## Hardware bring-up milestone |
|
|
|
|
|
|
|
The system is now ready for first real hardware TX tests with ADALM-Pluto (PlutoSDR). |
|
|
|
The system has moved beyond first hardware smoke tests: live RDS now decodes on PlutoSDR, with stabilized sample-rate handling, persistent DSP state across TX frames, and coherent pilot/stereo/RDS phase behaviour. |
|
|
|
|
|
|
|
### What changed since v0.6.0-pre |
|
|
|
- live RDS path stabilized enough to decode on hardware |
|
|
|
- generator now keeps DSP state persistent across frame boundaries |
|
|
|
- RDS carrier alignment tightened against the stereo/pilot phase model |
|
|
|
- Pluto profile tuned to the working sample-rate and level combination |
|
|
|
- multiple DSP/control fixes landed during real hardware bring-up |
|
|
|
|
|
|
|

|
### What's proven |
|
|
|
- 82 tests pass (DSP, spectral, operator truth, engine) |
|
|
|
- FM IQ magnitude verified: all samples |I²+Q²| = 1.000000 |
|
|
|
- Spectral verification: 19 kHz pilot, 38 kHz stereo, 57 kHz RDS confirmed |
|
|
|
- Continuous TX engine runs stable for >60s in tests |
|
|
|
- IQ resampling 228k→528k preserves signal magnitude |
|
|
|
|
|
|
|
### First smoke test procedure |
|
|
|
1. Connect PlutoSDR via USB |
|
|
|
2. `.\fmrtx.exe --list-devices` — verify device shows up |
|
|
|
3. `.\fmrtx.exe --tx --config docs/config.plutosdr.json` — start in idle mode |
|
|
|
4. `curl -X POST http://localhost:8088/tx/start` — begin transmitting |
|
|
|
5. Tune FM receiver to 100.0 MHz — should hear 1kHz/1.6kHz test tones |
|
|
|
6. `curl http://localhost:8088/runtime` — check telemetry |
|
|
|
7. `curl -X POST http://localhost:8088/tx/stop` — stop |
|
|
|
8. Ctrl+C to exit |
|
|
|
### What this release means |
|
|
|
- suitable for continued real hardware bring-up on PlutoSDR |
|
|
|
- not yet positioned as a final 1.0 release |
|
|
|
- recommended as the current pre-release baseline for further hardware validation |
|
|
|
|
|
|
|
### Safety defaults |
|
|
|
- TX is OFF by default — requires explicit start |
|
|
|
- outputDrive 0.3 in PlutoSDR config (conservative) |
|
|
|
- Limiter enabled with ceiling 1.0 |
|
|
|
- Pre-emphasis 50µs (European standard) |
|
|
|
- limiter remains enabled by default |
|
|
|
- pre-emphasis remains 50µs |
|
|
|
- hardware operation still requires proper RF measurement and lawful operation |
