sdr_j_fm is a graphical software defined radio receiver dedicated to broadcast FM. Its narrower focus allows it to concentrate on FM audio reception, stereo decoding and the controls needed for tuning and improving reception quality.
The application supports several popular SDR families directly. Device libraries are loaded as required, so a build can include interfaces for different receiver types without requiring every supported device to be connected or installed.
This is free and open source software.
Key Features
- Receives broadcast FM using software defined radio hardware.
- Supports stereo FM reception.
- Perfect Stereo Separation control compensates for small errors in reconstruction of the stereo subcarrier.
- Improved input filtering helps separate stations that are close together in frequency.
- Filter can be removed from the processing chain when the additional processing is not required.
- Supports SDRplay receivers.
- Provides tuner selection when using compatible SDRplay RSPduo hardware.
- Supports Airspy receivers.
- Supports LimeSDR devices.
- Works with HackRF hardware.
- Supports ADALM-Pluto receivers.
- Supports RTL-SDR-based receivers.
- Can use appropriately formatted WAV files as an input source.
- Attempts to reopen the receiver used during the previous session.
- Stores and restores station lists using XML.
- Less frequently used settings are moved to a separate configuration panel.
