The previous repair lasted for almost 9 month. Today the Power over Ethernet (PoE) hat from pi-supply.com that is powering my ADSB receiver died again when a thunderstorm was passing overhead. Like last time, no direct lightning but according to weather monitoring we got several >150kA flashes within 3km distance. As a result, again, the DC-DC converter Silvertel AG9805-M on PoE ceased to work. This time no short on the inputs, but no output voltage. Even having some more spares add hand I decided to replace this converter by a TDK CCG15-48-05S. This one has a higher input voltage tolerance, up to 75V and hopefully a better surge protection. Let’s see how long this last.
Just modified a Raspberry Pi 3 to accept an external WiFi/Bluetooth antenna via U-FL socket.
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.
