Default Re: Cossor 524 rustling noise on FM

Right - it seems as though I hadn't got the whole story.

If I apply a 10.7Mhz signal to the grid of V2 the rustling is apparent until the volume control is turned to maximum when it is much reduced. Here is a YouTube link

If I apply an RF signal to the "live" end of the volume control there is no crackling
