I'm a new user of the AR9000 Rx and Flight Log device. Over the weekend I got some interesting data from the Spektrum Flight Log. On one of the flights I got over two hundred fades on A and B antennas and nearly two hundred for F (Fades), which resulted in 3 Holds. On another flight I also notice this reading "b ---" as I cycled through the logger. What would cause this reading? Also, when I get holds (failsafes), what exactly is happening to the Rx/Tx link? I didn't notice any loss of contact with my aircraft. I have not once moved my setup and have had flights with no more than 2 or 3 fades on any of the antennas.
