| c. Hs.{Lord Ernest Hives - Chair} c. RECD NOV 26 76008 Rg{Mr Rowledge}5/DM.{D. Munro}25.11.31. We have been interested for some time in battery ignition and interference with wireless. We understand the London Police use battery ignition on their motor cars and also are able to keep in wireless communication whilst the vehicle is running. We are curious to know how the screening of the wireless is arranged and what arrangements are made for the supply of current to the wireless set. We wondered if you could get into touch with the Authorities at Scotland Yard and obtain some information for us. If you could arrange it we should like to send our Mr. West up to Town for you to introduce to the right people. Rg.{Mr Rowledge} | ||
