MR. HULL S REFLEX CIRCUIT RECEIVER
In which two tubes are used to function as radio-frequency amplifier, detector, and audio-frequency amplifier, thus doing the work of three
signals were heard at Darwin, 2/00 miles from Sydney. Mr. Dixon was receiving with one valve and standard ship's equipment.
It should be noted that Darwin is 2100 miles overland from Sydney which makes the test all the more remarkable. The power used in this test was very carefully measured and found to be 8.25 watts.
The results of Mr. Maclurcan's latest tests have just been received by telegraph, and state
that Mr. Hull at Melbourne (450 miles away) heard Mr. Maclurcan transmitting specially arranged code signals at noon yesterday, September loth. Only one transmitting bulb was used and the input power 3.8 watts.
From the foregoing remarks, we might feel justified in thinking we can peep into the future and see ourselves talking to friends in distant lands with no more trouble than pushing a button.
If You are Thinking
Of submitting an article to RADIO BROADCAST, you may save yourself and the editors time and trouble by considering the following notes as to what we want:
WE WANT: True accounts of the uses of radio in remote-regions.
Short, true stories of adventures in which radio played an important part: unusual and interesting occurrences to you or your acquaintances.
Clear explanations of new or especially effective circuits or uses for apparatus.
Concise and logical discussion of some important problem or phase of radio, whether in the field of broadcasting, constructing, operating, buying or selling; or of reading or writing that has to do with radio.
True accounts, of some particular interest, relating "What Radio Has Done For Me."
Humor, when the object is not merely to appear funny, but to present some phase of radio in an attractive, amusing way. The same applies to drawings.
Clear, unusual photographs are always in order, as are good circuit diagrams.
A liberal rate is paid for material used.
