In setting up ka9q-radio and ka9q-web I now have a working setup. With the nice browser GUI.
KA9Q-WEB has 2 issues :
 no audio -> to what audio device is it sendings its audio and can this default be changed
at the same time the monitor program streams audio loud and clear to -R 8 and other choices

 not a complete spectrum, depending on zoom and tune frequency
Some background, Fobos SDR for HF Direct Sampling has a maximum sample rate of 50 Mb/s and a frequency range of 100 kHz - 25 MHz.
(For RF it goes from 25 MHz-6000 MHz, max sample rate 80 Mb/s)

When the spectrum is zoomed from 0-12 Mhz it is continuous. When I zoom out 1 more step it misses the 12-13 Mhz band, that turns black completely. For the rest 0-25 Mhz is complete. Zooming completely in to 12-13 Mhz is (of course) again showing a continuous spectrum fro that frequency range.
