What's wrong with signal reports... lots of us like to know how well

But signal reports only tell us signal to noise ratio in the other
station's receiver, NOT signal strength. I use WSJT modes on 6M and
160M to make difficult QSOs -- (on 160M it's EU), so I run legal limit
to better than average antennas and on 160M, have two reversible
Beverages and two RX loops, but WSJT nearly always give signal reports
to the stations I work that are 10-15 dB better than what they give me.
So signal reports in WSJT tell me far more about their station and its
RX noise than how well I'm "getting out." And especially on VHF, if
you can eliminate one "over" by exchanging only the grid, or by
calling with TX2, we can squeeze 30 seconds out of a QSO and squeeze
one third more into a short band opening!
The only reason I call with TX1 most of the time is that I'm a K9
living in W6, and don't want the other station to swing their beam in
the wrong direction. I've lost QSOs that way. :)

Jim,
please remember that many WSJT-X users of the latest set of digital
modes (FT8, MSK144, FT4, FST4, Q65) do not have the luxury of being able
send grids in standard messages because they hold calls that do not
qualify as standard calls as defined by the protocols. Signal reports
require many less bits to convey than grid squares do and the source
encoding of messages takes advantage of that. If reports were dropped in
favour of grid squares the protocols would need fundamental changes,
including a loss of sensitivity, unless all those non-standard calls
were to be excluded from normal QSOs.
