[TenTec] Century/22 AGC mod: urban legend?

[genewill@ordata.com (Gene A. Williamson)]

        I've chased the C/22 AGC mod to reduce "popping" all over the Internet,
but haven't nailed it down. Neither, apparently, has anyone else.

        Does such a mod exist? I can make do with riding the RF gain, but 
that's a
bit too much fiddling. The ARRL reviewer was ga-ga over the C/22's AGC, so
maybe I'm missing something???
