[Elecraft] SW broadcast to calibrate against.

[David Ferrington, M0XDF]

Sounds like I can only just hear 50.050 and not good enough to zero-beat to
(I'm in a dip here, don't know if that's affecting it), might be better
later.
K3 doesn't do 70.05 MHz.

I've used 7.2 MHz for now, thank you all you made suggestions etc.
