What wattage is the OP going to use for that 75ft range? just a guess?”

About a microwatt, do the maths,

1 microwatt gives 50 dBuV/m (enough for clean mono) at 20 metres
It's really not worth worrying about, any spurious emission (assuming a totally crap design) will be down on that level, which is why Ofcom made such devices licence exempt. Other domestic appliances kick out just as much level, all over the spectrum, and the world hasn't stopped turning.

Yes, of course if someone reports it, and there's always someone that will, so best avoided on those grounds. It'll be way down Ofcom's list, if there is any prosecution it'll be from the PRS I suspect.
