G.E.’s Trio of Pioneer

Broadcast Stations......... 8

By John Schneider W9FGH

Ninety years ago General Electric

launched WGY-AM Schenectady, New

York, which received only the fortieth

such broadcast license issued. With

a power output of 1,500 watts, the

most powerful station on the air at that

time, the signal was fed into a flat-top

antenna suspended between two 150

foot towers. Reports came in from

listeners as far away as Cuba, England

and Alaska.

GE used its station to develop

new broadcast hardware, including

transmitters and microphones, and

pioneered live radio drama, the first

play receiving 2,000 letters from fans.

By Christmas of that year a special play

brought in 6,000 pieces of mail.

GE went on to build two more

stations, one in Denver and one in

Oakland, California, that it believed

would enable it to cover the entire

country with quality entertainment each

evening. John Schneider explains the

evolution of these stations, which saw

transmitter levels reaching 200 kW, and

how the concept eventually led to the

creation of the NBC Radio Network.

On Our Cover

KOA-AM, Denver’s first transmitter

building between 1934-1940 was located

between 14 th and Krameria Streets on the

east side of Denver. It is a near duplicate of

the KGO-AM building in Oakland, California.

Antennas for VHF/UHF Reception................................ 12

By Bob Grove W8JHD

The latest in his antenna series has Bob Grove W8JHD

looking at various designs for VHF and UHF reception:

ground plane vs beam; wire vs aluminum tubing; horizontal

vs vertical; when and how to use pre-amplifiers, and

proper antenna feeding at the higher frequencies. But

wait, there’s more! Bob also looks at filters, the benefits

of the log periodic dipole array and multi-band dipole clusters.

Mining the Minors for AM DX...................................... 15

By Ken Reitz KS4ZR

In small professional baseball parks in towns

across America young baseball stars struggle to be

born. But, if a star is born will anybody hear about

it? Maybe. Broadcasting the play-by-play in probaseball’s

Triple A league is as much of a struggle as

the game itself. Low-powered, small-time radio stations

do their best to bring a Major League sound to a Minor League game.

How many teams can you hear?

The Ears Have It!......................................................... 17

By Dwight Robinson

From a kid with a new crystal set to a long-time radio monitor with a career

in TV production, Dwight Robinson looks back on a life-long association

with earphones; how they’ve changed and how we changed with them.

FCC vs ICC: How an Indiana Town Changed the way all

Licenses are granted................................................... 18

By Gene Wiggins W9CWG

The FCC issues all radio and television related licenses, everyone knows

that; but this was not always the case. Gene Wiggins W9CWG tells about a

time when the FCC literally went to the mat against the Interstate Commerce

Commission which had a grip on issuing certain licenses relating to a time

when telephone companies still wielded a lot of power.

Signal Hound Spectrum Analyzer/Measuring Receiver.....70

By Bob Grove W8JHD

It’s a spectrum analyzer and a measuring receiver,

but what exactly does it do? Bob explains the functions

and limitations of this device that’s right at home in the

world of software defined radios.

Uniden Bearcat 880 CB Radio

By Larry Van Horn N5FPW

With seven backlit colors to choose from the Uniden Bearcat 880 has a

bodacious display. But, Larry also likes the seven NOAA WeatherRadio channels,

the noise-cancelling microphone, diagnostic meter and clear audio. It’s

a solid performer at $150, but deeply discounted at the usual places.
