Oops. Well, I didn't look at the schematic. I assumed this to be true as I seem to recall having exactly the AGC problem I described which went away when I put in an 8.2 filter. Now I'm wondering if I dreamt it. Anyway, thanks for the correction guys and I'll crawl back into my cave. Moral: Check one's facts before trying to be "helpful". 73 de Jim (the chastened) Smith VE7FO
