Clearly, the 7070 watering hole is used 24/7 by narrow PSK31 stations as long as the band is open. The contester can unfortunately use SSB voice in that part of the band. He may not have known or cared that this is about the hottest digital area on 40 meters, but of course the PSK31 stations were there first.
He may have been on earlier and the propagation could have changed. But probably not as he seemed to come out of nowhere and then got no response and gave up after a while. The other stations were higher in frequency and I could not be sure of the language. It sounded like French but perhaps a Caribbean patois? Because of the type of smearing modulation from SSB, I have come to the conclusion that bandwidth is not a good way to segregate signals. The mode really does need to be taken into consideration. 73, Rick, KV9U Jose A.
