THE GRAND NATIONAL.
Temporary sets were erected in thousands of offices for the reception of the running commentary on the Grand National. I penetrated into one West End office in time to hear this most successful broadcast on a real "Heath Robinson" crystal set, states a writer in an English journal. A wire had been slung out of a window for an aerial and the* set consisted of a few turns of bell-wire on a roil of cardboard, and a crystal detector. Someone had forgotten to bring a “pukka” set, and as everybody else had brought their headphones something had to be done about it. Bell-wire was produced from an old store cupboard and some bright youth found a small piece of crystal in his pocket! A drawing pin and a couple of paper clips completed £he set, which gave satisfactory signals on six pairs of headphones!
