Sometimes in FT-8 mode I receive calls like this one:
It happens 2-3 times a week.
The problems are: 1) I never could look up such call signs 2) I tried to reply, but never got answer 3) I don't know what /R means.
Are these real calls or maybe just a noise that WSJT-X somehow managed to decode? So far I didn't log such events as QSO's. Maybe I should?
UPD: As Marcus pointed out, the checksum collision in FT-8 is very unlikely. Also I managed to figure out that "/R" means a repeater https://en.wikipedia.org/wiki/Amateur_radio_call_signs I believe it means that the signal was sent automatically by the device, not that the operators works through the repeater. Still I wonder - should I add repeaters to the logbook?
