Spectrum dominates the server↔client connection, and all three things that govern its cost were working against a poor link. **It was polled, one round trip per frame.** The client asked for a frame every 50 ms on a dedicated connection and waited for the reply, so the frame rate was capped at 1/RTT — on a 200 ms link, five frames a second no matter what was configured. Add SubscribeSpectrum alongside the existing SubscribeMeter: the server pushes frames from a per-rig broadcast that rig_task fills only while somebody is subscribed. A server too old to know the command answers with an error and leaves the connection usable, so the client falls back to polling on the same connection without reconnecting. **Bins were JSON floats.** 1024 bins spelled out as decimal text is around 10 KB a frame, ~200 KB/s at full rate — while the very next hop, client to browser, already sends the same information as base64 i8 in about 1.4 KB. Bins now travel base64-encoded whole dBFS, the resolution the display draws at anyway. Decoding still accepts the old array form. **Nothing was tunable.** [sdr].spectrum_fft_size and [sdr].spectrum_interval_ms replace the compile-time FFT size and cadence; [[remotes]].spectrum_interval_ms lets the client ask for less. 512 bins at 5 frames/s is roughly 3.5 KB/s against roughly 200 KB/s before.
