I just use Zello (It's not LAN, but it is private). Install VB Audio Cable, set SDRTrunk to play out to the virtual cable, have Zello capture the virtual cable audio and broadcast it out. There is an audio delay of maybe 1 second or so from what is being played on the computer. When you are connected on Zello through your iPhone, it records the audio also so if you didn't understand something you can go back and re-play it easily.
Here are some instructions I typed up:
- Create two Zello accounts using two different email addresses.
- Install Zello on your desktop that has SDRTrunk. Log in and go to settings.
- Go to the "Audio" and set the recording device to your VB Audio cable.
- Go to the "VOX" tab and enable VOX.
On this part, you need to play with the settings to get it just right. If it isn't perfect then it won't capture anything at all. Here are my settings for example:
Code:
Activation threshold: -75 dB
De-activation threshold: -75 dB
Trigger time: 100
Relaxation time: 800
If you are having problems, make sure to check simple things like if SDRTrunk is set to play back to the correct audio cable.
- Open Zello and create a private channel, name it whatever you want. Make sure it is highlighted so it is broadcasting to there.
- On the bottom of Zello, there is a little Microphone icon and a Lock icon, click the lock icon so that it is red.
The red lock icon means it is capturing anything coming in on your VB audio cable (as long as it's being picked up by the settings from the VOX tab), and broadcasting it to your private channel.
Now on to the iPhone:
- Go to the App Store and install Zello.
- Open it and log in with your other account.
- On your desktop, invite your second account to your private channel.
- On your iPhone, accept the invite and join the channel.
- You have to make sure the "Power" icon at the top is green so that it is connected.
