The mission of Digital Aurora Radio Technologies (DART) is to expand communications across the north by using existing, and exploring new communications technologies. Receiver System
DART maintains a network of receivers located throughout Alaska. The receivers are WinRadio® G-313i units. These units allow rapid measurement of signal to noise ratio, which is then used to adjust transmitter settings. Receive antennas are short dipole configuration, approximately 10 feet in length. The receivers are connected to our network and are under computer control. This means that we can precisely monitor our signal levels around the state, at all times.
Shortwave signals tend to vary quite a bit, with some frequencies working better during the day, and other frequencies are better at night. Sunspot activity can also affect the ionosphere, and therefore, change the effectiveness of the signal. Most shortwave stations stay on the same frequency resulting in signal that fades in the middle of a program. DART, on the other hand, always selects the best frequency to reach the entire state.
You can listen!
We are currently testing DRM on 4.85 MHz, 7.505 MHz and 9.295 MHz. In addition, we are broadcasting CW on 4.851 MHz, 7.511 MHz and 9.301 MHz. If you pick up our signal, let us know - we would like to hear from you.
