Hi Bryce,

I don't know if this is what you had in mind but there was a mesh/radio repeater setup in the presentation talked about in this thread.

Hope it helps

Hi Augustine,

The current plan is to (at some point) place a Bullet M2 with an omni at one of our (SVARA) club repeater locations. I don't know when this will happen. However, I checked the distance and I don't think a link will be possible without a few nodes between us as the distance looks to be around 80 miles.

The longest link I know of was around 30 miles. That was with near perfect conditions.

I tried to attach a path profile shot but the up-loader is not working. (See google link below) I think that "ridge" on your end would be a good spot to put a node in the air for your area but we would need to put nodes on those high points to connect our meshnets. I think 12 nodes would give us the coverage we would need.

I would love to do this but I would need to drum up A LOT more interest in my area to get that kind of support. Currently my personal goal is to get a central node up in my area and to make a couple of push-up masts for "field use". My hope is that if I can get a node in the air that people can connect to it will create more interest.

Hi Mid-Michigan Meshers!,

I live in Superior Twp. in Washtenaw county and am considering setting up a mesh node here at my qth.

It would be great if one of the nodes in Mid-Michigan could point an antenna in my direction so that we could work on expanding the BBHN coverage here in Michigan.

More information is in my post on the SE Michigan BBHN forum: http://www.broadband-hamnet.org/hsmm-mesh-forums/view-postlist/forum-53-southeast-michigan/topic-1549-inquiry-about-possible-mesh-neting-in-washtenaw-county.html

If we could do this that would be AWESOME!

As a mental exercise (for now), I am looking at setting up a backbone of ~18 point to point links ranging in distance from 5 miles to 35 miles. These links are in remote areas and connect ridgelines/hilltops which make good repeater sites. These sites are typically >=1500 feet above the surrounding terrain. I am interested in determining which links can be served by "regular" FCC Part 15 rules and which need a Ham license. As I understand it, these routers are using digital modulation of a single channel, not "frequency hopping".

I would like to confirm with you all that the big thing I need to pay attention to for Part 15 compliance is 15.247 (c) (1) (i-ii), and 15.247 (b) (3). Specifically, in the 2.4 Ghz band, I need to reduce the maximum power (30dBm) by 1dBm for every 3dBi that the antenna exceeds 6dBi. In the 5GHz band, the maximum power is 30dBm regardless of antenna.

So in the 2.4Ghz band, it's the combination of power and antenna which trigger the need to use Part 97 rules.  In the 5Ghz band, the need to use Part 97 rules is determined solely by power.

Secondly, I would like to get a couple of identical radios and an assortment of antennas to probe the performance on various links. Do you have recommendations as to which radios work best, and/or which antennas perform well with them? 

Eventually, I will need to investigate performance for an omni antenna at each of the backbone nodes, connecting (probably) to a mobile/transportable high gain antenna. One thing at a time.

Thanks for your advice!!

1. It's Field Day.  Expect your network to stop for any one of a dozen reasons.

2. Why use a program that does this?  Having a corrupted electronic log is worse than using paper logs.

Hello All Volusia County Hams,

The Daytona Beach Amateur Radio Association will have their 2015 Field Day at the Volusia County Fairgrounds

3100 E New York Ave

DeLand, FL 32724

We will have several mesh nodes setup and will be demonstrating HamChat, IP video and VOIP.

Have a great Field Day

The post with the old URL got me too. The link in the menu to the left seems to work though.

Thinking about how I might use the mesh myself, then looking at how my organization uses technology for incident response, I have come to believe that support of land mobile radio (PTT radio) on the mesh is a key feature.

Personally, I want to wander around in the woods with a little 5W handheld and still have my signal get out. My organization relies heavily on land mobile radios (not part 90, since we're the Feds, but similar) in sparsely populated areas. Our CIO has made public statements to the effect that FirstNet is an interesting thing to keep an eye on, but since support of land mobile radio is not on the road map its not likely something we can use anytime soon.

My mesh related desires would be to try and establish a set of fixed mesh nodes, to which a mobile mesh node could connect. A set of some or all of these should support a low power transceiver with a Radio over IP controller. This segregates the architecture somewhat, into "IP network" and the more traditional "radio".

Beyond the simple ability to receive and transmit, the system needs some way to route and receive calls. Simple if you're sitting at a computer console, clicking on the transceiver you want to activate. Harder if you're just keying the mic on an HT in the woods. The solution will probably involve DTMF "dialing". Ideally, I would not have to know where a person is. If I could just say "go find xy7zwq" the system should route the call. However, this requires a way to uniquely identify each radio connected to the system. Quite a lot of utility could be had just by being able to specify default behavior and allowing manual dialing of RoIP enabled nodes.

I don't have much experience with VoIP/RoIP or mesh for that matter. What I've seen on this site is very telephone oriented (radio->phone patch->voip->mesh). Do you know of any effort to make an integrated RoIP gateway/software defined radio?

Thanks for all your work on this!

Has anyone here had a chance to try the new Icom WLAN radios yet? On the Mesh?

How do I setup asterisk to allow a call from a PBX extension to an ip address not connected to the pbx?

I see a link on the web page for a google map of existing mesh nodes which doesn't work.

Why bother creating a static map that somebody needs to keep current? it would be easier to either setup an aprs beacon announcing the presence of a mesh node similar to the way voice and digis ID, or to create an APRS-IS feed to dump the node info into the internet stream where it could be easily found. The web sites already exist to display the data and in the event of poor/no internet, the RF beacon would still work. Even if you dump the coordinates only onto the APRS-IS, a reverse IGate should spit them out on RF for field visibility.

Thoughts?
