Just been googling HF and Jupiter. It seems these signals can be picked up between 5 and 40 MHz. Never done it myself, but how hard can it be?

I've been able to receive meteor pings on VHF. The most simple way, if you have a sensitive car radio, is to drive to a hill and pick a frequency on the FM band that has no stations. Make sure you tune to a potential station though using odd frequency channels. Early mornings seem best for this. I often hear Sydney ABC FM pinging in the mornings.
Another thing, though not strictly radio astronomy, is to listen for natural Earth sounds on VLF. You have to be away from powerlines to do it though. One can hear noises from our magnetosphere. Google "Steve McGreevy" for some excellent recordings.
