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

IMHO, small interconnections, you need both sides ground. Earlier in telecom we used balance twin wire cable with shield. ?There we used to ground at one? end and? if some one grounds at both ends, the shielding was lost and some longitudinal current were said to be flowing through shield . In such cases, only one side Gnd was recommended. ? But here the shield is a return conductor also.

I assume one coax with shield to ground at both ends - unlike the RF gain control coax, which is two coax cables, grounded at the pot end but shields not connected at the AGC board.? Let me know if that's not right.
