[Elecraft] K2: IDing Rev B Boards

[Jeff Hetherington]

Hi Everybody.

Now that the KX1 is up and running, I can move onto my second hand, but
unbuilt K2!  Included with the unbuilt K2 was the complete Rev A to Rev B
upgrade ... and I see the RevB markings on the Control and FP boards ... but
not on the RF board.  Is it marked somewhere that I am just missing ... or
is there another way to tell the two RF boards apart?

Thanks.
