I know there may be better places to post this, but the smartest
hams hang out on this reflector & I need advice, so here goes:
My neighbor 300' away had an Aptiva 120MHz pentium. No matter
what I did, I still got into her computer speakers. Being a good
ham (let's pretend I didn't notice her long blonde hair, ok?) I
offered to come up with a solution. With that in mind,
I put .01 caps on the speaker leads, wrapped the speaker
leads around RF choke torroids, and put a brute force telephone
filter on her modem. But the speakers STILL picked up my ssb and cw
(I run 200w out...3 el Quad up 60'). I even switched out speakers
and have had the same problems. The good news is...
...in the meantime, she fell in love with me, moved in, learned the
code, is taking her Tech Plus this weekend...and we are getting
married in July!...
...but he bad news is I still haven't found a solution to the Aptiva!
Does anyone have any experience with this pc...and what I can do next?
As you can see, I'll go to any extent to get this problem solved... :)
