Stan,
I have used several amplified speakers with the SDR1000. Most have
required ferrite cores (F114-77 from Palomar or Bytemark) on the power
and signal leads to get rid of the RF when using high power. Currently
I am using the Altec Lansing VS2220 speakers available from Office Max
for $30. These speakers have the AC power supply built in instead of
using a wall wart and seem to be immune to high RF fields with no
ferrites needed.
Hope this helps.

Hi gang.
Just tried to run the SDR with some power (1KW or so) and got lots of feedback through the PC speakers. I then tried it with headphones.....not as bad but still there.
So...anyone else have RF issues? What is a good speaker(s) to use with the rig? I am using the FireBox by the way. I know it says to use amplified speakers in the manual, but it seems to me that amplified speaker would pick up more RF????
Thanks for input,Stan
