  I wonder if anyone has managed to do any harm to p.c. eq. by using high power r.f. close to the p.c. I have a dedicated loop aerial within 5 feet of my newly repositioned p.c. but have been reluctant to power it up even with all the ferrite rings that I have installed on the leads. I have the main aerial a doublet but the loop is connected to the large and very powerful marine tranceiver, ie low power is 100 watts, high power 250 watts. P.C can be such a pain in the .... at the best of times so I am being very careful....

 Well Tom it got you to reply, I'm sure there are enough broad shoulders out there to take it,compared to some of the banal postings I would have thought it was quite an interesting subject as most hams seem to have a p.c. in or near the shack. It was the near proximity of the aerial to the p.c. that I was most interested in, anyway not to worry.

Well, I've got a random wire running off the back of my tuner and it's only a few feet from my PC.  On some bands, I get audio through my PC speakers so I just turn them off.  Occasionally my PC itself will act strange if there is too much mike gain or if the signal is otherwise overmodulated.  It doesn't do any harm to the computer.  None of my other antennas cause problems other than sometimes coming through the speakers.

I run a laptop beside my TS-2000 and my antennas are very close, including a 40 meter about 5 feet away.  I sometimes get interference from the RF on the computer and it has actually changed the programming of my PSK software (MixW), but seems only to affect a program that is active, not the inactive ones, so I am guessing that the RFI is acting on the keyboard rather than messing with the hard drive or anything else.  I have this problem starting about 50 watts, depending on the band.
