v1.441: camping fixes, AGC CW threshold, audio FFT extension fixes, misc fixes
From the CHANGE_LOG file:
v1.441 March 15, 2021
Audio camping bug fixes:
URL redirect now respects URL camp parameter. More work needed for other cases.
Audio now plays on Safari.
Added separate CW AGC threshold control.
Typically a lower AGC threshold is required for very narrow passband settings to
avoid low sensitivity. Since narrow passbands are most often associated with the
CW/CWN modes it was decided to add a separate AGC threshold control active only in
those modes. The original threshold control applies to all other modes.
The two are stored in their own separate browser cookies.
Fixed bugs in the Audio FFT display (the one that appears in 8-channel mode when more
than two channels are busy, or if the URL "no_wf" parameter is given):
The LSB passband is drawn in the same place as the actual FTT output.
The FFT display bins were flipped to be correct (i.e. low vs high frequency).
Autoscale mode works better than before.
Disabled compression ("comp") button in DRM/SAS/QAM modes since it has no meaning
and effect in these modes.
Fixed shift-click in SWBC bands not selecting nearest 5 kHz boundary.
Fix long audio latency on browsers that display "Click to start OpenWebRX" overlay.
