Hello Scott,

I assume you can hear the interference on the SSB's speaker when the
power brick is operating?

I also assume the laptop is connected to the SSB via a serial port (or
equivalently, to a TNC which in turn is connected to the SSB).

If yes to both, try disconnecting the laptop from the SSB/TNC to see if
you still hear the noise.

If the noise goes away, then Meindert's suggestion may help. You can
find clamp-on ferrites at Radio Shack. Use several turns per the
instructions. It would be best to install at least one on the serial
cable just before it connects to the SSB. Ideally, that would choke off
any RF on the cable.

If the noise is unaffected, the interference is probably being radiated.

If you are using the laptop's internal soundcard, then the audio lines
to and from the SSB should also have ferrite chokes.

Running the laptop on internal batteries should completely solve the
problem (while adding another, of course).

Good luck.

Chuck

I've just installed an ICOM 802 in my boat and today found that the only way
to get clean noise-free weatherfax reception on my Sony VAIO laptop is to
disconnect the "power brick" and run the laptop on batteries alone. There
are some other interference sources, especially the radar, but the laptop is
the most inconvenient problem at the moment. Any suggestions as to how to
reduce or eliminate RF interference from a VAIO power brick?
TIA,
