VibeServer 4.1.49 — the gain lock is per band

The lock is per band now. 4.1.47 shipped it as one switch for the whole receiver, which could not say the thing owners actually want: hold FM at a fixed gain while HF stays adjustable under a ceiling. Each band answers for itself, and the list says which — a locked band reads RF 7 · IF 25 🔒, an unlocked one up to RF 7 · IF 20. Lock All bands and the whole radio is fixed; that was always just another band.

A per-band ceiling set from the phone was ten times too tight. The setup page stores fm:250; the app stores what it shows you, fm:25.0dB, and the parser stopped at the 5 — so a 25 dB ceiling was really 2.5 dB. It looked like it worked, because a number went in and a ceiling came out. Fixed in the parser, so a hand-edited vibeserver.conf reads the same way. A bare number keeps its exact meaning: existing configs are untouched.

Android gets the per-band lock and, on a HackRF, the LNA/VGA split a fixed band needs — a total is enough to limit with and not enough to set with. Choosing a capture width there now really does pin it, which is what that screen has always claimed.
