Really? I thought that there were still frequencies that used digital, that
were not PCS, and therefore not legal to use in the air.

True, or not?

I had not seen anyone mention that PCS usually does not work above a couple
thousand feet, due to how the transmitter antennae were oriented. Is that
correct, or a myth?
