My Corsair has a pronounced noise peak around 2KHz (I've not measured the

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!
