Release Notes — v0.7.0-pre

Hardware bring-up milestone

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

Build for PlutoSDR

go build -tags soapy ./cmd/fmrtx
.\fmrtx.exe --list-devices
.\fmrtx.exe --tx --config docs/config.plutosdr.json

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
limiter remains enabled by default
pre-emphasis remains 50µs
hardware operation still requires proper RF measurement and lawful operation
