How to use kiwirecorder to record waterfall history
I would like to study the performance of the antenna at KPH and to do so I would like to record the 0-30 MHz spectrum over 1+ hours while changes are made to the antenna and RF transmission system.
It seems that kiwirecorder.py -wf -z0
might do that, but I get no console or file output when I run that command.
Can you suggest how I could achieve my goal with the Kiwi + kiwirecorder?
