Hi all, This is a rather long thread and I am not sure how relevant this response is, but I'll risk it anyway. I use headphones 99% of the time, but when I need speakers (as when I want other people in the shack to listen in) I use a pair or of amplified computer speakers by JBL that came with some computer I bought several years ago. They are pretty decent (you can see them on my QRZ.com picture) but poorly shielded as expected. They are connected to the computer sound card's line out and the computer's line in is connected to the K3's line out. This is very convenient as I don't need a separate pair of speakers for the radio. If I key up a 5W 2m HT in the shack they hum like mad. But I have no interference in them from my HF rig simply because my HF antennas are sufficiently far (not terribly far) removed from the house and are balanced. It seems to me that if you have a serious problem with RFI into the amplified speakers in your shack, you are also going to have RFI into your (poorly shielded) stereo system, TV, telephones and just about any electronic device in your house (and your neighbor's house).
