The ERDN Test network is desiged to be a test platform to play with various digital modes available to Amateur Radio operators. It is sponsored by Steve Miller, KC1AWV.

Testing may include but is not limited to: (and is actively being expanded upon)


Why not?

Also, I needed an experimentation place outside of production, and off of mainstream RF. I am sharing this network for other Amateurs as a place to test and experiment as well.

Basically, if it can work here, it should work in 'the real world'.

Don't have the resources available for DVSwitch yet and want to play with what DVSwitch can do? Are you looking for an easy place to do a demonstration of how an analog radio can talk to a DMR radio? Or how about YSF to DStar? Can you think of something else you want to test before going into full operation? This and many more things can be done on the ERDN Test Net.


Look at the diagram above. Squared rectangles are "endpoints" that can be used to connect to the network. Rounded rectangles are the intermediate software transports being used. The comments on the connectors are describing what type of transport is being used.


Connect your node to ASL 48776. Transmissions made on your node should be heard on 48776, and on the other endpoints. You can check to see if your endoint is connected by going to the Allmon2 page for Node 48776.


You have a few endpoint options, but here I will describe how to set up for a direct HB Protocol connection to the test network.

Directions for manually adding a Master Server come from IS0BZC's page. I'm basically translating it from Italian to English. Badly.

  1. Log into PiStar through your browser. Default login is pi-star/raspberry
  2. Once logged in, near the top of the page choose the Configuration menu, then select Expert.
  3. Select the SSH Access option.
  4. At the SSH screen, log in using the same username and password used for the web access.
  5. Once logged in to the SSH session, gain superuser access by using the command sudo su
  6. Change the SD card from Read-Only to Read-Write by issuing the command rpi-rw
  7. Change the current working directory to the root user's home folder with the command cd /root
  8. Use the command ls to list the contents of the current directory. You should see a file there named DMR_Hosts.txt
  9. You will need to edit the DMR_Hosts.txt file to add the ERDN Test Network master server. Use the command nano DMR_Hosts.txt to edit it. It's important to read the whole file, including the comments. Did you read it? Good, read it again.
  10. At the bottom of the file, add a line with the ERDN Test Network master host information. The line should look something like this:
  11. Save the file by pressing CTRL + O and pressing Enter to save the file with the same filename.
  12. Exit the nano editor by pressing CTRL + X
  13. Go back to the Admin menu, then select Power, and click on the big, green Reboot button.
  14. When Pi-Star has finished rebooting, log back into its web interface.
  15. Choose the Admin menu, then select Update. This will import new information from the PiStar repositories, as well as the changes you made earlier in the DMR_Hosts.txt file.
  16. When the update finishes, reboot the Pi-Star again. Go to the Admin menu, choose the Power option, then click the big, green Reboot button.
  17. Now, when the Pi-Star has finished rebooting, log back into its web interface and then choose the Configuration menu.
  18. Under the DMR Configuration menu, drop-down the DMR Master list.
  19. In the list, select the master name you used prevously in the DMR_Hosts.txt file. In my example, it was called ERDN_Test. It's probably at the bottom of the list.
  20. Click on the Apply button at the bottom of the DMR Master section. Pi-Star will then log into the ERDN Test Network master server.
  21. Once Pi-Star has logged into the master, use TG 2 to talk on the local cluster. You can check to see if your hotspot connected sucessfully by checking the ERDN HBlink Monitoring Server.


I haven't been able to figure out how to manually add a server into the Openspot's Homebrew server list just yet. If anyone knows how, please let me know and I'll add that here.


Add test.erdn.net port 9001 to your Radio list as a Network connection. You can name the ratflector 'ERDN' in the list.
