Frogs & Communication

Acoustic communication is essential for the frog's survival in both territorial defense and in localization and attraction of mates. Sounds from frogs travel through the air, through water, and through the substrate. The neural basis of communication and audition gives insights into the science of sound applied to human communication.

Amateur Radio Information

Do you want to know something about Ham Radio? How do you get started in Ham Radio? You came to the right place. Take a look at what the American Radio Relay League has to show you!

Earth Imaging

A great graphical view of the Earth with the Sun line displayed. Great for checking the "Grey" line. This is a beautiful display and there is even some user configuration that make it more useful.  Be sure to take a look. That however is only part of this site. Whatever you do, look around at the rest of the site too. John Walker has put together one of the most interesting sites on the web and it is a real experience. Make sure you stop at the Titanium Cranium pages.

Federal Communications Commission(FCC)

Yes, that FCC! Good information about the Federal agency that administers all of the radio services including amateur radio. Just revised recently. Much nicer site. Faster too.


qrz.com is one of the most popular ham radio oriented sites on the web. It has a great callsign lookup, forums, and a place to sell or buy used radio equipment. Lots of things to look in on.

Radio Amateur Satellite Corp. (AMSAT)

This is the organization that brings satellite communications to the amateur community. In conjunction with similar organizations around the world, they engineer and build the satellites that have provided so much excitement in the amateur universe.

Strong Signals

If you are a real scanner person, you'll love this site. Reports and rumors, News and views about the world of scanners.

Earthquake Information

This site has a map of California with almost live indications of earthquake activity. How many do you think there were last week and maybe even yesterday? Then take a look around the rest of the site for more information.

Heavens Above

A very interesting site for for satellites and astronomy. You are able, for an example, to identify your location and get a list of all satellite passes for the next 24 hours. Lots more.

Hubble Space Telescope

This is one of the most exciting sites I have ever found. Not only does it have some of the greatest pictures of our solar system and of deep space, but make sure you look at the real time position of Hubble at http://liftoff.msfc.nasa.gov/realtime/jtrack/3d/  This is one of the more amazing web displays I have ever seen. Try everything that is listed on the main page. Truly a wonderful piece of programming.
Skymap Software

Astronomy software for sale, news, several databases of astronomical objects and an opportunity to join in on discussion of astronomy via a listserv.

Star Gazer

Jack Horkheimer is nationally syndicated on PBS and distributed on USIA Worldnet amoung others. A very nice popular look at Naked Eye astronomy.

The Weather Channel

Brought to you by the folks at The Weather Channel on cable TV. A VERY well executed site with a lot of information for anyone the least bit interested in the weather. Aren't ham radio operators interested in the weather, like wind and ice storms?

Lightning Storm Display Map

I'm sure you have seen this on the 10:00 news and weather, now see it on your own computer. This is a grid map showing lightning across the US.


This Noaa site will provide you with information about where there are National Weather warnings. Refreshed for all catagories every 60 seconds.

Space Weather

Weather in space? Well, you better take a look because it directly affects Ham Radio communications. Solar flares zap a science satellite. A coronal mass ejection sparks a stunning display of aurora borealis. Blazing meteors streak through Earth's atmosphere. All these are examples of space weather.

Aurora Information

The process to estimate the hemispheric power, and the level of auroral activity, involves using this normalization factor which takes into account how effective the satellite was in sampling the aurora during its transit over the polar region.

Amateur radio, often called "ham radio", is both a hobby and a service in which participants, called "hams," use various types of radio communications equipment to communicate with other radio amateurs for public service, recreation and self-training.

Amateur radio operators enjoy personal (and often worldwide) wireless communications with each other and are able to support their communities with emergency and disaster communications if necessary, while increasing their personal knowledge of electronics and radio theory. An estimated six million people throughout the world are regularly involved with amateur radio.

The term "amateur" reflects the principle that Amateur Radio and its skilled operators are committed to helping communities without financial compensation; whereas Commercial Radio operates purely for profit.
