And, of course, such a meter would measure at some frequency OTHER than the
HF frequency you're actually interested in.
I suppose one could do something like measure the received signal strength
from a fixed beacon, and keep adding radials until the difference is "small
enough".. Lots of traps here for the unwary, the vagaries of propagation
being but one.
