said in alt.radio.scanner:
Still the signal had to
be 100 microvolts to break squelch.
But how much to quiet the receiver to a noticeable amount, say on 150
MHz? In the tens of microvolts or around a microvolt (or less)?
IOW, is the receiver sensitivity bad, or is the squelch circuit bad?
Once you've localized that there are other tests to perform. For
instance, if it's the squelch, see if the high-pass network (usually a
cap and a resistor) is functioning.
