Re: RFI from uBitx TX after AGC and other mods installed

If the problem is feedback from the RF portion of the AGC board back to the AF input, wouldn't a ferrite bead on the Audio input at the AGC board accomplish the same thing without attenuating the audio any with another capacitor to ground ?  On the first pass of the AGC board (none were shipped out), I had a 470pF capacitor to ground but it caused oscillations .....apparently a 10nF capacitor does not, based on the work you guys did.(and thank you for the input) .
