|Maybe I'm missing the boat here, but I'd like to understand why our radios don't use signals from GPS or WWV. Lots of low cost consumer electronics does.
Instead of a TCXO, for example, a radio's frequency reference could be derived from GPS or WWV. If those signals were unavailable, then the radio would use its internal reference.
Similarly, why don't our radios include a clock, which would also derive the time from GPS or WWV ? And again, if those signals were not available, then the clock would revert to its own internal crystal.
Seems to me that both features would be easy and cheap to incorporate. Are there technical issues that I'm just not seeing ?
Thanks in advance for your thoughts and for educating me.
