Joe,
FYI, this isn't an isolated incident. Several hams, from NA, SA, VK and ZL,
working to exploit the December-January openings between the Americas and VK/ZL
have tried moving from FT8 to Q65-30A, only to have the same non-decode problem
appear. (I am one of them. For the record, watching terrestrial 6m signals
from VK on a waterfall that do not decode -- some at audible levels -- is quite
frustrating.) Q65 is getting a poor reputation with this group of experienced
VHF DXers. If you find a solution for Peter, please disseminate it to this
list.
Ed Callaway, N4II.

in passband
Hi Peter,
I tries WSJT-X 2.5.4 on the Q65 sample Q65 files. I see all the
decodes for Q65-60A and Q65-30A that are mentioned in the "Quick-Start Guide to
Q65," so I have no idea what may be causing you trouble. If you haven't
figured it out, you could send me a copy of file WSJT-X.ini in your log
directory, and I'll look further...
