Software for Hermes Lite sdr radio
It has a number of interesting features:-
Spark sdr runs on windows 7,8 and 10, it requires .net4.5 and the visual c redistributable for visual studio 2013 32bit version https://www.microsoft.com/en-us/download/details.aspx?id=40784
It is currently restricted to only work with the hermes lite as I would like to get it working fully with one radio before supporting others.
Fixes current calibration on Hermes Lite 2.
This image shows the software working with a 32 receiver bemicro CVA9 Hermes Lite with 30 virtual receivers decoding wspr, JT65/9, psk and ssb over 10 bands using 13 hardware receivers .
This image shows the software working with a 2 receiver bemicroCV Hermes Lite with 5 virtual receivers decoding wspr, JT65/9 and sstv over two bands.
Fixes issue with panafall on 4K monitors.
Hermes Lite V2 temp and current readings added and time limit removed
Manual power series rx linearity correction
adc dbfs meter added
Hermes Lite 2 new gain setting supported

wspr and JT65/9 decoding spread out more to avoid cpu load peaks.
Crash on closing a psk decoder fixed.
wspr and JT65/9 agc made more efficient.

Rf gain limited to 19 on transmit.
Improved agc on JT-9/65.Version 0.132
Basic S meter added.Version 0.131
Undersampling transmit usb/lsb corrected.Version 0.130
Undersampling fixed (broken since v0.116).Version 0.128
PortAudio tweak to fix problems in some locales.
Start of movement of dsp code to what will hopefully become the open source version.
Many performance tweaks.Version 0.125

Fix for jt65/9 date bug in non utc timezones that caused spot list to be wrongly ordered.Version 0.122
Separate tx gain control and gain setting made smoother.
JT65/9 cancel button added and own tx colour changed. Own tx inserted if not received.
WSPR/JT65/9 default zooms tied to sample rate.
WSPR/JT65/9 data grid sorting fixed.Version 0.121
JT65 tx coding bug fixed.Version 0.120
JT9 & JT65 support, requires wsjtx 1.5 installed in default location.
Bug fix for wspr and JT9/65 for users with spaces in their windows username.Version 0.116
Virtual receivers added so you can have as many receivers as fit in the bandwidth covered by hardware receivers.
Higher zoom options with low memory usage.
Number of hardware recevers set from discovery packet.Version 0.115
Higher zoom options removed due to high memory usage.Version 0.114
Discovery with multiple network interfaces improved and network cpu usage reduced.
NFM mode added and fm modulation implemented.
Red tuning marker added to panafall.
Reduced cpu usage at high bandwidths.
Higher zoom options to allow wspr traces to be viewed at high bandwidths.
Alternative screen layout option under settings/display that only displays 1 receiver full size at a time. The old multi rx option is still there.
Summary display only shows when more than 1 receiver.
Tweaks to help with current early gigabit firmware.Version 0.113
Panafall Sliders made visible after bug in 0.112 hid them.
Logging of audio startup errors.
Ability to remove receivers added to receiver ... menu.
More space between buttons to make touch easier on small screens.Version 0.112
