  • This is only guess and speculation

    1. visibility. When its wet enough for the full wets, the drivers can’t see well enough to be safe. They are not going to slow down just because they can’t see.
    2. general safety. When it is wet enough for full wets, the cars are so low they can still easily aquaplane unexpectedly.
    3. the show. If its wet enough for full wets, they’re going to be fighting more with the car than each other and the spray will make the cars hard to see.










  • RF only has 2 components, Phase (frequency) and its amplitude. For Analog FM radio, you have a center frequency you tune to. The variance from the center frequency (phase) is the amplitude of the carried signal. For digital signals, you will have specified offsets from the center that represent specific binary codes.

    Edit: as others have said, the tuning and demodulating are 2 different steps. Step 1 tune, When you tune you take the signal centered at the carrier, what the dial on your radio says, and recenter it at 0. Step 1 is the same for pretty much everything RF. The output is “base-band”. You aren’t going in and out of tune because for each center frequency, there will be an agreed variance (band width) allowed for the channel. The tuner captures this entire range and this is what is then demodulated in step 2.
