COR LED shows application of new balance and phasing compensation

Scanning capability active with FCD installed and running

RTY scope mode added, with RHI (RTTY Hi Range Center F) button

CAR scope mode added, shows slow detail of carrier freq

All sliders now respond to mouse wheel with +/- 1

2.03 and forward will make new preferences settings

Some adjustments of initial defaults to accommodate new prefs

Mousewheel can now adjust left-mousebutton held demod edges

^ S reduces output buffer size (and latency). {bufsize} in info

^ L increases output buffer size (and latency). {bufsize} in info

"Troubleshooting" guide added to documentation

Two additional notch filters added, for a total of ten

Optional level-based squelch ( LSQ) or noise-based

Level-based squelch available for SSB modes

PEK control allows for either peak or average SMeter operation

SCP mode shows LSQ

squelch level

DNR provides three levels of Dynamic Noise Reduction

Memories now store and recall CW offset

Memories now store and recall Squelch level

Recall of squelch enabled by MSQ control, on

SCP mode supports mousewheel and leftclick adjustment of squelch level

Signal display area fonts are now on top of graticule

F and SFS adjust font size for signal display

Right-click on SWF sets the save directory for waterfall images

USCG/ITU distress and post-contact channels added to database

Time stations moved 10 KHz off-center tuning to avoid -80 dB IQ spike with SDR-IQ

Sideband BW increased to accommodate SW/BC DRM transmissions

FM BW increased to accommodate satellite APT transmissions

New grid spacings: 2,4,6,8,12 and 16 horizontal divisions

ZRO indicator shows spike reduction is calibrating

Waterfall time markers documented

Spectrum peak tracking documented

Fixes

Fixed up some tooltips I missed

crash on exit with record or save waterfall on

low-level networking bug corrected, was cause of random crashes

signal display area frequency display accuracy improved

Tooltips on +/- span were wrong, said "memory"

Some work on playback behaviors; still not 100% there, but closer

With DLL on (log mode), Decay slider responded improperly to mousewheel

Some font-drawing issues within signal area

Bandwidth limits not being obeyed on demod edges

Known Issues

You can set the demod frequency way off the center in 2.03. Don't do that.

dB level of playback and FCD are uncalibrated

Windows Only

FUNcube is cranky about sample rates on my VM. Don't have real machine to test with.
