17ac99344c For now, change to BT=1.5 for FT8. This commit enables the waterfall analysis window. This decreases sidelobes significantly in exchange for increased noise bandwidth. Sensitivity to weak tones will be degraded somewhat. 2019-02-23 14:18:22 -06:00

fd7bca080a Revert to direct Log QSO invocation rather than deferred for Fox logging 
Deferring using a 0mS timer does not work for Fox logging as it may be
invoked  more  than   once  in  a  loop  when   multiple  streams  are
active.  This change  directly  calls the  logging member  function(s)
inside the message processing loop.

This change  was initially  made because  an unhelpful  database query
order along with a need to display the latest logged QSO at the bottom
of the  Fox log table view  was causing GUI unresponsiveness  when the
Fox log table had many rows.  The current implementation shows the Fox
log table view in descending time  order with the latest logged QSO at
the top  which avoids this  unresponsiveness issue (tested with  a Fox
log table with over 15,000 rows).

71cb6d9f50 Use 4 different Costas arrays to prevent false syncs as received frames move 
through the analysis window.

Add a random 77-bit vector to each message so that tone transitions occur
even if the message contains a long string of 0 or 1 (like a CQ).

Add alternative sync calculation as an option (sync2), for testing.

Add basic framework for AP decoding.

4dfc4685e9 Make the UDP protocol Clear (3) message two-way 
External servers can clear either or  both of the Band Activity and Rx
Frequency decodes windows. This was  requested by Dave, AA6YQ, so that
DX Lab  Suite applications can  clear old  decodes on band  changes to
ensure that decode highlighing is consistent.

846918e3aa Remove normal mouse double-click action for decode display windows 
The normal  action selects the word  under the mouse pointer  and this
disrupts   callsign  highlighting.    Normal  single-click   selection
behaviour is unchanged  so text can still be selected  using the mouse
and copied if desired.
