Was picking up 101.2 down here in Sussex earlier but after every few seconds it seemed to get much weaker or completely disappear and then come back again and constandly keeps doing it, I noticed this a few days ago too.

...Is anyone else noticing this?

They have been like this a long time and I don't know why ?

From what I understand, a few months ago they updated their antenna system and although I would have expected their signal to have slightly increased with it, I infact noticed that it was a lot weaker and the fact that it's now started reducing power for a few seconds and coming back to full power means I expect the SWR protection kicking in...

They have had strong and weak and strong again for years now

I only noticed it a few months ago but I was sent a recording from over a year ago and their signal was doing the same thing...

And sometimes in stereo and only in the last 2 years for stereo
