Online Shortwave Radio Tuner
Ever wanted to listen to shortwave radio but didn't want to cough up $100 for a low-end radio? Well guess what! Now you can with the power of the INTERNET!
Yeah, basically you can scroll down to the frequency and the "waterfall" (as they call it on the page) and tune in. I'm still messing with it so I haven't really found anything all that interesting yet..though I have found "The Buzzer" at 4625.00 kHz USB. You can read more about that on wikipedia if you want.
If I find anything interesting I'll come back and post it here.
