[Elecraft] Is the Lab599 TX500 a "rip-off" of the KX3?

[John Harper]

As someone who has one of these radios on order, I'd like to know if this
is fake news or true fact:

"This rig is copied from the KX-3. I was told this from a reliable source
inside Elecraft."

Comments from Elecraft especially welcome.
