I too slowly learning more about Radio astronomy but in my situation I am a qualified Radio tech in industrial radio. I am not a HAM radio operator.
Radio Scatter is the best way to listen and from some site I have read the best freq to listen to scatter is 50 to 52 MHz on SSB or CW. This was a quick read.
The main reason is quiet zone, anything under 20MHz is subject to major atmospheric noises and other transmissions from HAM and commercial operators. Those frequescies are heavily subjected to solar noise. I used to work Northwest a lot in remote sites and we had special charts to determin SSB frequencies needed to use due to sunspot activity. Low MHz freqs are used for long distance as signal bounce off the atmosphere to obtain distance.
The only other way to listen to meteors is via Doppler shift which requires you to transmit a signal. I believe the US marine uses 40MHz although to do that in Australia could be frought with interference laws. You would need a licence and you may not be able to transmit on astronomical freqs.
I am doing some quiet studies on RA and hope to purchace a WinRadio setup as well.
I intend to purchace the high end version going right up to 3.5GHz
