Re: Channels and Frequencies
Too late, and unrealistic, but since it doesn't really matter what the frequencies are, they could all have had a sequential number instead of the actual frequency.
With four digits there are 10000 combinations, far more than there are frequencies even at 8.33 (2280, less the ones unused around 121.5). If it had been easy with a letter, it could even have been 2 numbers and one letter, like "change to Kilo 2 9". But then a dial with 25 letters makes it too complicated.
But with 4 digits 0 to 9, we could have saved two digits, but unrealistic, because think of all the work and hazzle, changing all these aircraft radios!
