Think Wireless 2.4 TV/monitor/xmitter.  Go to a test equipment rental shop
and rent a spectrum analyzer that works in the 2.4 range.  Connect a low
gain directional antenna to it and start looking for the direction of most
noise.  Then turn the antenna backwards and start working the null back to
the source.  When you can't null out the noise any longer no matter which
way you turn the antenna, you will be on top of the source.
