Hi Warren, yes but its nice to see enthusiasm still on the LF bands even if
ol'farts like me keep on squelching them with "been there done that" :-))

Hi Alan,
    I have contemplated getting a US experimental license for 73kHz
but have decided (for the moment at least) against it.
I believe that I could get a license, in fact I think I could get one
license that covers 70-190kHz now that Loran is gone.
The problem as you have stated it wouldn't bring any new people into
the LF hobby, I imagine that a few of the usual suspects on this side
of the pond would give it a whirl, but at the expense of the already
minimal 137kHz activity. Also I find 137 challenging enough!
