Of course ... it's been a few years since dealing with that on a
regular basis.  ATSC is a whole different beast <G>.

In any case, that puts the W1AW code practice comfortably close
but just out of range of the "beacon".  I seem to remember there
were even articles about building a "W1AW locator" using surplus
color burst crystals.

Actually, you're a wee bit off there. It's 3.579545.4545... a number
burned in my memory from my TV repair days.

If you have a lot of time on your hands, there is a discussion of why
it's such an odd number:
