Echolink installation procedure for the ZS6STN Echolink repeater

This Article describes the Echolink installation procedure for the ZS6STN Echolink repeater courtesy of Henry Stephan, ZS6MC.

Hardware in Use

  • PC/Laptop/Server with a Windows Operating System such as Windows XP Service Pack 3 or Windows 7 or Windows 8 or Windows Server 2008 R2. For the ZS6STN EchoLink Station I am using a Server using Windows Server 2008 R2.
  • 250GB of Hard Drive (can be less)
  • 10GB of RAM (2GB minimum)
  • USB Audio Device
  • USB Dongle with Sim Card or WiFi Hotspot with a Sim Card or ADSL Modem Connection
  • VDU (Video Display)
  • USB Mouse
  • USB Keyboard
  • Headset to plug into your PC or a USB Headset


STEP 1: Download the EchoLink Program from

  • Download the EchoLink Program onto your PC
  • Google EchoLink Set-Up and follow the instructions as per the EchoLink Website.
  • If you have not activated EchoLink before then you will need to “Register” on EchoLink before you can use EchoLlink.  This process is quick but may take up to 24 hours, just follow the EchoLink Instructions.
  • To check that EchoLink is working properly, once you are registered, Goto “Tools” select “Firewall Test”
  • If TCP 5200 Succeeded, UDP 5198 Succeeded and UDP 5199 Succeeded, then you can use EchoLink immediately and you do not need to proceed any further.


However, if after a number of attempts the Firewall Test still “Fails” then follow the Steps below. It may also be that your Anti-Virus software could be blocking EchoLink.

STEP 2: To Set-Up your WiFi Hotspot or Data Dongle

  • Connect a WiFi Hotspot or Dongle or LAN to the Server and allow the Software (SW) to download onto the Server
  • You will see the Short Cut loaded on your Desktop window
  • Now open Internet Explorer or Google Chrome
  • In the URL window, type in the URL of the Hotspot, for example, and press “enter”. Refer to the Hotspot’s Manual for this URL
  • Login and enter the Username (normally “admin”) and a Password (normally “admin”) and this will also be listed in the Hotspot’s Manual.
  • Goto “Settings”
  • Goto “Security
  • Goto “Virtual Server”
  • Enter into the Virtual Server Table the information/settings as shown. YOU MUST DECIDE AT THIS POINT WHAT LAN IP ADDRESS YOU WANT TO USE. I decided on using





STEP 3: Check the IP Address of your PC


  • Open the CMD prompt on your computer
  • Type in ipconfig and press enter
  • Your IP address of your computer will be listed. NOTE DOWN THIS IP ADDRESS. This address may be different to the one I listed above. If they do not match proceed to the next step.


STEP 4: To Open the Ports UDP 5198, UDP 5199 and TCP 5200 for EchoLink to work properly on your computer.

It is Important to note: For EchoLink to communicate with your computer the ports UDP 5198 and UDP 5199 must be configured to allow information through your Firewall or else the Firewall will always block these ports. So how do we do this?

  • Download the Port Forward program from:
  • Once the port forward shortcut is created on your PC open it and select “Trial”
  • Cancel “Purchase Now”
  • Select “Static IP Address”
  • Make sure this IP Address matches the IP Address of your PC and also matches the IP Address in your Virtual Server List, otherwise change it in the Static IP Address window
  • These three (3) IP Addresses must match one another.
  • Press the block labelled “ Make It Static”


STEP 5: To Check that your ports are OPEN

  • In the Port Forward program window select “Port Checker”
  • Enter the port number to check say 5200 and select “TCP”
  • Press “Check Me”
  • Wait 2 minutes and if all is okay the port check result will be “Your Port is Open”
  • Enter the port number to check say 5198 and select “UDP”
  • Press “Check Me”
  • Wait 2 minutes and if all is okay the port check result will be “Your Port is Open”
  • Enter the port number to check say 5199 and select “UDP”
  • Press “Check Me”
  • Wait 2 minutes and if all is okay the port check result will be “Your Port is Open”



STEP 6: If the Port Forward Check does not work then:

  • Contact your Network Provider in my case Cell-C on 084 1 555 555. (I have a Cell-C Sim Card in my Hot Spot)
  • Inform your Network Provider to activate an “Unrestricted APN” on your Sim Card. This involved filling out a form signing it, attaching a copy of my ID and sending it back to them.
  • The reason for this is that your Network Provider provides a Firewall service which is normally the first line of defence in preventing any dangerous viruses or programs from infecting your machine. In signing this form they relegate any form of responsibility and therefore you must make sure that your Firewalls and Anti-Virus programs are in place and operational.
  • In the meantime go back to Step 1 select Profile Management, create a “New Profile” for your Hotspot, call it “Cell-C EchoLink” as an example and where it states APN enter the word “unrestricted”. Normally the word “internet” will be in this block.
  • Save this profile and it will become your Default.

Once your Network Provider has done their job, and this can take up to 48 hours, your APN will be unrestricted and Port Forwarding will be OPEN.

You can test this as per Step 4 above.

To use your station as a –L (link) or –R (repeater) you will need a sound card between your Computer and your Radio. Most older soundcards use an RS232 port, however the radios of today use a data port normally a smaller USB port for control, or you can control the radio via the microphone input and speaker output.
