For low level signals, I like to use one of my Tektronix 7000 series scopes and feed the frequency counter from the vertical signal out on the scope.  If you have a scope with a fairly sensitive preamp and a vertical output give this a try.  It also allows you to “see” what you are measuring.

Looks like I need frequency counter help, not R4-C help.  I just discovered my counter doesn't seem to be working correctly.  I checked a known aligned and working R4-C and get the same bogus measurements.

 

Thanks
