f4exb	ce60c0b53e	Corrected timescale of waterfall when spectrum is SSB	2015-06-12 02:49:29 +02:00
f4exb	26b9c324e7	Improved GNU Radio plugin usability. Removed osmosdr completely from the build as it is superceded by GNU Radio	2015-05-18 02:18:33 +02:00
f4exb	3f106ade9e	Working unoptimzied WFM just mono (AF baseband)	2015-05-15 11:29:41 +02:00
f4exb	8948928ca0	NFM demodulation without using atan and smooth squelch with AGC suppressing most clicks on low level signals and hiss on carrier tails. Only useful modulation comes through	2015-05-14 17:19:06 +02:00
f4exb	d395ba24c7	Make the low cutoff frequency of the SSB filter variable. Change spectrum overlay accordingly.	2015-05-12 21:50:02 +02:00
