The "rate-follow refused" red line goes away once a working rate is chosen. A refused sample rate put a red "DSP rate-follow refused ..." line on the device panel, and it stayed there even after you went back to a rate that works - so a receiver running perfectly looked as if it were still refusing. Now the next accepted rate clears it. Other messages on that line, such as a failed gain or bias-tee setting, are left as they are.
Since 0.99.29 every rate a radio's own menu offers is accepted, so the refusal itself only appears for a rate nothing can serve.
