Tentative goals include 15-second T/R sequences, sensitivity around S/N = вЂ“20 dB, occupied bandwidth less than that of JT65, and capability to decode as many as 10 or 20 signals in a 2-kHz bandwidth.вЂќД«ut, Taylor added, developing new modes takes a lot of time, and results are not guaranteed. вЂњWe are experimenting with several such possibilities. вЂњWe are very much aware that a mode with most of the excellent characteristics of JT65, but with faster turnaround time, would be a big winner in such situations,вЂќ Taylor commented on behalf of the WSJT-XВ development team. WSJT-X developer Joe Taylor, K1JT, weighed in to express his appreciation to all who shared their ideas and experiences using JT9 and JT65 modes during recent multi-hop E-skip openings on 6 meters. Yet, being a propagation buff, I love the idea that I can leave the rig on 50.276 in JT65 mode and then see who I hear throughout the day via PSK Reporter.вЂќ вЂњI often find that often one cannot complete a QSO due to QSB and the ins and outs of Es. вЂњA few days ago we had a great opening on 6 meters, especially here in the New England USA area, given our latitude,вЂќ he noted. Joe Dzekevich, K1YOW, of Harvard, Massachusetts, sounded a similar theme.

Iain MacDonnell, N6ML, was among those remarking that, while the use of JT65 for working E-skip on 6 meters has really taken off, itвЂ™s too slow to be practical for openings that only last a couple of minutes or so. MSK144 and the fast JT9 submodes allow much shorter transmissions, but they do not offer the multi-decode capability that JT65 users find so effective.

A recent WSJT-X reflectorВ discussion allowed that, while the slow вЂ™JT modes like JT65 and JT9 have excellent sensitivity, their 1-minute long transmissions may not permit completion of a contact when evanescent signals pop up and quickly disappear under certain E-skip conditions.

Recent sporadic-E propagation openings on 6 meters and elsewhere have pointed up the need for a digital mode having faster turnaround time than currently available software versions offer.
