Meter reading sounds low to me.  In theory, 0 dB on the meter  should 
correspond to 1 uV, 20 dB is 10 uV, etc.  So 100 dB should be  100,000 uV.  I doubt 
that most meters are all that precise, but it probably  should be within 20 dB. 
 I also get 40-50 dB on the calibrator signal. It  could be low IF gain, or a 
bad meter.  Are you sure you have original  meters in the radio?  Some 
substitutes lack sensitivity.
