Hi Gang,
So, got the SW Radio, and have found some interesting RFI sources around the house, have suppressed some, have a tech call in on another (the cable TV line has HORRID noise on it low, and if you lift it off the ground, has about 50volts potential to ground (yes, it'll draw an arc!!!))

One odd thing I found - every keyboard around the house (and I have different brands from cheap to Unicomp Model M keyboards) has horrid RFI _IF_ you are close to it (like the hand held within say 6-9 inches)

Any clues to a GOOD keyboard that doesn't broadcast like mad (they are all wired USB keyboards)
