I have always found the VHF definition to be strange, as it seems that a
uniform rule is better.

My impression is that the K3 and KX3 use the -73 dBm reference even on
6m.  Is that right?  What about with transverters - does one have gain
calibration?

Obligatory Elecraft comment: it would be really nice to be able just
show signal strength in dBm.
