Not that I would condone such activity, but there is a quick and dirty way to
monitor MDT's using a VAN ECK device and a Yagi antenna. Most but not all
MDT monitors are of the green or orange phosphor type and can be received by
VAN ECK devices up to a few hundred feet. The caveats of such monitoring are
obviously getting caught, you must follow the PD cruiser around or find a
stationary cruiser, or park a couple a hundred feet from the PD and try and use
it. Note: I have never attempted these courses of action, these are just some
ideas I have mulled over. I am currently building a VAN ECK device from plans
bought from Consumertronics.

I don't know the details of the VAN ECK device, but would it still work if the
police MDTs were using LCD screens instead of CRTs?  I know some MDTs do use
LCD screens instead of CRTs.
