Conelrad! Civil Defense Means Civil Survival!

Siren’s wail! Interceptor planes take to the skies! People scurry to their homemade shelters and barricade themselves inside! Enemy bombers are winging their way over the skies of America! What should we do? Where can we turn?

Why to Conelrad of course.

Conel— who?

It’s a fancy name for communication procedure cooked up by the U.S. government in the early days of the Cold War. The goal? Get word out to every American that the homeland is under attack!

The Conelrad System turned out to be a key feature of my fantastic Emerson 888 Vanguard transistor. A radio that was a homage to the early United States rocket.

Looking closely, you can see two triangles in addition to the numbers on the dial.

The cover of a brochure put out by the federal government to describe the Conelrad program. In case of a tag people would tune in to specific radio frequencies to get official updates and information.
Vintage Civil Defense!

Why etch a couple of pyramids on the tuner of a transistor radio? Were they artistic embellishments, or did they have some other meaning?

The answer to the last question led me to the origins of a program that’s evolved into the Emergency Alert System we have today.

Tune in your AM radio dial to 640 or 1240 for official information
Your source for information

Those triangles highlight two special broadcast bands, 640 and 1240.

A section of the Conelrad brochure that informed people that the system of public emergency broadcasting is the fastest way to get word to the public under attack conditions.
Don’t Panic! They’re Only Enemy Bombers!

They are the heart of the whole Conelrad system. How?

Two paragraphs from the Conelrad brochure. One tells you what radio frequency to tune in in case of attack, and the other says that TV will not work during this emergency.
Conelrad Procedures

When calamity strikes tune your radio to the above-mentioned frequencies. TV or FM are no good here. AM is the way to go!

This page defines the word Conelrad, which stands for control of electromagnetic radiation.
Control of Electromagnetic Radiation

Once you’ve got your AM set powered up you will get your official news and information from the government who has total CONtrol of ELectromagnetic RADiation. Conelrad— get it?

No?

Well, isn’t it obvious? A system set up to communicate with the American public would therefore control electromagnetic radiation— OK. Electromagnetic radiation is a fancy way to say radio waves. A physicist may understand the meaning, but would Joe Q American? A little re-branding was obviously necessary. Therefore say hello to the Emergency Broadcast System later in the 60s.

Here is a list of three different methods of emergency broadcasting. One is a continuous method, or an on-off method, or no broadcast.
Three Different Conelrad Methods

There were three different ways to get the signal.

Which number (640 or 1240) is the right one for your city? This page has the answer. Which ever one works best.
Which Frequency to Use?

With two frequencies available, which one was best? It depended on where you lived.

Sometimes the signal fades on purpose. One station is on the air for only a few seconds, then another takes over. This could cause a weak signal.
Many Stations Broadcast the Same Program, One After Another.

Having one station on the air for only a few seconds, before passing the broadcast onto the next, was a way to trick enemy planes. No signal to lock on? No way to locate your target.

To find out which is the correct frequency in your area you should contact your local civil defense office.
Contact Your Local Civil Defense Office

Contact your local Civil Defense office to find out which official frequency is used in your area. This way you know precisely what to do before those bombers are in the air!

This is the emergency alert message given out. We interrupt our normal program to cooperate insecurity and civil defense measures as requested by the United States government. This is the Conelrad radio alert!
Emergency Alert Message
If no one is listening to a radio or watching television, a siren will sound if an emergency is declared.
A Siren Back-up

Actual Civil Defense sirens still exist in spots across the country. In Los Angeles you can see them sitting on top of poles, swaying in the wind. Until the 1980s their lyrical sounds were heard once a week when the system was tested. They have since been decommissioned.

Not so in other coastal communities, who have active siren systems. Horns no longer blare to warn of impending nuclear annihilation, but have a new purpose. To help people escape a devastating tsunami. Cold War technology still comes in handy.

In an emergency turn to a radio that is powered by a battery. It will still work if there is a black out.
Battery Power is the Best

Remember, you could lose your power at any time. Be sure to have plenty of batteries for your radio!

Don’t Forget your Bomb Shelter!

And don’t forget to keep your handy backyard bomb shelter fully stocked just in case.

Oh drawing of a portable radio from the 1950s, with the frequency 640 highlighted.
A Cool Radio

I hope you enjoyed our visit to the cold war. I’m glad we’ve never actually experienced enemy bombers flying over the continental United States. Still, it’s good to know that cool radios were available to help out in an emergency. Another example of GVS, Glorious Vintage Stuff!
