Scanning for Jupiter 2014-03-30 23z through 2014-03-31 06:15z

For my next attempt to scan for Jovian emissions I plan to use 1/2 second time scans by 10khz frequency bins over 2.7Mhz with 700Khz overlapping frequency ranges between 4 RTL dongles to compensate for the edges of the scan having less sensitivity.

Here are some details, and in a subsequent post to this one sometime after the scan has completed I will post the GNUPLOTTED results.


(First Results - not impressive)

Setting the z-range (set zrange[-55:-35]) basically 'filters' displayed results by chopping off the low-lows and the higher than average highs (spikes) so that your eye can see the most subtle patterns or weaker changes.

Unfiltered with the zrange (dbm range)
