LONG-DISTANCE TALKING

■ ■■- •■ a«r» — ■ FROM MOSCOW TO LONDON.

Through a bedroom window in Loni don recently there came rapid automatic wireless telephone messages that were being sent out by a Bolshevik operating in Moscow.. A Daily Chronicle representative, who listened to these communications, heard also messages from Hanover and Carnarvon. They were all received, on a new and specially designed, n.achine set, which Mr Powell ilees (brother of Sir J. I). Rees, M.P.), has invented. It has been named the 'H.P.R. Long Range Receiving Set," and its manufacture for amateurs is shortly to be begun in the Old Country. The remarkable feature of this set is that it is,all contained in a -tiny box, and is* said to be so simple in ite mechanism that a child ca\i work it. Its range _of capacity can be easily increased without making it clumsy. The cost of manufacture is only a few pounds. With three thermionic valves, which >nay be described in non-technical terms as "magnifiers," messages sent from a distance of thousands of miles can be heard with great distinctness. Every Sunday between 3 and b' and 6 and 8 p.m. Mr Rees listens to a telephonic concent in Italy, and telephonic conversations from 'ether stations are regularly heard. The American stations are plainly readable on this tiny set although the aerial used is only a wire 85 feet long hung between tho upper bedroom window and a tree at the bottom ot the garden. Mr Rees has spent some years in experimenting in wire-k-fis and is a member of the Wireless Society. Included in his patented achievements are his system tor reducing the spa.?e occupied by the appaiatus for long wave lengths.
