[time-nuts] Where 15 MHz?

[Bob Camp]

Hi

It turns out that 15 MHz x N (I forget the N) makes a nice LO in the 900 MHz range for an base station.  That's what drove the choice of 15 over 5 or 10 MHz. I believe there was a bit of the "all frequencies are equally cheap in your volumes" sales pitch involved as well.
