Earlier versions sometimes choked on rapid band changes or overlapping signals. 2.2.160’s decoding engine handles adjacent QSOs with surgical precision — fewer missed calls, less QRM blindness. jtdx 2.2.160
Protocol handling in JTDX includes tight timing synchronization to UTC, tone detection via FFT, candidate extraction, and forward error correction (where applicable) combined with call-sign and grid decoding. JTDX often implements alternative parameter sets and thresholds to trade false-decoding rates against missed decodes. : For general public use, JTDX SourceForge and
