HI
Can anyone tell me in which part of the ft8 manual I find the explanation of how the protocol manages to send responses with related reports to multiple stations in f/h mode in the same slot (same bandwidth?)?
Thank you very much

thanks Wolfgang
but my interest is in understanding how
the protocol, in f/h mode, is able to respond to multiple stations
in a single slot (6/7/8 names)
: same band occupation with more names?
Thank you
Carlo

Carlo, Fox can not answer to 'multiple' stations, Fox replies only to two stations in 5 and in 7, see wsjt.sourceforge.io/FT8_DXpedition_Mode.pdf page 2 77 bit payload details, see wsjt.sourceforge.io/FT4_FT8_QEX.pdf page 7, table 1, message type 0.1 73's Wolfgang |

The Fox can send pack all the information for RR73 for one call and an R-XX signal report for another into one message.
Just enough room to do it. No real magic there....

thank you thank you dear Wolfgang
I'm trying to figure out how to get many calls in the same slot
in practice the first 0.1 bits "open" the way to more report
why does he talk about 8 possible types? I count 10.
I continue reading, but it's not easy for me
