radio you need 4 times the power output just to provide power. It also tells you how much heat is being generated from the circuit (conservation of energy). When it comes to solar powered repeaters, one is better off running 10W or less and focusing on antenna systems. Avoid the Chinese junk (even antennas) as you want something you only have to buy once. Quality feedline, (avoid LMR in a full duplex environment), and proper installation. General rule of thumb is your solar system needs to be able to carry your load in snow shedding. Sent from my iPhone using Tapatalk

For your "average" (Midwest semi-flat) terrain you'd see roughly 150% coverage increase at 90 versus 36 feet. 462 MHz is very line of sight oriented. Power is less important than location. Sent from my iPhone using Tapatalk

Technically that would be a page…which would fall under the beacon category. Sent from my iPhone using Tapatalk

Actually, if you look up Part 95J it actually states that grandfathered licenses (that are still active) are to be given priority on the dots. Also where the clause about radios presaging the creation of the service being able to operate on the service. Sent from my iPhone using Tapatalk

Scrub PL from signaling. Sent from my iPhone using Tapatalk

Easiest way is to utilize a repeater, link controller and link radio. The repeater you are linking to needs to be a different frequency than yours (causes some issues). Your link radio also needs to be using a yagi antenna. You should be able to do this at 1W in most cases but I wouldn't go higher than 5W. The link radio is programmed (or channeled) like any other repeater you wish to use through your HT or mobile. The link port goes to the link radio and the controller controls the onsite repeater. When the link is active, the remote repeater will key causing the COR circuit on the link radio to open and pass audio to the controller. The controller then keys the local repeater's transmitter and passes audio from the link radio. When the local repeater receives a COR signal, it keys both the repeater transmitter and the link radio (which in turn keys the remote repeater). This system can be built upon and built upon. In this case the remote repeater would be the hub and the local a spoke in the hub. Sent from my iPhone using Tapatalk
