This page was created to help those who are interested in the hobby of radio monitoring and want to learn more. In addition to resources in this Wiki, there is also a special forum for beginners on the HF Underground Message Board.

What Can I Hear?

Easy to hear

   (Propagation tip: night time favors lower frequencies, day time favors higher ones)
   (Term tip: 1000 kHz = 1 MHz, so, 14670 kHz = 14.670 MHz)

Time stations - 24/7 broadcast of accurate time:

   WWV WWVH(US) - 2500 kHz, 5000 kHz, 10000 kHz, 15000 kHz, 20000 kHz (WWV only), 25000 kHz (WWV only)
   CHU (Canada) - 3330 kHz, 7850 kHz, 14670 kHz


Where to Listen Online

A quick place to start is to use the links supplied on this page to go directly to an online receiver tuned to the correct frequency. This is only intended to be an aid and not a guaranteed method of hearing any particular station. Remember that not all stations are on the air 24/7 and propagation will effect whether or not you can receive them.


Learning Resources

  • Propagation, Time of Day, and Location

Propagation is the study of how signals can get from the transmitter to the receiver and can vary according to the sun, the Earth's atmosphere, frequency, time of day, and your location. All of this adds to the enjoyment and excitement of radio monitoring. At times a very strong reliable station will become weak and a rare weak station can become strong enough to hear. With practice you can use propagation tools to help you predict the best time to hear a station.
