Thank you for the responses. My thirty-two year old tuner recently has some modifications and an alignment by a respected broadcast engineer and circuit designer.
Help interpreting tuner specs
These are the readings from my old tuner after testing: Distortion @ 1 kHz - 100% modulation
Left Wide IF mode 0.053% Narrow Mode 0.18%
Right Wide IF mode 0.054% Narrow Mode 0.18%
Stereo Separation @ 1 kHz - 100% modulation
Left into Right Wide IF mode 64 dB Narrow 57 dB
Right into Left Wide IF mode 63 dB Narrow 56 dB
65 dBf RF input quieting - unweighted (Signal to Noise Ratio)
Mono -72 dB
Stereo -75 dB
50 dB quieting points - unweighted (Sensitivity)
Mono 0.5 uV
Stereo 22 uV
Do these readings represent good tuner specs?
