Nope. Remember the circuit has a good bit of gain so any change on the
input is reflected by a magnitude of gain on the output. My data stated was
from testing of the Omni VII using an adjustable bench power supply metered
at the radio connector with a highly accurate DVM for DC voltage measurement
and a Bird 43P for power measurement and a 50.5 ohm dummy load.
