The Philips EE series of kits had reciever projects, but I don't think
there was a single transmitter. Many other kits did, indeed, have
low-power AM radio transmitter projects

I am pretty sure they were technically illegal in the UK (I don't know
about other countries ), but that given the very low range (you were
lucky for it to work across a room), and the fact it wasn't likely to be
in operation for very long, then the chances of getting caught were
essentially 0 (I certainly never heard of anyone having problems ffrom
uilding such projects).
 Although I remember a warning in the manual for one such kit which
was something like 'Connecting a long antenna to this project will
violate FCC rules'
Longer-range devices, used for longer periods, as here, are a different
issue, of course.
