Hey Glyn, no I have not seen one yet! Im only 23, so possibly a bit too young to off seen them active?
PS, got your PM on here earlier no problems, all sorted now. Thanks for ya offer - was the connector at the end of the supplied coax. Its on its last legs but with a bit of a push the inner core portudes just enough to make a decent connection. It just cant afford to be nocked or pulled. Hopefully purchasing an external antenna soon anyway.
