generating waterfalls from rtl_power?
« on: June 12, 2018, 1534 UTC »
Hi all.  I'm looking for mac software to generate waterfalls from rtl_power that are more interactive than some of the unix packages.  The rtl_power software instructs a RTL-SDR stick to perform a power scan across a frequency band and log the data in a csv file:
(date, time, Hz low, Hz high, Hz step, samples, dB, dB, dB, ...).  There are several ways to generate a heatmap from this data, but the ones i've gotten to work are all static...that is they generate an image file and you have to estimate the frequency of any 'blips' you see in the data, and you can't subtract out a background scan to account for computer noise and noise from the RTL-SDR itself.

Any suggestions?  Thanks!
Robert

p.s.  what i'd REALLY like to do eventually is have the RTL-SDR act as a reactive tuner for another SDR....
