Interesting reading..
Well, the think that leaps out at me is in appendix I section 7 of the report, where the chaps at PA consulting cheerfully mention they received the interfernce from their single reference PLT installation ~70m away, re-radiated from the overhead feedlines. Essentially, in a built up area, radio use would become impossible if most houses had something like this, as like rats in the drains you'd never be far from either one or the next.
I really can't help but believe that either money talks, and someone profits a lot from looking the other way, or more sinisterly there is a hidden agenda to discourage folk from listening to anything other than strong local radio stations, smatterings of the sort of behaviour we used to pity the eastern bloc countries for.
For what its worth, I understand the Comtrend kit was CE approved, based on inspection of a technical construction file, rather than laboratory testing, and granted by a Spanish approvals house, using (or mis-using) levels taken from a draft copy of a PLT standard that had been withdrawn as unworkable without ever being ratified.
Oh dear, here I go again.
Mike.
PS A big reason there aren't complaints of reception from greater distances is dificulty in being sure where it is coming from until close. If anyone wants to build a PLT network with a filter that is switched in and then bypassed with some recognisable code (sending "P_L_T" in morse perhaps) real range tests of an individual unit would then be possible by listening to the modulated noise.
