1 IN THE WORLD OF RAP IQ 0 Radio Range Will Develop 10-Fold .Manufacturers Predict Revo lution in Industry Within Five Years. Cleveland, O., Nov. 21.—Tha range of radio aets will be Increased tenfold. Interference will be drowned out and static eliminated by high power broad casting, Just getting tinder way. Tow el Crosley, jr., Cincinnati, head of the Crosley Hadlo corporation, de flared in an address before the Elec trical Supply Jobbers' association here. Gen. Guy E. Tripp, chairman of the AVestinghou.se Electric and Manu facturing company, another speaker, declared that the radio industry has grown faster than the automobile in dustry and has not yet reached the saturation point. Eight per cent of t'ha Westinghouse output Is radio »qu!pment, Tripp aald. The radio Industry is In a chaotic state because everything that has the name radio will sell, Crosley declared. The business will settle down to healthy competition when big manu facturers are able to meet the de mand and then "the public will be more discriminating."’ "Dealer* should build a sound foundation for this tremendous In dustry. which looks big today, but is only a dwarf compared to what it will be within five years," Crosley said. "Broadcasting is the foundation of the Industry. Most people take it ns a matter of course, but without It there would he no Industry. You will see a gradual decrease In the num ber of .small broadcasting stations. The tendency Is for more power. The 500-watt station of today will be a joke a few years from now." Tripp warned the dealers that they must prepare for the time when the big power and lighting companies start to sell electrical goods. Admitting that the cost of dlstrth tiling products Is a cause of much of the economic unrest, he said, he did not know now to reduce the number t»f middle men or to reduce the cost •xcept by increasing the turnover. -- " \ RADIO v -—----—-J Rrufrani i«»r Nov.

Attention these generally overlooked it< ms will lesult increased “D\" and put apparatus in best working order.- ------>j S' By FREDERIC BORTZMEYER. With the arrival of fall the radio season proper reopens for the winter. Those of ua who put away th# set entirely for th# summer will now son be reinstalling It; and these of its who built a portable receiver for the past months will be storing It away and turning to our old winter standby. At all events many radio fans will be resuming their pastime of listen ing-in. Some will have their expecta tions as regards the performance of their old set entirely justified, but how- many will be disappointed and puzzled at their set's failure to func tion with ail Its old vim and punch? It may seem absurd that a. set will lose its efficiency In a few months of disuse, but that such In th# case oftentimes has been proved In the pat. This article Is written In the hope that much trouble and expense on the part of the radio fan and the junking of a god set which needs only overhauling and cleaning may be done away with. Ordinary Dusting Not Enough. It is not s'iffi"i/£nt to wipe all the visible dust from the interior of the set. Every instrument composing it should be thoroughly cleaned. Several small, soft, rtenn rotton cloths and n piece of stiff wire will he sufficient for dusting the set. Do not over look the Inductance roll, for dust lodged between turn* of wire will as sist in making the set a broad tuner and, because of the greater dls j tributed capacity, will also cause r* duced signal strength. Dust furnishes shorts and by passes for radio fre quency currents. All wiring should he gon* over In case some unknown accident may have happened to the »et while it was In disuse. It may have been sub jected to some mechanical ahock about which you know nothing, and If the wiring haa been Injured you may burn out a tulie or two as a consequence of a short circuit. If the set has been stored In too warm a place, any surplus soldering paste which may have been left under a terminal or a lug will have melted and imsslbly caused corrosion. Again, you may have been In somewhat of a hurry to try out your new portable when you stored the old set last spring, and may have accidentally Injured some of the wiring. As mentioned before, all of th# In dividual Instrument* composing th" set should be Inspected. Dust col lected on the plates of variable eon denser* greatly alters their r.apacl tare* value* and consequently their efficiency In the circuit for which thev were intended Pigtail connec tion* to moving parts may need to be resoldered to the shafts before they are capable of being put to hard service alt winter Contact springe of tube sockets should he removed from the sockets *nd filed until they present a shining surface. This in sines against a high resistance layer of corroded metal being present be tween the prong of the tube and the metal proper of the contact spring. Good contact at this point la espe cially Important In the grid circuit. Renovating Jacks. Telephone Jacks should have the assembly screws tightened, because temperature changes and tension and stress of wiring may have forced them loose. Good contact between th# spring arms may he had by drawing a piece of very fine sand paper through the arms, a* shown in Fig. 1. The paper should be drawn through twice only, nhre with the abrasive side tward one arm, and Once with it toward the other. Do not draw the paper through repeat edlv. The contact ffoints on the spring arms are usually of silver, a comparatively soft metal, and these must not be worn flat. If your set has the panel complete ly shielded, each Instrument should he individually tested for short* to the shield and ground. If it has not heretofore been shielded and you wish to provide against body capar ity, the following steps must be taken: ^ Remove all Instruments from the back of .the panel, and with shellac apply a sheet of metal foil over the entire panel. From the front of the panel puncture the shielding through the shaft holes and mounting holes. Turning to the back of the panel again, scrape away the foil frorrt each of the holes, leavii^? a space about the size of a dime unshielded around each hole as shown in Figure 2. Now the instruments may be remounted.' all being hob! clear from the shield by fiher washers over the shafts and ^ mounting screws, as illustrated by the side view in Figure With the shield grounded, the set wdl be freed from many extraneous noises aryl from body capacity. Some vacuum tubes refuse to os cillate when new or after a long pe-1 riod of inactivity. This trouble some.' timec can be remedied by placing the! tube In the circuit and allowing It to remain lighted for some time. A1 though "R" batteries have great re cuperative strength, they will not per form efficiently after a long period "on the shelf." It must be remem bered that the plate circuit voltage must he kept above a certain poten tial, below which the tube will not function at *11. Thus your battery may not be dead, but may produce a potential below' the operating point of your tube. < ’ompresslon type rheostats should bo taken down and cleaned and all metallic contact points inside the in strument polished with emery cloth. Several of thesepoint a are shown In Figure 4. In front of the panel we will not find much to offer serious trouble. The s|>ace between sw'itch points should be kept clear of dust snd grease. Panel mounted grid leaks should be readjusted snd fitmlv fas tened to the panel. Warped dials will not provide a reason for a set s fail ure to function, hut the yare \ery annoying and cause dial readings to be inaccurate. if you have not used your arelal all summer and have allowed It to hang grounded. It would he a safe plan to follow to lower the aerial and Inspect the Insulators. Joints and guys. If the wire he badly corroded. It would be best to replace It with new. Cracked insulators should likewise be replaced. All the intac Insulators should he washed clean of dust and smoke particles. Cut the aerial wire from the Insulator Just before the point at which It Is connected to the latter and then reconnect It at the new end formed, as shown In Fig. 6. This provides against the aerial wire breaking at this point because of the softened condition of the wire, caused by Its being bent backward and for ward so frequently. Inspect the soldered Joints and see If the guys hold the aerial stationary. Turn buckles (Fig. 61 placed in the guys assist in keeping the aerial under proper and constant tension. From the foregoing It is easy to see the great number of places In which trouble may he found and remedied In a eet which has been “carefully” stored for the summer. An automo bile which has been in storage for some time must he thoroughly over hauled and returned befrre it will op erate with Its old efficiency. If this he the case, how much more careful ly must we prepare a radio set In which the Initial electrical energy fur nished us with which to work Is ao small! In storirfg your set next spring think of a few of the diffi cultles with which you met this fall and guard against their recurrence. “B” BATTERIES NEED WATCHING Tf there nr* undue noise* in your set for which you cannot account, it would be highly advisable to inspect carefully the terminal connections on your "It" batteries and also any connections between *‘B" batteries, ns corrosion at this point will cause no end of trouble In your reception.
