Android SDR Driver Input Plugin

Introduction

This input sample source plugin gets its I/Q samples from the Android SDR Driver or SDRplay Driver apps. These apps enable support for RTL SDR, HackRF and SDRPlay SDRs.

Interface

1: Start/Stop

Device start / stop button.

• Blue triangle icon: device is ready and can be started
• Green square icon: device is running and can be stopped
• Red square icon: an error has occurred with the connection to the device. The plugin will continually try to reconnect.

2: Center frequency

This is the center frequency in kHz of the device.

3: Stream sample rate

Network I/Q sample rate in kS/s.

4: Local oscillator correction

This is the correction to be applied to the device's local oscillator in ppm.

5: DC offset correction

Check this button to enable DC offset correction on the device.

6: IQ imbalance correction

Check this button to enable IQ imbalance correction on the device.

7: Bias tee

Check this button to enable a bias tee, if the device supports it.

8: Direct sampling mode

Use this button to activate RTL-SDR's direct sampling mode. This can be used to tune to HF frequencies.

9: Sample bit depth

Specifies number of bits per I/Q sample transmitted via TCP/IP. This should be 8 for RTL SDR, but can be 16 for SDRPlay.

10: Server TCP Port

TCP port of SDR Driver to connect to. Typically 1234.

11: Sample rate

Specify the device's sample rate in samples per second (S/s).

12: RF Bandwidth

Specifies the bandwidth in kHz of the analog filter in the device. Available bandwidths are dependent upon the device.

13: Gain

Specify gain in dB applied in various stages of the device. Available gains will depend upon the type of device.

12: AGC

Check to enable automatic gain control in the device. How AGC works is device dependent.
