Bob,
I switched to pyhw. I do hear something that sounds like cycling.
I played a wav file (ssb.wav from flex-radio) with xmms feeding qjackctl
and then jsdr.
(On jack I connected alsa-pcm --> sdr-xxxx & sdr-xxxx --> alsa-pcm.)
I then started my sdr-1000 and shut down xmms. I also started python and
cmdr.
On pyhw I executed.
execfile("sdr1k-setup.py") (with setDDSFreq(0.810)
On cmdr I executed.
setRXOn 0
setSampleRate 48000 (I am using a SB MP3+ USB soundcard)
setOsc 0
setFilter -3000 3000
setMode AM
I didn't hear anything interesting - just something that could be described
as cycling at about 1 Hz.
Seems like I should have to do something with the qjackctl patch panel to
connect up to the sdr-1000. When I used it with the sdr-1000 it was set
up the same as I had it with xmms.
I know I should just wait for the new code but this seems soooo close to
working.
Thanks,
Everett, KG6RYB
