Hoped to get a few P3i pings from aircraft visiting Expo at Sywell from the south, got three sets over two days, only one with #es in track file, which was G-URMS. The strange thing is that it shows as both G-URMS and GURMS, alternating in batches in the same way as ADS-B Reg-ID and Flight-ID. What is going on here, I didn't think PAW had a way of configuring both types of ID?
