Noticed since the weekend there is a very loud nasty hum on 87.5. Quite strong on the Reading online tuner and around Hampshire and Surrey and also heard up Beachyhead in East Sussex coast.
....Could most likely be UK's Finest but been doing this since at least this last Saturday. Fix up

I herd a test transmission for uks finest a few weeks ago and also picked up livefm on 87.5 rds shows livefm over the weekend

noise masker over fm, I suppose its easier to detect than a blank carrier good for dxers and knob fiddlers
