Anyway, the tablet-PSK woes were not the only ones on this disappointing activation. My radio-controlled clock seemed to freeze, and needed to be restarted. I did this, but this particular model seems to take an incredibly long time to latch onto the LF signal (I'm not sure whether this model is listening for the 60kHz signal from Anthorn or the 77.5kHz from Mainflingen). Anyway, it did find the correct time - but only well after the activation!
I also had problems with the speed calibration of my Palm Code Cube. Again. Even with the dial on the lowest possible setting, it was still motoring along at about 30wpm, which is rather too fast for my fingers, let alone the ears of the chasers. Well done to those of you I worked, and apologies for anyone that I was too fast for. Of course, back in the shack, the recalibration procedure worked perfectly first time! Three attempts to do that on the summit all failed.
