Hello fellow RFI'ers:
I'm new to the list and looking for some assistance. I'm bleeding =
through audio to my
neighbors amplified speakers.=20
My station DR70T to AL80B running 800W SSB
GAP Vertical up 10' in my backyard about 120ft run from shack in center =
of house
All shack equipment (rigs, tuners, amps, accessories are all grounded to =
a central bus to gnd)
1KW Low-Pass filter. and Radio Works 4KVLI (line-isolator with tie to =
gnd also)
My house is clean with no interference in any device (computer or =
otherwise)
400 ft away my neighbor is picking up my 15m transmission at 100W and =
800W. Only difference
is it's louder and stronger at higher power. The pick up is through a =
set of computer speakers=20
connected to the computer. They are an amplified set of speakers, and =
signal bleeds through=20
whether power is applied to the amp or not. Common mode???
Anyway, I'll take suggestions on attempted filtering, but also =
interested in whether the=20
magnetically shielded computer speakers I see advertised are much less =
susceptible to
this type of interference.=20
Also if there are any brands and models this group of experts has =
experience with that are=20
recommended, I'd be most interested in that as well.
Thanks in advance for any help,
73,
