I've had 'tangential' dealings with Ofcom and yes, they have much bigger fish to fry than regulating what goes on on medium wave below about 1 watt ERP, although I doubt they would never put that in writing. They are a perfectly reasonable lot who have to prioritise their work.
Of course they wouldn't ban all test oscillators that operated on MW even if you modulated them - and most of them you can - unless you erected an efficient aerial or connected it up to a linear amplifier and could be heard around your neighbourhood. Even then you'd have to be: a) interfering with a legitimate station and: b) get reported by an irritated listener before they took an interest. (I'm not even sure MW is still a 'protected' service; i.e. if you complain about interference to a MW station would they investigate?)
As long as one keeps these devices as no more effective than a signal generator with a range of a few yards, I really can't imagine Ofcom taking any interest at all.
Nevertheless, if anyone wanted to sell ready-made devices with a range of a few yards, I think any advert would probably need to appear in very specific publications that only we'd read, rather than plastering them all over ebay for example!
