Why would OCUK close your threads?
I have said it before, many times, I will say it again.
OCUK Forum is run by a bunch of humourless Nazis which is why I've never, ever, displayed an interest in taking part in their community.
All they're really interested in is sales, they don't like dissidents on their sacred forums
And yes, those guys were right, you do need a special kind of sounder to emit high frequencies, an I-Phone or normal loudspeaker just couldn't cope with a 60Khz signal.
