With the ever-increasing popularity of the FT8 mode, there are times when I am decoding in excess of 36 stations on a single channel (JTAlert display slot maximum). And I am practically forced to transmit on a slot that straddles two adjacent stations, hoping that increases the chances of being decoded, without impairing the neighbor's decodes.Hi Bruce,
we have example .WAV files that decode as many as 60 signals. Of course propagation variations and geographical distribution will mean that many more stations can be actively engaged in QSOs on one SSB width channel World wide. Those with SDRs and other receivers with wider bandwidths can extend their operation to more than a typical 2400 Hz width, others less fortunate can always tune up of down a bit to capture signals of interest, even though they may not be able to decode all signals present at once.
One thing is certain, if everyone obeyed there licence conditions and used the minimum power necessary to complete QSOs there would be even higher occupancy.
