[Elecraft] dBV reading on Kx3

[Walter Underwood]

To expand on Lyle’s correct answer, the dBV reading is designed to be used as a relative measure. Read the description on page 22 of the KX3 manual.

I think it is really cool that Elecraft documents these internal receiver test points. I’m sure they exist in other radios, but they are undocumented, factory-only readouts. Does any other rig display PA temp, let alone oscillator temp?
