To set dual tuner mode in SDRuno

To set dual tuner mode in SDRuno, you need to be using an SDR device that supports multiple tuners (e.g., the RSPduo from SDRplay). If you have an RSPduo, here’s how to enable dual tuner mode in SDRuno:

🔧 Steps to Enable Dual Tuner Mode in SDRuno (RSPduo only)

1. Connect your RSPduo to your computer.
2. Launch SDRuno.
3. In the Main Panel (Main Window):
   • Click the “OPT” button to open the Settings window.
4. In the Settings window, go to the “Device” tab.
5. Under “RSPduo Mode”, select:
   • Dual Tuner (This enables the use of both tuners independently)
6. Close and restart SDRuno for the change to take effect.

📻 How to Use Each Tuner:

After restarting:

• Launch two independent SDRuno receiver instances:
  • Click the + (plus sign) in the Main Panel to open another receiver.
  • In each instance, go to Main Panel > SETT > Input and select Tuner 1 or Tuner 2 accordingly.

⚠️ Notes:

• Antenna Inputs: Tuner 1 and Tuner 2 use separate antenna inputs. Make sure you’re using the correct ports.
• Bandwidth: In dual tuner mode, each tuner typically supports up to 2 MHz bandwidth.
• Processing Load: Dual mode uses more CPU. Make sure your system can handle two simultaneous streams.
