Transmission or signal generation support for eligible devices (BladeRF and HackRF) is progressively introduced with the following roadmap:
- Phase 1: version 2.2.0: generation to file (File Sink) with AM modulator with simple sine modulation. Fixed sample rate of 48 kS/s (no effective interpolation)
- Phase 2: version 2.2.x: full baseband interpolation chain: in AM modulator and Up Channelizer.
- Phase 1: version 2.2.0: generation to file (File Sink) with AM modulator with simple sine modulation. Fixed sample rate of 48 kS/s (no effective interpolation)
- Phase 2: version 2.2.2: full baseband interpolation chain: in AM modulator and Up Channelizer.
- 2.3.0: SDRplay came into play ...
- Phase 3a: version 2.3.1: Improve AM modulator with audio file input
- Phase 3b: version 2.3.x: Improve AM modulator with audio input (Mic) support
- Phase 3: version 2.3.1: Improve AM modulator with audio file input and audio input (Mic) support
- Phase 4a: version 2.4.0: FM modulator
- Phase 4b: version 2.4.x: WFM modulator
- Phase 4c: version 2.4.x: SSB modulator
- phase 5: version 3.0.0: BladeRF and HackRF support including final interpolation stage.
- phase 5: version 3.0.0: BladeRF and HackRF support including final interpolation stage.
