Hi Bob,

Yes, for the "usual" use cases it would work. But unfortunately a QSO on
UHF/SHF can be considerably longer (3-5min) than what Win-Test
"expects", so what you hear in Play-QSO is just the end of it. You then
need to rewind to the beginning of the QSO -> crash.

Note that I find the features of the contest recorder absolutely
marvelous (especially the way to extract QSOs) and I did not expect to
be able to play QSOs of different stations from one merged log. But this
part works well indeed.
Also the support for time codes is well done.
So the part that crashes is probably (I hope) easy to fix and would make
a great feature really complete.

Perfect, that is an option I was already looking for.
I'll have a look.

Yes, this is what you need. Unfortunately not enough for me (as I wrote,
I still need to rewind a bit to get to the beginning of the QSO).

Yes, no problem. I'll share a link with him with detailed instructions.

No, of course just ff/rewind in the current recording. Anything else
would be too complicated and too confusing.
