what shortwave frequency for "listening" to Jupiter
I understand Jupiter's sporadic radio emissions can be picked up on the HF
shortwave bands and sound like someone throwing sand grains at a glass window (?). Anyway, what is the general frequency range(s) that I should be monitoring and does it in fact sound like I described? Thanks, John Fox |

Try frequencies above 20 Mhz (the first detection of the decameter
Jovian radio bursts was something like 21.1 Mhz or so). Most seem to like the range of 20 to 24 Mhz, although I have heard of some observations as high as 35 Mhz. The emissions sound a little like ocean waves on a beach. They can be surprisingly loud, but even so, it takes a good shortwave receiver and a directional antenna (and a bit of luck) to hear them. Clear skies to you. -- David W.
