Recent tests suggest Q65 has several advantages over JT65 for EME, with better performance on very weak signals and potentially replacing JT65 for moonbounce work. Q65 offers variable T/R sequence lengths and tone spacings specifically optimized for EME and other weak signal applications. The new MAP65/QMAP software provides automatic polarization-matched reception across 90 kHz sub-bands for both modes. Looking for input from operators who've made side-by-side comparisons. Are we seeing the migration from JT65B to Q65 that was predicted? Reports indicate Q65 can decode down to -28dB S/N ratio.

We've definitely seen Q65 activity increasing significantly on 2m EME, especially weekends. The signal averaging feature in Q65 is remarkable - it tracks received sequences and pieces information together over multiple transmissions for successful decodes. Measured about 2-3dB improvement over JT65B in marginal conditions at our contest station.

QMAP integration with WSJT-X provides automatic Doppler compensation which is particularly valuable on 1296 MHz and higher bands. The selectable T/R sequences (15,30,60,120,300 sec) and submodes allow optimization for specific path conditions. Still seeing plenty of JT65B activity though - not everyone has migrated yet.

Q65 decode tags like "q1", "q2" etc. show the AP decoding process and number of averaged sequences - really helps understand what's happening during difficult contacts. Running basic EME setup here, consistently seeing around -22dB signal levels with Q65-60B mode. The extra sensitivity definitely helps on marginal paths.
