Hello Beat,
the only document I am aware of, is the
http://physics.princeton.edu/pulsar/K1JT/JT65.pdfThere is says: "Supported suffixes are /P and /0 to /9' , so there is no /mm or /MM
The prefix table is different to the one implemented in WSJT-X and it's help. (?)
http://physics.princeton.edu/pulsar/K1JT/ftrsd.pdf https://physics.princeton.edu/pulsar/k1jt/FrankeTaylor_QEX_2016.pdfWhere did you find a 'version 2' of the JT65 protocol specs?
Using JT65code.exe of the current WSJT-X and trying, as an example:
"CQ 3D2R/OE1MWW RH97" (I wish, I where there...) results in "CQ 3D2R/OE1MWW" and the locator is missing.
The same result will be seen, if I enter this in WSJT-X and try to transmit it.
The same will happen if I use 3D2R/OE1MWW/P or whatever suffix.
We have a saying in Vienna"nix is fix, alles ist möglich..oder doch nicht"
(nothing is fixed, everything is possible... or sometimes not)
Next days, I will try a setup JT65-HB9HQX 5.01 <=> WSJT-X and check, what each side understands
