Noisy Dish

[pedruid]

I had a PVR installed at end Nov and so far am pleased with it except for fiddly fast forward on remote.
On a few occasions especially on a Sunday when it's been on all day I get a noise like a swarm of crickets being emitted from the dish.
I have explored with a torch and could see nothing. This has happened as recently as yesterday. Ok during the day when the set is only on infrequently.
I spoke to the installer in PE who replied that he had never heard of this occurring.
Any Forum members experience anything like this?

Definitely sounds like something to do with nature; some sort of insect. Spray some doom!
