Many of you have been using WSJT-X 2.4.0-rc4 to test the new mode Q65 on
the EME path. Especially on the bands 144, 432, and 1296 MHz, we know
that some users would like also to be able to use MAP65 for Q65. Here's
a brief update on the development status of Q65 in MAP65.
I have now used my development version of MAP65 v2.9.0 to run through 46
one-minute recordings (saved *.tf2 files) obtained by Conrad, PA5Y, on
February 20. There was plenty of 144 MHz EME activity on this day,
including many signals in submodes JT65B and Q65-60A. This test version
of MAP65 2.9.0 decodes essentially all signals visible on the waterfall,
in both modes. The decodes include 161 Q6560A transmissions and 138
JT65B transmissions. (For JT65 this count omits the shorthand messages
RO, RRR, and 73.) The attached file Decodes_at_PA5Y.txt was extracted
from the file map65_rx.log produced from Conrad's files.
A good feeling for the behavior of Q65 in the present MAP65 2.9.0 can be
obtained from the following document that describes the use QRA64 as
implemented in MAP65 v2.7 and v2.8.

Except for the comments about "Sync Markers", you can pretty much
replace "QRA64" with "Q65-60A" everywhere in this brief write-up, and
get a feeling for how Q65 works in this early version of MAP65 2.9.0.
You might also want to look at the MAP65 User's Guide:
https://physics.princeton.edu/pulsar/k1jt/MAP65_Users_Guide.pdf
Further work remains to be done on MAP65 v2.9.0, but we hope to be able
to make a test version available to interested testers in the near future.
In the longer term, we are exploring possible ways to bring MAP65
capabilities including wide bandwidths and polarization diversity into
WSJT-X.
