Have recorded a new range peak in dump1090 running the Mode-S Beast together with a G7RQG antenna – 488km.
Finally got my spare parts for the Raspberry Pi PoE hat and put the ADSB receiver back online. It took DHL Express almost 6 days for the customs clearance, was the last time I used this carrier. UPS is way more efficient on that.
I used the outage for an upgrade to the Mode-S Beast receiver. The performance of the neat little thing is astonishing! Compared to RTL-SDR dongle the ADSB message rate is 3 times higher, I see 40-50 more aircrafts, tracks per hour increased by 300-400, range increased by around 70km and CPU usage is down to 2-3%. That´s with the G7RQG antenna, connected by a short coax cable (<1m).
My dump1090-fa fork now supports the Mode-S Beast directly via USB. See Github for details.
I took the opportunity for some experiments with gain settings in dump1090-fa while testing a new built antenna for the ADSB receiver. I compared my previously built QFH antenna to a G7RGQ omni directional antenna that I built last week. Second object of test was a 10m active USB cable (from Amazon).
