Connecting The Audio – No K3/0

Connecting to the K7RL Station without a K3/0

If you are connecting with a K3/0, skip this section and go to “Connecting with a K3/0.”

For best results, I recommend a wired internet connection, unless you have a very strong WiFi signal.

If you’re not using a K3/0 to connect, you’ll need to download a small audio program for access to the radio audio. Click the link below to download and install this program.

Please note this is a Windows based program. Apple not supported at this time.

After installing the software, you will see a Client version and Server version on your computer. You will only use the Client version.

Once the Client version is running, you’ll need to make some quick changes to connect. Click the gear over on the right hand side to access settings:

Remote Connections

You should now see settings menu. The General tab is left alone, no changes required.

Click the Remote Connections tab.

RemoteConnections

Now click “New Host” and you’ll get this window:

RemAudNewHost

  • Host Name is your call sign
  • URL or IP Address is: k7rl.hopto.org
  • Audio Port is: 4000
  • User Name (call sign) is your call
  • Password supplied via email once your time slot is confirmed
  • Click “OK”

Audio Devices

Click “Audio Devices.” You should see the sound card you’ll be using for audio. These are default settings based on your Windows configuration. If you make any changes here, click “OK” to record those changes.

Audio Codecs

Click “Audio Codecs.” You can copy the settings here. I found these to be a good compromise between audio quality and bandwidth. If you make any changes, click “OK” to record those changes.

Audio Buffers

I advise using the default settings, however, if you experience audio issues, any settings can be easily changed based on the author’s recommendations in this tab. If you make any changes, click “OK” to record those changes.

AudioBuffers

Set-up is now complete!

Starting Your Audio Connection

Press the play button in the Remote Audio Client window and you should hear the radio. You’ll also notice a red microphone to the immediate right of the play button. This is a mute/unmute feature for SSB audio. If you plan to operate SSB, the microphone must be clicked and it will turn red. As you see it here, it is in the mute position.

Play_Button

In the very bottom right hand corner of this screen you’ll notice a number (“0” in this case). When connected, this is your latency indicator. The lower the number the better. If is stays green, your latency is low. If that number climbs, it will turn red indicating the amount of latency.

Troubleshooting tip: If latency becomes a problem during operation, please make sure you have closed any non-essential programs/apps as excessive CPU usage can cause delays.

If you still experience delays, try stopping the audio feed on the Remote Audio Client, which is running on your local computer. Then press the play button to restart the audio feed. You can also try stopping and restarting both the server and client audio feeds.

If the steps above still haven’t resolved the issue, go back to Audio Buffers in settings and make the appropriate changes on the Remote Audio Client.

Next up, controlling the station
