Please note this is not for the faint at hart. It takes a lot of tweaking and setting up different software programs to relay the audio onto a Mesh Network. Inter-connectivity between the Mesh Node, Netgear Switch, Mesh AP, Raspberry Pi, Internet Modem/Router, Laptop, Cellphone and Software are taking place when this feature is activated. I had several requests to provide more details on how I achieved this. Please note “my way” is not the only way to achieve this however I wanted it to be done without connecting the Internet to the Mossel Bay Mesh Network. I am sure there are other ways and if you do it in another way, please send me the details to share with other mesh administrators. (Email: sawois05ATgmaiDOTcom)
You should know the workings of:
- Echolink – I suggest you learn more about it at: http://www.echolink.org/ The technology is fairly old but is still used very effectively worldwide.
- Sound-card Setup – Configuring Sound and Audio Devices. Google is you friend to search for you specific Sound-card settings.
- Amateur Radio Sound-card Interface Setup and usage – Google or you Interface Manual is your friend. Also read-up on connecting this device to your specific amateur radio transceiver if you also want to relay audio on a link or repeater.
- Setting up a Mesh Node, Mesh AP, Raspberry Pi, Various Servers, Home Based Internet Modem/Router and Mesh Network Switch. Google and Aredn is your friend.
- Audio Mixer Setup – Google or you Mixer Interface Manual is your friend.
- Voice over IP (VOIP) – Depending on which VOIP Client and Server you use, Google is you friend.
- Iphone or Android Phone – Connecting to the Mossel Bay Mesh Network and listen to live audio. Here are two links but more to follow soon. https://mosselbaymesh.co.za/wp-content/uploads/2017/12/How-to-listen-to-live-audio-music-on-the-Mossel-Bay-Mesh-Network-via-your-Android-phone.pdf and https://mosselbaymesh.co.za/wp-content/uploads/2017/12/How-to-listen-to-live-audio-music-on-the-Mossel-Bay-Mesh-Network-via-your-Iphone.pdf
This look like a time intensive and daunting task. I said that this is not for the faint harted but remember “No Pain No Gain” and if your hart is in it then you will persevere to reach the ultimate goal and success. Note: If I can do it with no IT Diploma or Certificate then you can do it as well. Ok for the purpose of this How To we will only be looking at streaming Echolink onto the Mossel Bay Mesh Network. Lets get started with the setup:
- Your home or laptop computer must be connected to an ADSL Modem Router. Ensure that you have a good Internet Wireless (WiFi) connection to your computer. I use a wireless connection and a laptop to connect to the Internet. The LAN connection on the computer is used to connect to the Mesh Network. You need to test your WiFi connection and LAN connection to ensure that both work independently from each other. In Chrome Browser I open the Mesh Node Access Page and in a new tab I access any Internet Web page. If both windows open you ready to proceed.
- You need to install the following programs on your home computer: VoiceMeeter Banana Mixer, Your VOIP Client and Echolink
- Now we need to configure these programs. I am only going to discuss the setup of the audio and sound settings of each of these. By now you should be familiar with the other functions and setups of each program.
VoiceMeeter Banana Setup:
Install the VoiceMeeter Banana Virtual Input drivers. Once installed it will show up under Virtual Inputs. (VoiceMeter VAIO and AUX) Open VoiceMeeter Banana. Click on – Hardware Input 1. Select KS: Conexant HD Audio Input (This is your computer sound card input device) Then select A1 and B2. Now set VoiceMeeter VAIO by clicking on the Equalizer circles. -12.0 Treble, 12.0 Middle Circle and -12.0 Bass. Select A1 and B2. Now onto VoiceMeeter AUX. Leave all circles default at 0.0. Select A1 and B2. Now set Hardware Out. Click on A1. Select: MME: Conexant HD Audio Output (This is your computer sound card output device) Now click on the VBAN Button. Go to Outgoing Streams. Click on which will turn green. Now enter your IP Number of you Mesh Node and Port Number of you VOIP Server/Client. If correct a green box will appear next to the IP Address Number. Finally click on VBAN is off to switch VBAN on. Block will light up in blue.
VOIP Client Setup:
Depending on the program you use this setup will differ. You might need a Server for your VOIP Client. I installed a server on the Raspberry Pi which is connected to a Switch. Ensure that your client and server communicate properly. Now go to and click on Configure/Preference/Settings. We are looking for the Audio Input and Audio Output settings. Audio Input: System: DirectSound Device: VoiceMeeter Aux VAIO Transmit: Voice Activity. Select Amplitude. Leave all other slides at default. Audio Output: System: DirectSound Device: VoiceMeeter VAIO Leave all other sliders at default. Select Advanced. Click Apply and OK
Click on Tools, Setup and then Audio. Select Input Device: VoiceMeeter VAIO and Output Device: VoiceMeeter AUX VAIO. Leave other setting default. Click OK. Now connect to station that is active on Echolink to see if all programs work in tandem. Once connected the Echolink RX slider will move up and down. Your VOIP Client will show TX. In VoiceMeeter the VInput: VoiceMeeter AUX slider will move up and down. In Master Section A1 and B2 slider will also move up and down as audio is recieved and transmitted.
If you now connect to the Mossel Bay Mesh Network via LAN or AP (Wifi) you can listen to Echolink on the mesh network with your VOIP Client. Just select the MsbMesh Echolink Channel and away you go! NOTE: This service will not work in the event that there is no Internet connectivity or audio from an Echolink Station/User/Repeater/Link.
