Blue Line on Map

[Linus]

I was looking at the map of repeaters and I noticed a blue line on the map running from WI through line A and into NJ. It appears to link a few repeaters. What is the line? Does anyone else see it?

[PastorGary]

Since the west end of the blue line ends at WQTA313's location, perhaps Jake can tell us what's up with that... i'll send him a memo and hopefully his computer or tablet is operating at the moment.

The line you see is me testing a linking system with Rich WQEJ577, who runs this site, using asterisk to see how that kind of linking works in the GMRS world. Others who maybe interested should contact Rich too. Right now there are only 3 nodes.

Thanks, Jake - please disregard the backup email that I just sent to you regarding this thread.

[Linus]

Very cool. I like the idea.

The staff moved this thread from the MyGMRS related posting area to here at 'Technical Discussions' where it may get some additional attention and discussion.

Thanks.

I know of several linked systems on the amateur side. There is an internet linked system called WINS out here on the west coast. We also have something called the Evergreen Intertie. This system is amazing because the repeater linking is RF only and it has a network covering a large geographical area. The system looks like a gamma symbol overlaying a map of the west coast. It starts in Northern California up to Seattle. From Seattle it makes a right turn and extends to Western Montana. The repeaters can be connected using DTMF codes. This allows the user to tun on segments of the system when needed.

 

It would be nice to see the same sort of linking in GMRS.

I knew asterisk was used on the Amateur side of linking but never knew it was possible to do something like this in GMRS. So far everything works and sounds great. It sounds like the NJ repeaters are locally right there with me. I agree you Linus. Would be cool to see some more linkage in GMRS. Especially if you own multiple repeaters throughout a state, it would be very nice to be able to link them together to help keep in touch.

     From what I have heard I don't think GMRS repeaters are supposed to be linked.  I would love to se linking because in a natural disaster it would be nice to get long distances out of requests for equipment and medical supplies to an area far enough away that was unaffected from the storm or whatever.

     I re-read my earlier post and forgot to answer your "A line" question.  The "A line" is a map line showing the restriction of using the 462.650 and 462.700 because of a treaty with Canada.

 

     It is defined in 47CFR 95.45, which references 47CFR 1.923 and 1.924, explaining the use of the 462.650 and 462.700, and the repeater offsets of 467.650 and 467.700, North of the A line, and east of the C line in Alaska.  There are 18 states listed that are affected by the A and C lines.  I heard of it because I am also affected by it, and had to research it to pick a repeater frequency pair for Toledo, Ohio.

We've just added a new repeater to the network in Brick, NJ and it's undergoing testing. So when you see more blue lines, it means we're growing! Anyone else who may be interested can send me a PM and I will give the details.

Why wouldn't you be able to link? All the rules say is that interconnection to the switched public telephone system is prohibited (written before VOIP was ever implemented anywhere).

 

Asterisk is the basis for both Allstar and IRLP. VOIP linking may not be the best solution for natural disasters as internet can be assumed to have the same or less reliability as a phone line. A better option for disaster based setups would be an rf based link system with a VOIP node on the hubs.

the rule as I understand it means no phone patch in a nutshell.
