… just my five cent
→ blaming the airspy this way wasn’t 100% correct as a testing via splitter in my own testings was bad
→ blaming a customer this way is silly and helps nobody
→ for my testings i used two selected same antennas from jetvision parallel that produced same output within 1-3% range.
→ always did two runs for a week or so antennaX/receiverX and antennaY/receiverY then antennaX/receiverY and antennaY/receiverX
my findings were
→ habamp+nooelec dongle in combination with dump1090-mutability is nearly unbeatable for the price
→ airspy software can’t compete with dump1090 and raspis are too weak for airspy data output
→ airspy and especially radarcape are faster in detecting an aircraft for the first time but they deliver only few aircrafts more if any
→ radarcape delivers higher message rate (20%) than habamp/nooelec combo mentioned above
=> the only thing i’d find really interesting would be fpga solutions like this thread if their software would be on the same high level as dump1090 …
