RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

This particular article from a 1940 issue of Radio News magazine touches on two of my hobbies - airplanes and Amateur radio. Whereas most of my flying experience is with all forms of models, here is a group of Hams who provided logistical radio communications during the 3rd Open American Soaring Contest, held in Lockport, Illinois. W9USB was the call sign granted by the FCC especially for the event. Such a contest requires administration and coordination of air and ground aircraft movement, tow winch operation, pilot status, event scheduling, and emergency services if required (fortunately, none were). Being an all volunteer effort, the "Prairie Dogs" subdivision of the "Hamfesters Club" of Chicago. As pointed out in the article, the highly successful operation was a great public service demonstrating the capability and utility of Amateur radio. Many major Ham equipment manufacturers donated items for the contest.

Managing Editor, Radio News, and Chief of Communications, 3rd Open American Soaring Contest

Assembling what has been termed the greatest amount of equipment ever used for so short a time, and certainly the greatest communication network ever to be used in connection with a Glider Meet, W9USB went on the air for the ten days starting August 24, through September 2, at Lewis School of Aeronautics, Lockport Airport, Lockport, Illinois.

The main station, which was given the name of Radio Central for easy identification, was located in one of the class rooms fronting on the airport. On a "U" shaped series of tables were placed 5 transmitters, 9 receivers, 2 P.A. units and a interconnecting board. The units were in use for an average of 10 hours per day on all phone frequencies from 160 meters down to 112 megacycles.

In Radio Central were 2 Hallicrafter's 100-watt . transmitters, one 450·,watt Hallicrafter's transmitter, one 56 mc. W9ETI unit, and one 112 mc. Abbott "souped-up" unit. In the receiving department, the RCA AR77 stood watch on 160 meters. Hammarlund HQ120X on 75 meter phone and 3105 kc. itinerant a.ircraft patrol, an RME 69 on the broadcast band, and special Howard 437 on 275 kc. for aircraft weather, a Hallicrafter's 5-10 on 28 mc. phone, the W9ETI unit on 56 mc. phone, the Abbott on 112 mc. phone, the National HRO on 14 mc. phone, and the Hallicrafter's SX25 on reserve, all band duty.

On the field were two and sometimes three "Prairie Dog Specials," home built affairs, on 160 meter phone transmitting and receiving. The "Prairie Dogs" are a subdivision of the "Hamfesters Club" of Chicago, engaged in A.E. C. work. Also there was W9PSP with a 28 mc. portable transmitter and receiver, W9ETI with a 56 mc. transmitter mobile and a 20-160 meter Howard built into his car as a receiver. W9QEA had his car as an Emergency Mobile with a duplication of W9ETI's equipment plus an RCA AVR-15 aircraft receiver for immediate weather and beam reports from Chicago Airport on the Lockport Field. In addition to this, there were never less than four and sometimes as many as six 112 mc. transceivers and one or two 56 mc. transmitters and receivers on the field occupied in one duty or another.

It was the work of W9USB, whose call-letters were specially granted by the Federal Communications Commission, to coordinate the various phases of the meet. In this capacity all manner of traffic was handled over the station, from a Disaster Flight, similar to that one done in the East by W2USA, to finding mothers and fathers for lost children.

Although it rained sufficiently for four days to turn the Airport into a sea of mud in which more than one radio car got stuck, over fifty amateurs turned out over the air and in person to make the radio end of the meet a huge and gratifying success. Most active in participation was the Hamfester's Radio Club of Chicago, whose members were rounded up by Warren H. Keller, W9RRC.

It is Warren's picture that graces our cover this month. Not only is he fond of radio (he's a licensed ham), but he bore such a striking resemblance to President Roosevelt in a characteristic pose, that we thought it too good to pass up. Incidentally, Warren has worked in President Roosevelt's old law office, and is many times mistaken for the Chief Executive whenever he is in Washington where his work as a Certified Public Accountant occasionally takes him. W9RRC is 41, a native of Chicago, and - believe it or not - that's his own cigarette holder (which Warren says he was using long before FDR's became so famous) and his own hat. Warren states that he doesn't mind being the President's double, except that some times it annoys him to have people stare at him ... and another thing, he's a Republican. At the Glider Meet everybody affectionately called him "Frank."

In the Disaster Flight, W9USB was the key station assigned to clearing planes from the "outside" into Lockport which was the scene of the "simulated disaster." Planes came in from as far away as 300 miles, having first cleared through local hams with Radio Central. They were then instructed to land at Joliet, Illinois, where through W9REA they were routed, one group at a time. to Lockport, with their precious bundles of "simulated drugs, simulated blankets, and simulated nurses." Enough credit cannot be given to W9IMB in Chicago who spent many hours standing watch on the frequency of W9USB, keeping it clear, and rounding up hams in the outlying districts. These hams obtained the names of the pilots, and the numbers of their respective ships, and forwarded that information to Mr. Lawrence Lawver. Executive Assistant of the Airplane Owners & Pilots Ass'n., sponsors of the Disaster Flight, via W9IMB-W9REA-W9USB.

Special QSL cards were printed for the occasion and they were distributed to all hamops who were contacted. An interesting sidelight on the QSL's is that they were "glider flown." We believe that this is the first time that any ham QSL's have so been treated. Each QSL bore the imprint of the Lockport Dedication Stamp, which will make them rare keepsakes. Special Certificates of Meritorious Service were also presented to those radio operators who were instrumental in making W9USB a success. These are personally signed by the Most Reverend Bernard J. Sheil, Senior Auxiliary Bishop of the Archdiocese of Chicago who for the Catholic Youth Organization was one of the sponsors of the Meet.

While the work was gruelingly hard at times, and specially at the time of the Disaster Flight when five transmitters and seven receivers were going at one time at Radio Central, there were pleasant moments for all ops. Almost everybody had a chance to fly, and some made their first "hops" at this Meet. Ollie W9ETI Read distinguished himself by being one of the few hams who has ever had a glider flight. On several occasions Ollie took up a 112 mc. transceiver with him and spoke to W9USB from heights of over 6,000 feet. His conversations were heard in Chicago, over 38 miles away. Through the interconnecting board his conversations with W9QEA at the mike of W9USB were put on the field's P.A. System and the crowd that attended were treated both ends of the QSO. Incidentally. it was possible to put any receiver on the P.A. System and the glider pilots made use of. this in getting their weather reports, as well as orders which might have been originating anywhere's out in the mile-square airport. Contacts through the loud-speaker system and the "Prairie Dog Specials" was excellently done, and handy in emergencies. Even 112 mc. was pushed through the P.A. System; and on one occasion W9QEA spoke to W9ETI via a route that went like this: W9QEA (on 112 mc.) to W9USB, W9USB to W9ETI via the P.A. System. W9ETI to W9USB via 56 mc., W9USB to W9JU via the P.A. System. W9JU to W9QEA via 160 Meters. Some of the hookups were "complex to the extreme, all as the occasion might dictate.

Co., Camden, N.J.; Radio Mfg. Engineers, Peoria, Ill.; Radio News Magazine, Chicago, Shure Brothers, Chicago, and Triplett Electrical Instrument Co., Bluffton. Ohio.

From the reports trickling back to us, the pilots of the gliders as well as those who put on the Meet, were pleased beyond words with the operation of ham radio. We believe that the presentation which was given to the public at the Meet, of what ham radio can do, was excellent publicity, and did much to raise the esteem in which the public holds the ham.
