TX LO (altvoltage1) is now powered down on RX and enabled on PTT, instead of staying on continuously. Removes the TX carrier leakage that showed up at the VFO frequency in the RX spectrum (and persisted after MOX), and stops idle TX-LO radiation. ApplyTxLO sets powerdown from FTransmitting, which also recovers the LO if external software (e.g. SDR Console) left it powered down. RX LO (altvoltage0) is kept on — receive is continuous; QO-100 full-duplex still works (RX LO separate). Trade-off: re-enabling the TX LO re-runs the AD9361 synth calibration (a few ms), so the first syllable on SSB may be slightly clipped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
