Among the many interesting news items of the week is the announcement of the forthcoming experiments ot tne eadi: lentists 0! e a e watns wich are supposed to originate pn the planet Mars. These experiments mean nothing to ithe folks on the earth, and {f there is life of highly organized mentality on the ‘other planets, what of it? In the event the signals emanating from their sup- posed source, who is going to interpret them and how will we know what they mean even if we can fog out a meaning Fall our own) from the vibrations re- eived? Wireless is just beginning to open its 3 on this little sphere of our own, nd although much has been done with e elusive wave there is still room for provement—as any operator who has fried to work through static will testify. is a shame that scientists who know p much and who could probably make ‘dio nearly perfect if they tried should ve their heads so far above the clouds to be out of touch with all things joridly in an effort to attain something at if they are successful will mean {ttle more than nothing to them and s to humanity in general. HeInstoad of spending their lives trying interpret messages from the stars let pem get busy on the more practical jde of radio and give us a little eff ency in transmission and devise some- hing to eliminate static and turn their ttention to fecting a selective sys- ym so that radio will become the most ractical method of communication. ‘hese things will mean something to us nortals and be worthy of the efforts of r leading scientists.

They have worked many stations within a radius of 200 miles and have listened to a Chicago-amateur through the local interference. The receiver used was a standard short wave re- generative set with three stages of am- plification with a power amplifier. ( auestions AND ANSWERS Nnsisantimanetiniensnceneimencatastinnts Albert Spear, Lake Mahopac—'Will a solid wood cylinder three and one-half inches in diameter and nine inches long be a suitable form on which to wind the wire for a two-slide tuning coll, ur would stout cardboard be better? How much wire will I need to wind this cot! and what is the best kind to get? Can I take the lead in from the aerial to the instruments from any other place except the end withoue impairing the receptive quality of the aertal? Are two crystals better than a crystal and eatwhisker for tuning purposes? I want to install a vacuum tube set, but want to learn something about radio before I spend any money." Ans.—The wood cylinder will be just as good as any cardboard form that you can get for a two-slide tuning coil. You will have to buy one- half pound of No. 22 single silk or cot- ton covered copper wire or the same amount of No, 22 enameled copper wire. ‘The lead in may be taken from any con- venient place on the aerial without making any noticeable differency to your reception. You will find that the crystal and catwhisker will give better adjustment than the two crystals, ‘The idea of starting with a crystal set is good, but I am afraid that you are too far removed from the centres of broad- casting to receive anything on a crystal set. The crystal is not sensitive enough to detect the signals from such a great distance, while the vacuum tube can be relied upon for this purpose. Gordon MacIntyre, City.—"'Can I use a number 14 aluminum wire 150 feet long for an aerial in place of the usual copper wire?” Answer.—Yes, the alum- inum wire can be used but it {s not as durable and strong as the Copper wire and will corrode much quicker where- ever an outside connection is exposed to the weather. It is much weaker than the other wires and will not stand very much of the winter wear and tear. Copper weld wire is almost as cheap and will give infinitely better results. Donald Muller, Scranton.—‘Will 1 circle of sheet copper mounted behind the variometer vario-coupler and other knobs on the panel of the receiving set eliminate self capacity effects?" Answer. —If they are grounded they may help, but why go to the trouble of mounting the separate circular pieces when it will be much simpler to remove the panel board and past a sheet of copper foil or thin sheet copper on the back of it which will give you practical immunity from self capacity interference. It will be just as cheap and the results ob- tained are far better than the many in- dividual shields. The mounting should be carefully done so as to give all bind- ing posts and wires that pass through the panel board a sufficient amount of clearance so that they will not touch the copper shielding, which would other- wise short circuit the whole instrument The sheeting should be grounded at the ground binding post Perplexed—‘‘Last winter I purchased an R. C, set and have had good, clear reception with it up until about three weeks ago. Since then I have been get- ting a lot of unaccountable noises that drown out all reception. I have been all over the hookup and there is not 2 loose connection in it. Do You think it is the fault of the tubes or the bat- terfes?"” Answer—You are just getting a little of the effect of static which w have been telling so much about latel: This interference will increase until th cold weather .sets in again. The bat- terles and tubes are not at fault. It is OOO NOVO Radio Items At Special Prices The Qualitone makes radio audible to a roomful of people.
