..04uV is half the signal level of .08uV..........................see what I

The minimum discernable signal on the HF-150 is 0.08uV on all ranges
when
the preamp is switched off, improving to .04uV when the preamp is
engaged.

Could this be the other way around? The radio should be able to
discern a weaker signal with the preamp on, n'est ce pas?
