Funny no matter what Forum linking comes up in it always starts a POTS debate, one that's been beat to death. Nothing I do is over POTS, in fact the Asterisk server is sitting on optical fiber and the nodes on dedicated point to point connections or cable. As an IT professional of 25 years I can assure you DSL is not POTS. Unless you are doing an auto patch to a POTS line or using dial up for your internet chances are your internet has been been off the last mile for years.

#1. You cannot retransmit or relay signals from another service, except in case of an actual current emergency. #2. The emergency must pose immediate severe threat to life or property.. Very few weather warnings would meet the standard. And, for those, there are other, better, alert systems already in place.

Hi all, Maybe im stupid, Ive been told that before, but I don't see a problem. GMRS is a radio service for people that want a family or a friendly radio service. People that just want to pick up a mike and talk. Why does everyone want to make this into something it is not and never will be. If you need something more than what it is, get an amature license. I dont have an amature license and Im happy with it. Wow, you got me ranting. SORRY.

We are using Asterisk as the server (running on a raspberry pi 3) and the RTCM made by micro-node. Cheaper hardware solutions vs the RTCM are available but require other configuration. I have not used any of the other hardware so I wont touch on that. I chose the RTCM for its single unit design and application specific properties. The interfacing with the RTCM is rather simple, I went with the MTR2000 repeater for reliability, full duty cycle and used market availability. Our group hosts its own local node server (Asterisk running on a raspberry pi 3) with 6 repeaters connected to it. This local node also allows us access to the MyGMRS national linking network hosted by the owner of this site. By entering commands in Asterisk or using DTMF, links to other systems can be connected or disconnected on the fly. Things like usage counters and the visual map show links with red lines as well as what site is transmitting by changing its marker from green to red, all of this in real time. Its not as hard as it sounds, Rich from MyGMRS was a huge help, you can also find a linking thread in the private section here. Along the way I found a company that was able to build a custom cable for interfacing the MTR2000 with the RTCM, it provides a reliable solution that's repeatable and works flawless. The MTR2000 repeater can be configured to work with the RTCM rather simply using the repeaters wire-line card to handle the audio and the 96 pin J5 connector to pull ctcss, core, ptt and power. We are using the RTCM and MTR at 6 sites with a stand alone MTR at a 7th and could not be happier. These machines are worth every penny, its not 2 mobiles in a box its a true full duty cycle, commercial grade repeater. Due to the simplicity I have several more RTCM / MRT2000 combos ready to go I just need to fined a few more tower sites with internet. Hope this answers a few questions.

Nothing is ever easy when it comes to actually doing it. Maybe the concept would lend itself to a low powered solar application. I've talked 17 miles from a mountain top with only 4 watts.
