The speaker's I2S channel was only disabled when idle, which leaves MCLK running. Its fractional divider (160 MHz / 39 1/16 = 4.096 MHz) makes a comb of lines every 256 kHz: one at 869.632 MHz, in the EU narrow mesh channel, lifted the LoRa noise floor from ~-102 to ~-85 dBm, and others land near GPS L1 and BeiDou B1. The channel is now deleted and its pins held low after each sound, and made again for the next one. Measured: noise floor -102 dBm, outdoor first fix 87 s (was 620 s and more). Also: TCXO at 3.0 V (the L2's part, as Meshtastic has it); GLONASS enabled on the L76K after each power-up; begin() on a running receiver no longer resets it (a reset threw away the acquisition in progress).
