When testing materials at 2.4GHz, the microwave oven in your kitchen is your best friend. These units make 700 to 1100 watts of RF output at 2450MHz. This is the same frequency as your 2.4GHz mesh node.

To test PVC or any plastic under consideration, fill a glass or cup with water and put a sample of the plastic to be tested in the microwave. They should be in different places on the same turntable. Start the oven for 10 seconds. Examine the plastic to see if ANY warmth is felt on it. If still cold, restart the oven for one minute. Again check for heating.

Finally, replace your water in the cup with cold water and cook them both for 2 minutes.  If the plastic comes out cold, no energy is being absorbed. This means the plastic is transparent at that frequency. Be sure you know whether you will use any adhesive or joint compound in your project. If so, you need to create a joint, similar to what you will use, and test that combination also. 

You can use a microwave to test a number of materials in this manner but be sure not to put any metal in there. This test is also a predictor (but not totally accurate for 3.4 and 5GHz)

I am looking for a Tunnel Server to test my client.  Thanks.

I setted two nodes, many hams near me are working on it. please see the map and try to connect with us.

I sent and will keep sending email to other hams around us. I found email address in qrz.con guided for the grid option.

I'm working to add two amps [ 4w ], and an antenna onmi, and a yagi; all powered with a solar panel using a POE . The second node is to work VoIP, etc. at shack.

Hello All,                                                                                                    

I have just unbricked a WRT54G Ver. 2 router using a jtag cable, the HairyDairyMaid utility and reflashing the entire flash with an entire flash backup from another working hsmm node, also a Ver 2. box. After 3 hours, the flash completed without incident. The good news is that the newly flashed router now boots and is an identical clone of the other node. The bad news is that it is an identical clone all the way down to the various ip addresses, and thus the mac address in the node.

I've tried changing the ip address in the CFE module and reloading it to flash. Unfortunately, this did not work.... Of course, I changed the node name through the web interface but that did not work since the ip addresses were still duplicated.

What is the best way to proceed and get a unique node on the air? I assume that I'll spend another 3 hours to reflash the whole image to get a working node and go from there...

Ah! Thanks for correcting me. 

So to answer the OP:

Install hamchat on kp4rv-3

On one computer, connected to any node, go to the stated address with your browser.  Enter a callsign. 

On the second computer, connected to any node, also go to the same link and enter a callsign. 

Type a message on either computer and hit "enter" and it appears on both computers.  Repeat. 

Does PVC attenuate 2.4Ghz signals? Looking for a way to package some antennas.

I have two Linksys WRT54GS V2's.   These are the one's with extra memory to support my tunnel add-on.

SOLD!  thanks.

I am looking for someone with a mesh in Oregon who has a tunnel who I can test my server/client on

thanks

Just install hamchat on one of your nodes.  You probably want to add a link to it as an advertised service that would look something like:

http://YourNodeHame/cgi-bin/hamchat.pl:8080/

The "client" is just your browser. 

Dunno if you need to upgrade, I've used 3.1 from the start. 

Hi Guys!

How I can add on on my mesh to be able to have keyboard to keyboard communication? Do I need the upgrade of 3.1 to do this? Do I need another computer acting as a server? Do not know to much and need help on this please.

Hi All, I am attempting to pioneer a mesh for my rural area. As part of this task, I am looking at installing sector antennas and mesh nodes on the club-owned repeater tower and maybe a couple commercial towers. I will also likely have a set of sector antennas on a small tower on my hilltop.

What are some of the things/problems that I will have to consider with putting, say 3 x 120* sector antennas on the same tower? Do they play well as long as they are pointed in opposite directions or do they need extra shielding? I figure I'll run shielded cat 5/6 cable down the tower to a Ubiquiti ToughSwitch. I may also link the towers (if I can) with a 5.8 GHz link, but that's a discussion for another day.

Any tips or pointers for installing multiple nodes on one tower?

Thanks in advanced for the help and advice.

I am unable to upload an avatar to my profile.  Any help appreciated.

I ran into the same error. I ended up connecting the node to the internet and installing the package through the admin tab. The asterisk package installed fine after that.
