LF HF Antenna noise reduction experiments. Deploying Ferrite clamps and mast earth.

With thanks to the members of Facebook group Non Directional Beacon chat and https://groups.io/g/ndblist.
QRM man made noise or interference has become worse and worse over the years especially since Ofcom gave up on enforcing against cheap and nasty electronics like PLT and Switch mode power supplies.
As ever I've been looking for ways to reduce the noise so I can carry on with my hobby.
Here are some observations that seem very positive for adding simple clamp ferrites at the mast end of my two antennas.
