My Corsair has a pronounced noise peak around 2KHz (I've not measured the
frequency, so I'm guessing).  It's arising before the notch filter as I
can notch it out which improves the sound quality enormously.
 
 
This does not sound normal.  The product detector directly feeds the notch
filter.  My guess is that you either have a bad xtal filter or your rig
needs an alignment.
I've looked at the rx audio spectrum of many Corsairs and have never seen a
peak like that.
 
 
Thanks for the advice...I'll certainly take a look.  It's not a big
problem and I'm not sure when it first showed up.  I've had the rig from
new -  1988 - si it could probably do with a full check=up!
