THE WIRELESS WONDERS OF RUGBY.

GREAT EXPERIMENT WHICH WAS COMPLETELY

The Engineer-in-Chief of the Post Office was happily inspired when he invited the Council of the. Intitute of Electrical Engineers to juspect the great Rugby wireless station now at a definitely advanced stage of its development.

When two aerials' run close to- gether there will be interaction between then which will affect the selectivity of both sets.

B.B.C. CONDUCTOR

. RESIGNS.

Mr. John Ansell, conductor of the B.B.C. wireless orchestra for the last four years, has resigned and is returning to theatrical work.

My Ansell, who has composed the music for several comic operas, bal- lets, and orchestral pieces, was ap pointed musical director of the Al- hambra in 1013 and remained tuere in that capacity until 1920, when he joined Messra. Grossmith nu Laurillard at the Shaftesbury Theatre. Subsequently he was at the Adelphi Theatre and then must. cal director of the Winter Garden Theatre, where he remained until joining the B.B.C. in 1928. He was associated with a long series of musical comedy successry and com. posed the incidental music to all Mr. Cyril Maude's productions at the Playhouse,

EXPENSIVE ETHER.

Speaking at the Aldwych Club, London, recently, an official of the American National Broadcasting Company revealed that the charge for one hour of broadcasting time on stations covering the whole of the U.S.A. would be £2,000, and that maything from £300 to £1,400 would be spent on programmes to fill that time. He said that the average cost of a programme was £200 for each" half-hour, and that that period would contain less than three minutes" såles talk ↑

A new class of radio operator's license, to be known as commercial third class and authorizing its hold- ery to operate radiotelegraph or radiotelephone installation on air- eralt and other stations which may he designated by the Federal Radio Commission, has been established by the Radio División of the De- partment of Commerce in Washing ton.

HAVE YOU HEARD THESE?

Here are lists of long-wava and short-wave stations which should be picked up by anyone in Hong Kong who has a mode- rately good set suitable for re- ceiving such signals. Success in picking up there stations also depends very largely upon fav- ourable atmospheric conditions. Readers are invited to add to this list should they succeed in picking up any station not in- cluded in either of those fists.
