This is a recording of the SuperDARN (Super Dual Auroral Network) Radar, or possibly its cousin the TIGER (Tasman International Geospace Environment Radar), as received int he Mojave Desert, California, USA, on April 10, 2011, at 1412 UTC.
The SuperDARN consist of a fairly simple pulsed radar burst that last for several seconds before "hopping" to a new frequency. You can see the bursts hopping around in this video. As several burst overlap in time and a single site can only send a single burst at one time this is an indication that more than one radar is being received in this video, at least two can be seen.
SuperDARN can be found on almost any frequency between 8 adn 22 MHz, but operates on a fairly narrow band at any specific time, the burst to burst hop is not very large, probably on the order of 200 kHz or less.
Very informative on the sounds we hear on SW. I would not have known what that sounds was, thanks for your posting of all the radar sounds etc on your videos, I am learning what some of the strange sounds I hear on the bands are.
