[Elecraft] This will effect pilots and Hams throughout the Western US

[Michael Walker]

If it is a concern to those with the K3EXREF, what happens to their
frequency stability?

Are they now off frequency?  What is plan B if your K3EXREF reference fails?

Does this even affect those?  If it does, than I am sure it will affect
most cell circuits as well.

Just curious.
