One of the most expensive single Instruments in the - radio receiving set in the long run is the vacuum tube and at the same time it iti the most fragile For this reason the radio fan should take every pre- caution he can to care for it and prolong its life Several simple precautions can be taken and rules followed in the treatment of the vacuum tube that will permit the best possible results to be obtained from it and at the same time allow the tube to oper- ate for the longest possible time it can The most important part of the vacuum tube is the filament This is the element that throws off the stream of electrons that perform so important a part in any wireless circuit These electrons are thrown off by the filament when it is heat- ed by a current from a suitable battery The electrons themselves are controlled by the 'grid of the tube and the output of the tube is from the plate circuit There is a peculiar factor about the vacuum tube and it is this: The more the current is turned on and the brighter the filament glows the greater will be the number of elec- trons that will be emitted until a certain point is reached—and then no matter how much the brilliancy of the filament is increased there will be no further increase in the flow of the electrons This is known technically as the saturation point and also as the critical point Life Is Shortened The result is that when the fila- ment is burning brighter than what Is known as the "critical point" the life of the tube is being shortened without any corresponding increase in efficiency In fact the efficiency of the tube above this point is of no value whatever and is simply burning up the filament and also current from the battery Some radio fans have devised an arrangement of switches whereby they can connect or disconnect the "A" and "13" batteries at will This is a good idea and is designed for the purpose of reducing the number of adjustments necessary in oper- ating the set Its thief purpose is to throw on the switches and then have the music come in immediate- ly This system however has a very serious drawback as every battery after a rest recuperates slightly an I when placed into circuit again will at first give off more current than at the time it was disconnected It Is best to turn the rheostats back a little before turning on the current Double Pole Switch A suggestion recently made in the "Wireless World" is that the two fil- Lubbock Radio Fan Picks Up Catalina Islands Three more claimants for first honors In lung distance Summer time receiving records have thrown their hats in the radio ring If you think you can beat these or equal them send in your lists of stations heard Here is the record of Paul M Hargis of Lubbock out where the static is bad using a home made single circuit tuner and also a Paragon RA-10 without amplification from Thursday to Friday of last week: KLZ Reynolds Radio Company Denver DN4 Colorado National Guard Station Denver WFAF Western Radio Corporation Denver KUXV Catalina Islands (daytime) W R It Dal la s WBAP The Star-Telegram Fort Worth WRAY Houston MAIL El Paso KSD St Louis Post-Dispatch WDAP Kansas City Star WAAZ Dmporia Kan WAAP Wichita Kan and the station at Shreveport Ea C A Maxwell of Fairfield Texas comes forward with the following list of receiving records using a home made single tube and no amplification: WRII Dallas police department WPA Fort Worth Record WLK Indianapolis WKC Baltimore M W111 Washington D C WHA Madison Wis' WFAA Dallas News WBAP Fort Worth Star-Telegram A third radio fan sent in an imposing list of long distance records from Merkel Texas nut failed to sign his name If the maker of the records will send us another letter telling who he is they will be punlished in the following Sunday issue of the radio page FARMERS SUCCUMB TO RADIO BUG BITE WAXAHACHIE Aug D—Farmers around Waxahachie have succumbed to a new kind of bug—one they are making no effort to kill the new insect is none other than the radio bug A number of Ellis County farmers have installed receiving sets and many others are contemplating setting them up on their farms in order to get the latest market quotations and to listen to the concerts and other features as sent out by the broadcasters from Fort Worth Dallas and other stations Two of the most enthusiastic radio fans are Carl Stiles and C IT Pigg living a few miles south of Waxahachie They both have sets and daily enjoy the broadcasters programs BANDIT IN MONK'S GARB MILAN—Scarselli the notdrious bandit who murders and robs while garbed as a monk has escaped for the fifth time from the Italian police STAR -

INTERFERENCE BY STATIC AND CODE SIGNALS Reduction an delimination of interference from static and code signals by receivers wishing to listen in for a broadcasting station's program is the star to which many experimenters have hitched their wagons in the last few months or so One means of considerable efficiency in eliminating these types of interference is the loop barrage which has proven itsel?for this purpose Radio fans living in the near vicinity to wireless stations or who are bothered excessively by static may find interesting fields for experiment in trying out the loop barrage It can however be used only with a regenerative set and at Least two stages of amplification and use of a loud speaker in connection is out of the question for the loop while barraging out static and code signals also weakens the incoming signals desired to bear to a considerable extent Use of a loop barrage with crystal set or non-regenerative set except in the same city where a broadcaster is located therefore Is futile Three Additions With the loop barrage there are three additions to the regular receiver namely: a change-over switch such as is normally used in direction finding work a variable resistance in the antenna circuit and a loop The loop should be tuned for reeeption on 360 meters which can be accomplished by constructing a loop four feet square composed of two cross arms each six feet long fastened at right angles to each other Around these six turns of No 18 copper wires are wound in such a fashion that each turn is spaced half nn inch from the next turn An adjustable clip is used for tuning in on the loop and this is fastened on wherever signals are at their strongest The change-over switch is used to change direction in which the current flows through the n-imary of the van-coupler This is a very Important point The aerial itself will naturally supply more energy than the loop does and the variable resistance is used for the purpose of striking a balance between the two and thus performs a function that is of the highest importance to the successful working of he entire circuit In this circuit the loop acts exactly as it does when used alone so far as receiving from the direction toward which it is pointed is concerned However when a loon is used alone it will receive equally well from both directions of a straight line When the loop is need with an ordinaxy aerial in the barrage system It will receive only from a forward dirtection Signals coming from behlrfd or from any kupspr by yaattsh ef ooalnleorwt ihasel other direction will

(Copyright 1922 Westinghouse Electric and Manufacturing Company) each other without affecting the detector at all Tuning Barrage Receiver The manner in which the barrage receiver is tuned is as follows: First open the change-over switch entirely leaving the aerial completely out of the circuit Then tune the loop to the desired wave length by moving the clip attachment along one of the wires around the loop until signals are strongest The loop of course should be pointed In the general direction of the broadcasting station which is to be heard As soon as the preliminary tuning with the loop has been completed and maximum signals obtained the change-over switch should be closed down Try it in one position first and if no results are obtained throw it over into another position While doing this the primary of he van-coupler should be adjusted to the 360 meter wave length The aerial tuning condenser which is in parallel with the vario-coupler should also be varieft to obtain best results After maximum signals have been obtained throw the change-over switch into the -opposite connection again and tune until the signals completely disappear then put the switch back into its
