Mesh Applications

In Ventura County, we support several different types of applications on the digital mesh network:



We support a VOIP PBX on the network.  If you’d like an extension off the PBX, contact Paul, WD6EBY.   A Grandstream phone is recommended for best compatibility.  Model 1625 is currently recommended.   You can also use a softphone (software phone).   Linphone for MacOS, Linux and Windows works well.  It can be downloaded here.

VOIP voice chat

We run a Teamtalk server on the network.  It supports text, audio and video chatting, and also allows you to share files and your desktop.  It can be used at any time and we encourage you to hang out there, just as you would on your local FM repeater.  

The Teamtalk client software can be downloaded here.   We have a Wednesday night voice net at 8:00 p.m. on the Teamtalk server.   If you’d like to participate, contact W6BI for an personal account on the server.   (userid:password of guest3:guest3 can be used for getting started).  The server hostname is k6pvr-svr.local.mesh  (it’s all needed; enter it as shown).

Note – if the k6pvr-svr server is not available, there’s a mirror Teamtalk server instance on w6bi-qth-srv that will be activated as necessary.

On the main screen when first installed, the third icon from the left on the top is “Enable Voice Activation”, and it’s defaulted to Enabled.  Click on it to disable VOX.

Under Client / Preferences set:

Your Nickname.  We use <name> <callsign>.

Your Push To Talk key.   Left Alt works well.

Under Client / Connection

Check the first two boxes:  “Connect to latest host on startup” and “Reconnect on connection dropped”.

Under Client / Sound System – make sure it’s configured for your preferred voice input/output devices.  A USB headset with microphone boom provides excellent audio.

Keyboard Communications

Ventura County uses a couple of different keyboard applications.

Internet Relay Chat

IRC (Internet Relay Chat) is one.  There are IRC servers linked together throughout Santa Barbara, Ventura and L.A. Counties (plus one in Arizona).   They are available for your use on the network.  Install an IRC client and join us!  HexChat works well for Windows.  Those servers are:

  • km6fq-rpi3
  • k6pvr-irc
  • n7qjk-host
  • k6tz-srv01
  • kg6wxc-host

Additionally there are web interfaces to the IRC network available.  They’re generally called “MeshIRC” and are available at least on the kg6wxc server.


Mattermost is a modern chat-server with advanced features.   Ventura County hosts two instances of Mattermost:

On the Internet here:

On the ham network here:

Both instances are linked together, and to the IRC server network.

Note: in order to join the Internet instance, you’ll need an invite from a Mattermost-using ham.

In addition to being web-based, there are Mattermost clients for Windows, Mac, Linux, IOS and Android.  So you can stay in touch everywhere 🙂


The Teamtalk server supports video chat if your link to the server is of high quality.

Beyond that, we have various webcams on the network. Most require an RTSP viewer to view them (VLC, Mplayer or iSpy for Windows).

Periodic screenshots of the webcams are available.
