Fans are anxious, perhaps, to know what interests desire to broad- ast. Most applications appear to come from orzanizations which would put on a good cl: ¢ entertalnment and of public interest. Of the indi- vidual classifications, radio dealers, shops companies lead. with a total of 57 applications; churches and religious organizations come second, with 42: universities, collezes and schools have 35, and electric and ba s or companies ure fourth, having 36 listings Since many gapplic ! without detailed information as to the or industry represented, a complete classification is impossible.

Some of these unclassificd applicants may be planning commer- elal broadcast stations. which are now hecoming Yuite general. For exam- ple, it is asserted that there are only two broadeast stations in New York City which are not broadeasting for profit; in other words, they are prac tically all commercial stations, which, fortunately for the fans, carry good prosrams as indirect advertising fea tures. . Publishers Among Applicants. Continuing with the analysis of ap- plicants, publishing houses and news- papers have applied for 31 licenses in about the same number of localities. Chambers of Commerce in 20 cities seek licenses and 19 organizations and clubs, including several radio clubs, desire broadcast stations.

They be- lieve that such stations, along with thase of religious and collegiate insti tutions, would put on programs mak- ing for better broadcasting. —Two groups—hotels and resorts and auto- mobile and accessory dealers—each ask that 18 stations be licensed their members. Fourteen music and pho- nograph stores are ambitious to broad- cast. There are also 10 banks and financial institutions. Among the smaller groups are eight realtors, <even theatrical enterprises, five lab- oratories and public service organiza- tions and five hospitals.

Don't you know that the matter of selec- tivity is. basically a matter of the resistance properties of your tuning unit: The coil and the condenser?” Smith had been led to believe that if the rotor plates of a variable con denser could be swung through the arc of an elipse by some ingenius eccentric action, the stations would be rspread apart and all would be well.

The small or low power transmitter handling 2,000 watts input to the an- tenna will be used to broadcast on the odd hours, and the big or high power transmitter handling 5,000 watts power input to the antenna will be used on even hours. The switching from low to high power will be accomplished in less than a minute, and no delay in the program is ex- pected. A statement issued by officials of the station pointed out that few low wave length stations, such as WO! which uses the 217.3 meter channel, have had unsatisfactory results with high power because increased power on high frequencies is hard to con- trol. WOK will depend on its listeners for reports as to reception, ‘modula-~ tion, etc. An accurate and detalled check-up will be kept. In order to stimulate interest in the experiment a prize will be allotted to each State in the United States and each prov- ince in Canada. In reporting the re- sults to the station, fans must state the time of tuning, whether the high or low power came in clearest and why they thought so. Tube Rejuvenation Satisfactory. Until a year ago, before the advent of the now plentiful tube rejuvena- tors, the prescribed remedy for & run- down tube was to leave it in the re- ceiver, turn on the filament supply and disconnect the B battery. This proved quite a serviceable cure in many cases, an extra supply of thorium be- ing brought to the filament surface. This was necessarily a slow job. By the use of a rejuvenator, the process can now be considerably quickened, the reason being that a higher volt- age is supplied to the fillament from the rejuvenator than was previous- 1y obtained from the storage battery, when the old method was employed. Most rejuvenators are operated from 110 volts, alternating current, with a suitable stepdown transformer. “Rejuvenators cannot be used with any tubes except those which have thoriated filaments,” writes Keith Henney in the Radio Broadcast Maga- zine. ‘‘They will be of no service with the old tungsten filament 201 or 200 type tubes, or with the new UX-112, or with Western Electric tubes.

From data collected in the Radlo Broadcast laboratory on several types of rejuvenators it was seen that some tubes went dead in the flashing process, while many gave increased plate current. At any rate, the user has everything to gain, nothing to lose, in the process. If his vacuum tube is no good before, it cannot be worse after the rejuvenating process.” WBZ to Aid Balloon Racers. ‘When the three American balloons leave the ground in the international balloon race from Brussels, Belgium, next Sunday afternoon, sceking the upper air currents and distant places, the Yankee pilots and aldes will be in touch not only with the radio broad- casting centers of continental and in- sular Europe, but also with a powerful station in their homeland, 3,000 miles awa; Through the medium of station ‘WBZ, in Springfield, Mass., the Amer- ican contestants for the third time will have the spoken word of encour- agement of their countrymen. The trio of American bags, winners of the national elimination balloon race for 1926 held last month in Lit- tle Rock, Ark., will carry radio instru- ments and confidently expect to tune in the Springfleld station during the air flight, as well as at the outset of the race. In 1924 the signals from WBZ were received while in flight by Ward T. Van Orman, one of the Amer- ican pilots. Reception Bad in California. An electric power voltage line car- rying 60,000 volts has been found to be the major cause of radio com- plaints received in the office of the radio supervisor in California. On a trip through 22 towns and cities in California he ‘found that faulty or dirty insulators, power-line substations and equipment were causing the com- plete blanketing of reception in four small towns. In these localities satis- factory reception of even the more powerful, nearby stations was impos- | sible. Road dust and ether dirt set- tling on insulators was found not as bad during the Winter months when seasonal rains wash the insulators. More serious power-line interference occurs in the Summer months, when dirt accumulates on the insulators and allows the current to leak. ‘With the completion of several new substances under construction most of the troubles will be eliminated, the supervisor believes.
