For some time I've been meaning to place a barrier to unwanted RF (Radio Frequency) energy in the mains power supply to my Amateur Radio station. The object of the exercise is to prevent RF noise generated by local consumer electronics from getting into my receivers and masking the signals I'm trying to listen to. Also it should prevent stray RF signals from my transmitters being carried by the power wiring and causing problems.

A few weeks ago I actually bought the ferrite cores needed to do this and today I finally managed to build the choke into the power lead.
