Hi,

As apparently WWV doesn't transmit up that high in freq., what are some
good "freq. standard" signals to use for calibration in the vhf/uhf ranges ?

Thanks,
Bob

What could be used as frequency standard "plucked from VHF" is the TV line
frequency.
I'm not sure if like in Europe, all TV stations in the US would be equally
useful but if you enter this search string in Google

you get several links that suggest it might be the case.
