Within Alaska, only an inexpensive portable shortwave radio receiver is needed to tune-in and listen to the HF radio transmissions from HAARP. Outside Alaska, a little luck in the form of favorable ionosphere conditions for radio propagation perhaps combined with a more sensitive shortwave radio are needed to receive HAARP broadcasts.
The HAARP transmitter can be tuned to transmit at arbitrary radio frequencies between approximately 2.7 and 10 MHz (i.e. 2700 to 10,000 kHz). This frequency range is between the AM and FM bands received by most consumer radios in home and automobile audio systems. The specific frequency chosen during a particular experiment depend on the experiment objectives, United States Federal Communications Commission (FCC) regulations, and ionosphere conditions at the time.
Most people are familiar with AM/FM radio receivers in home and automobile entertainment systems for listening to local and regional programming. FM radio…
