A chanes remark of the Marchese.

THE HIGHEST STATION?

Apparently there is a new re- card to be created-for the highest. station! It is claimed that the highest broadcasting station in the world is the La Paz transmitter, which is situated at a height of over 10,000 feet above sea level. In Europe, the highest broadcast trans-, mitter is found on the Pic du Midi, some 3,000 feet in height.

"At the present time, we are in an experimental stage, but the ex- periments of the short-wave system which my assistants and I are entry- ing out for the Research Organinu tion of the Italian Government and about which 1 may have some. thing to say in a few months time -are altering values rapidly.

Television and the Press,

I asked, says. a Pressman, Mar- chere Marconi how he though tele

vision would affect newspapers.

Whatever happens, I think newspapers will live and flourish," he replied. As life gets more and more rapid, people will need their newspapers, where they can find the news which interests them, rhther than have to sit through watching sheets of news on a screen until they find something they wish to

know."

I then asked the Marchese how wireless in ten years". time would

HAVE YOU HEARD THESE?

Here are lists of long-wAVO and short-wave stations which should be picked up by anyone in Hong Kong who has a mode... rately good set suitable for re- colving such signale. Success in picking up these stations also" depends very largely upon fav. ourable atmospheric conditions. Readers are invited to add to this it should they succeed i picking up any station not in- cluded in either of these lists.
