Today I heard SO1WS in Western Sahara on 17-meters. I noticed a very raspy FT-8 signal, and after checking the time offset, it turned out to be So1WS — however upon further review it was apparent that they were running the the “Fox” mode as they were having multiple contacts each transmit cycle. So I changed over to the “Hound” mode and gave them a call. Sure enough after a few cycles they came back. I noticed that my station never sent 73, but when they sent RR73 the “Log Contact” box popped up. Sounds like a good contact.
Interesting. Time to read the manual.
