i remember years back thre was a small accident about a quarter mile away from mine, up near my mates house.
I could vaguely make out the glow of blue lights through the trees out of my window, but being about 8 years old at the time, i wasnt allowed to go and see what happened so i rang my mate.
Just as it started ringing, i could hear the policeman talking to his base on his radio, but i was picking it up on my phone, he was saying something about being in attendance at a car that rolled into someones garden, and there being no injuries and stuff.
When my mate answered i asked him what happened and he said that some bloke had indeed rolled into someones garden.
I spent ages wondering how that happened back then, must have been interference i guess.
I also used to be able to talk to the girl next door on my house phone if i was stood in the right place in the hallway and she was also on their house phone.
We had those wireless ones that you could take anywhere around the house and so did next door, so they must have been on similar frequencies.
My bro in law can also pick up someone elses baby moniter signal on their baby moniter as they must be on the same frequency.
