Hi Paul,
there's only one bit per callsign. The protocol doesn't support both /P
and /R for the same callsign, neither does it support /P for one
callsign and /R for the other. Note only standard callsigns can be
augmented with /P or/R, and then only when used in certain specific
message type
Interesting to see how FT4 outperforms FT8 (by a lot!) in the high-latitude
moderately disturbed channel model.

If you're interested in how the FT4 and FT8 modes work, and how they are
implemented in WSJT-X, you can find all the technical details in a
paper by Steve Franke, K9AN, Bill Somerville, G4WJS, and Joe Taylor,
K1JT, published in the July/August issue of QEX.

Hi Rob,
WSJT-X v2.2.1 uses the following command line options for the Deep decoding
setting: " -C 500 -o 4 -d “. The “-d” option may be too intensive for
low-powered machinese.
You’ll notice that the number of Fano iterations is limited to only 500.
Testing here indicated that this virtuall
