Compatibility Information
A compatible computer, SDR software and suitable antenna are generally required. Software availability and setup vary by operating system. Check the official product documentation for supported frequency ranges, drivers, software and bias-tee operating instructions.
Setup Guidelines
- Connect the receiver to a compatible USB port.
- Install suitable drivers and SDR software following the software provider's instructions.
- Connect an appropriate antenna using the compatible SMA connection.
- Select the correct device and tune to frequencies you are permitted to receive.
- Enable bias tee only when required by a compatible accessory and after checking its voltage and current requirements.
Important Safety and Use Notice
Do not enable the bias tee with incompatible equipment, as DC power on the RF connector may damage connected devices. Follow local radio-monitoring laws and respect privacy. This receiver is not a transmitter and does not authorise access to encrypted, private or restricted communications.
