America's First Radio Tour

The year 1922 was the year of America's First Radio Tour. In June the Detroit Board of Commerce, the Detroit Automobile Club and the Lincoln Highway Association sponsored a traveling radio event. Two cars were supplied by the Rickenbacker Motor Company. The Tour left Detroit on June 1, 1922 and arrived in Los Angeles July 13th, 43 days later. More here. But this was no broadcasting bonanza, it was a listening tour. On July 10th in San Francisco Mrs Blood was quoted:
"Every night we would tune in, no matter where we were along the Lincoln Highway. One night, when we were nearing Omaha, we listened to Eddie Cantor and Fanny Brice, who are with the Follies in New York. We had a vaudeville star for an entertainer nearly every evening."
The two men in charge were Wallace Blood and O. William Heinz, both Detroit business men and radio aficionados. They were accompanied by their wives. They were showcasing new radio equipped cars following scheduled concerts along their route. William Blood was (probably) the ad man, a partner at Campbell, Blood & Trump. It was a promotional tour.. plain and simple. But in 1922 reception was not a given. In parts of Nebraska and Ely, NV they couldn't receive anything either due to conditions.

The lead car was outfitted with an exceptionally sensitive seven-tube radio receiver built by Tesla Labs. It came with two powerful antennas and a Magnavox "Magnaloud" speaker. The first antenna was a 200 foot loop on the roof, and the second (a back up antenna) was just a 200-foot aerial mounted on the running board. The second was also a supply car to carry stocked with replacement parts to keep the radio working. More here.

Contemporary articles claim they drove 2,800 miles. But even in 1922 that drive wouldn't take 43 days. That's only 65 miles per day. On the other side of Carson City is Lake Tahoe. I suspect they made a lengthy stop there. Route 80 didn't exist yet so it's probable that they took the Lincoln Highway as per their sponsors. But clearly they took breaks, stopped often and didn't exactly hurry. While in Nevada alone they stopped in Ely, Eureka, Austin, and Carson City.

First Broadcast from a Train (Part 2)

Back in 2009 I posted a claim that the first broadcast from a moving train was staged in 1932. That post is here. A commenter rightly pointed out that trains did have wireless communication for decades before that. So allow me to walk back my post, and explain why I went with the 1932 date. Factually speaking, the Lackawanna Limited train tests of 1913 and 1914 were transmitted from a moving train. So I'll concede that point. Certainly any radio man with the right gear could have listened in.  But I'll split hairs on one point: This was not a broadcast per se, there was no program of entertainment; these were all intended to be person-to-person transmissions.

The Lackawanna Limited train left New York City on November 21st, 1913. It was the first train in the world equipped with wireless telegraph. Tests were conducted that day and on several later occasions, probably at 1600 meters. On the same Lackawanna train on May 1st, 1914, similar tests were conducted by De Forest radio telephone.

On April 5th, Lackawanna conducted its a public radio phone test on a train called the Cornell Special, that ran between Ithaca, NY and New York, NY. It departed at 12:35 PM and arrived in NYC at 7:10 PM. What was public" about this test was that they had installed speakers in the buffet car, so that passengers could listen to concerts broadcast by the various radio transmitting stations. It was an unheard of luxury at the time. They also had a small transmitting set on board for the purpose of testing the transmission of messages to and from the moving train to amateur radio stations along the route. I'll quote at length from Railway Signaling And Communications, of April 1922:
"The set used was operated by two young radio experts, David W. Richardson of Princeton University, and G. Donald Murray, both of whom were in charge of radio station 3DH of Princeton University. The Lackawanna installed wireless telegraph service at Hoboken, N. J., Scranton, PA, and Binghamton, NY, during the fall and winter of 1913. The installations consisted of standard Marconi apparatus. Five kw. was used at Hoboken and 2 kw. at Scranton and Binghamton, using multiple plate quenched gap and the induced voltage was 20,000 at 500 cycles; wave length 1,600 meters. No difficulty was experienced in maintaining continuous communication and a large amount of traffic was handled. Early in 1914 telegraph sets were installed on the Lackawanna Limited. Motor generators were especially built by the Crocker Wheeler Company, to operate on the 30-volt car lighting service."
The antennae were removed at the beginning of WWI, though it was later re-installed. Wireless radio signaling quickly became indispensable there and everywhere.

The first stations in each state

I didn't do the research on this, but I did check their list twice. And rearranged it into chronological order. It's a list of the first licensed radio stationin each state. Well all know KDKA, and WQAM, and WBZ but the rest are surprises. Also surprising is how long some states took to get it together. It's very interesting, and the rest of the National Radio Club website is also well worth the browsing.http://www.nrcdxas.org/
