[Ham-Mac] RFI getting into computer

[Richard Hemingway]

Hi Group,

I am wondering if the plastic casing of iMacs is more susceptible to 
RFI from the antenna than is a computer with a metal case.  However, 
I should explain this.  I am in a r etirement apartment and have my 
antenna sitting on top of a bookcase about 10 feet away.  I am using 
a G5 with a metal case, but the monitor has a plastic casing. If I 
don't  have the display angled properly RFI will cause the computer 
of turn off and on.  I also have a Toshiba laptop computer and RFI 
never bothers it at all. (I should say that I only use about 30 watts 
with PSK).  I have disconnected the display from the computer and FRI 
doesn't bother it then.

The problem is that I am thinking of buying an iMac Inter Dual Core 
computer.  The casing is all plastic and I am wondering if the 
problem would persist.  The PowerBook has a metal case (I think) and 
I don't imagine would have t his problem.  However, I would much 
rather have the iMac.  Before you all jump in and say so - yes I have 
filter and chokes all over the place and on all the cables.

I ma not experiencing it as much with the new Icom 756 PPRO3 I now 
have as I did with the Orion.

Thanks,

Dick, N5XRD
