Well, best of luck with the VOT. I am off again next Friday and plan to listen again through the sked because it really is a very interesting cat and mouse game, and it's interesting to try to imagine what everyone out there is thinking. From my notes, a typical patten has the VOT coming on a freq close to what is sked, then a couple of minutes later, a carrier comes on 1 or 2 kHz away from the VOT. Most often, the FD audio will come on shortly after, but in some cases it seems like the technician never turns on the audio, and this creates a hole for possible VOT reception.
I really wasn't aware of the whole concept of sync'ed audio on multiple FD channels, and I agree, Token's pics are way cool.
