Hearing Meteors on the Radio

There are always meteors burning up in the Earth's atmosphere, and during certain times of the year there are major meteor showers. You want to watch the meteors but it's cloudy or the moon is too bright or you live in the city with too much light pollution. Even if you can't see the meteors, you can still have fun listening to the meteors.

When a meteor burns up in the Earth's atmosphere, it leaves an ionized trail in the ionosphere, the part of our atmosphere that reflects radio waves. The trails that these meteors leave are ionized and will reflect radio waves off of them. If you happen to be listening to an FM radio during this, you might be able to hear these distant radio stations reflected to your location, sometimes from as far away as 1000 miles.

You can hear meteor pings and long meteor bursts with just about any decent FM radio. A radio with a digital tuner is very helpful so you know exactly what frequency you are listening to. A decent home stereo AM/FM should work fine. Boom box type radios don't usually work very well for this. Car radios actually work great for this. I have gone out to watch meteors and used the car radio many times, watching the meteors and hearing them on the car radio.

If you want to get into this hobby more seriously, there are some radios that are better than others. I have used a factory car radio out of a Chevy Blazer and it has worked great, car radios usually have very good sensitivity and can be found cheap. Many times someone will take out the factory radio and install an aftermarket car stereo. You can find these factory car radios very cheap at garage sales, flea markets and online. You can start with an AM/FM radio or FM stereo you already have, hook it to an outdoor antenna and give it a try.

Radios that are popular with hobbyist are the Denon TU-1500, Sony XDR-F1HD and the Sangean HDT-1. Some will modify the Denon by taking out the factory filters and putting in narrower filters. This helps the selectivity of the radio so you can hear distant stations right next to frequencies that local stations are on.

FM radios that come with RDS can be very helpful when identifying radio stations. RDS will show you a readout of the call letters, slogan, song playing and other information. The above mentioned radios all have RDS.

You can also buy an FM radio that also has AM, shortwave and possibly weather and aircraft bands. This way you can enjoy FM DX'ing along with the other radio bands.

Many of today's new radios only have the extended whip antenna for the FM band and no jack for an external FM antenna. These radios can also work well for hearing meteors on the FM band and other stations during sporadic-E openings.

Using only the external whip antenna on a portable Sony IC-2010 radio, I was able to hear many distant FM stations during meteor showers and sporadic-e openings with the radio on the dining room table.

You can find some great FM receivers on eBay that will work great for FM DXing at low prices.

To hear more meteor pings, a small outdoor directional beam antenna works well. A good small antenna is the FM-6 made by AntennaCraft. Since the FM band starts where the old analog channel 6 is, a VHF TV antenna will work (channels 2 thru 12). Since moving to digital television, you might be able to find an old VHF only TV antenna that someone wants to get rid of.

The antenna doesn't have to be very high; 15 to 20 feet (4.57 to 6.1 meters) above the ground works fine. You can support the antenna with antenna mast from Radio Shack or some other support. Putting it along the house or patio roof works fine. Just make sure you don't put this near any power lines or you could be electrocuted if it should fall. You will also need some coaxial cable to connect the antenna to the radio. This will be 75-ohm cable, which you can also get at Radio Shack or at other electronic stores on the Internet. You can buy the coax with connectors already on at places like Radio Shack, Best Buy or the Internet or coax without the connectors and put your own F connectors on.


You might want the ability to rotate the antenna to different directions. If you have the mast on the ground, you can just turn the mast by hand. If you put it on the roof, you would have to climb up there when you wanted to turn it or buy a rotator, or you could keep it in a good position towards the area where most stations would be.


What You Can Hear

Once everything is up and running, you will want to get familiar with your local FM band. Get a guide that lists all of your local FM stations. You wont be able to use those frequencies. Go across the FM band and record the stations you hear that aren't in your area, you will hear a number of them that are 100 or more miles away. You wont be able to use those frequencies either. Find the clearest frequencies and those are the ones you will want to stay to listen for meteors.

During a meteor shower, listen to the clear frequencies and you will hear very short "pings" that last from a second to a few seconds. Other times you will hear a distant station for over a minute. You will also hear numerous stations at the same time. Radio station signals will bounce off of these ionized meteor trails and that is what you will hear. Sometimes you will hear enough to identify a station. If your FM radio has RDS in it and if the meteor burst is long enough, the RDS readout might identify the station for you. Meteors are more prevalent in the early morning hours, but of course some meteor showers can peak in the middle of the day.

Portable Radios

You can look on eBay for used FM radios like the Sangean, Denon and Sony models listed above or you can get started with portable FM radios. Portable type FM radios are not as good for FM DX’ing as a tuner or car radio because they usually do not have a jack for an external antenna. The only FM antenna they have is the whip antenna, which can do fine in a good sporadic E opening. I have used portable FM radios sitting on my kitchen table with just the whip antenna during a sporadic E opening and listened to stations 1000 miles away.

The Sangean PR-D15 is an upgrade to their PR-D5 model and is a great portable for FM radio (also AM reception). The PR-D15 includes RDS readout and can also recharge batteries while in the radio.


Sporadic E Propagation and FM DX'ing

The hobby of listening to distant FM radio stations is popular and is called FM DX'ing. DX stands for distance. You can listen to distant FM radio stations at times other than meteor showers.

If you invest in an FM antenna and radio, you don't have to use them to listen to only meteors. During the spring and summer months, you can also listen to distant FM stations with a type of propagation that is called sporadic E.

In the northern hemisphere, the sporadic E season usually starts in mid May and can go until September. In the southern hemisphere it occurs around the December 21 solstice. No one knows for sure what causes the ionization of the E layer of the ionosphere, but when this occurs, it can reflect VHF radio signals at distances up to 1,200 miles and sometimes more. There has been speculation that the sun, sunspots or thunderstorms causes sporadic E but none of these theories has proven out.

During a sporadic E opening, the FM dial can be filled up stations and for hours at a time, allowing you to ID many different stations. People in the center of the United States can hear stations from the east and the west coast and also Canada and Mexico during a summer. People living in the Southeastern US can hear into Central America and the Caribbean.

Antenna Accessories

Here are a couple of ideas and tools you can use to get your FM radio antenna up. Antennas for FM DX’ing do not have to be that high off the ground, and 15’ to 20’ above the ground should be fine. If you want to mount it on the roof, a tripod would work with just a short piece of tubing. A rotor would work best for a roof mounted antenna. Winegard makes tripods that work well for this, like the Winegard SW-0010 Tripod Mount.

Whether you mount your FM antenna on the roof using a tripod or on the ground with supports, using tubing like the kind Channel Master sells works great. You can support the mast or tubing along a wall or use the supports of a patio roof, either works just fine.

If you are going to support the FM antenna on the ground using a wall or a post, you will need something to hold the mast in place. There are many types and sizes of brackets that will work. If you mount your antenna on the ground, you can turn it by hand towards the direction you are interested in. A rotor is easier though, but generally during meteors or a sporadic E opening, the direction can stay the same for hours.

      You can see meteor showers from any country. Each meteor shower usually peaks at a certain time, and that time changes each year with each meteor shower. The best thing to do is look between midnight and sunrise your time during any of the major meteor showers and you will see some meteors. The best meteor showers are the Perseids in August and the Geminides in December and once in a while, the Leonids in November. This website lists all of the meteor showers:

      Caribbean people are known all over the world for their music and cricket. The Caribbean islands have produced a lot of legendary singers who have left their mark on world music and can never be forgotten. Bob Marley is the name that occurs to anyone, without fail, when people talk about this type of music. After his sad demise, Ziggy Marley, his son took over the task of producing Reggae from him. Reggae, is a genre that is liked by everyone. this type can be divided into various genres primarily African, European, Indian and native influences. It is a synthesis of all of the above.Caribbean Radio
