Yeah just do yourself a favor and build yourself a simple quick spider for comparison:
QUICK SPIDER - No Soldering, No Connector
Why don’t you let each stick run for at least a day or change it around midnight.
Then you can compare the bar graph (Positions Reported by Distance from Receiver) by selecting the data.
Just looking at the map it’s hard to see small differences.
I would be very surprised if the rtl-sdr stick really is better than the Pro Stick.
Are your using the FA filter?
