Made 2 flights with G_DENS (40263C) on 15/11. Track file shows reception from targets with ACSBP and U, so clearly 860-band reception is working. However there is nothing on Vector or PAW Playback. Any suggestion as to where the fault might lie? All was working for previous flights on 9/11. In an earlier message I had indicated that track files showed occasional breaks though PAW Playback did not. At the Bristol Strut meeting last week Ashley suggested that the SD card may have problems so I am about to try out a new one.
