When I am sitting in a park or out on a snowmobile trail with my KX3 and my
laptop using a GPS for time sync since there’s no cell reception there,
anything that relies on the Internet will be basically useless to me. Why
would we aim to exclude a growing number of such users like me? Perhaps I’m
misunderstanding.

Subject: Re: [wsjt-devel] WSJT-X 2.0 possible new mode/protocol
Hello Joe,
.
It was excellent example with the WSPR QSO, just thought we can get additional
FT8 gain if some messages at QSO will be transmitted as 'hash hash' / 'call
hash' / 'hash call' instead of callsigns.
.
Yes, there is a trade off between the sensitivity and protocol flexibility.
Probably we can add more flexibility if some information will be passed over
Internet, for instance free text messages and GRID, it will spare more bits
toward sensitivity on the radio interface.
.
Other option is to pass some message's hash over Internet while transmitting
this message via radio interface, it will also spare some bits toward
sensitivity.
.
Proposed by Take JA5AEA variable code rate: we can pass information on the code
rate over Internet at the QSO, hence appropriate decoder can be used per each
message. The same approach can be implemented with the variable protocol where
protocol details, for instance i3bit, can be broadcasted over Internet.
.
Leaving callsigns(hash) and report to the radio interface and combining radio
interface messages and traffic over Internet in the FT8+ protocol we can marry
JT65/JT9 sensitivity and FT8 rate of QSO.
.
I do not believe any new mode outside WSJT-X is a good idea, it would be more
efficient to keep going in the common direction.
