Even before your post id asked a guy in a grow shop about this and he said that it was true but was corrected almost straight away' it was probably the 1st ever ones produced' im not into electronics so dont know what sort of signal they put out but it was detectable'.. besides i havent seen a tv decector van on the streets of the uk in about 25 years'.. lol the high fines and threat of prison if the fines dont get paid make people buy the licence so no need to send the vans out anymore...
