Hi Jake,
Thanks for the ranking and the feedback. I'll try a few variations. Obviously, #58 was meant to represent radio signals reaching out all over Australia, but you're right it's a bit much. :) I was not sure which area to represent. I try a version with the signals radiating in the area of Melbourne/Sydney, another from Perth Area and of course I like to keep the tip of Queensland since it's really identifies as an antenna for the whole of Australia. Please let me know if you rather I use other areas. I'll also try a few different color themes.
Once again, cheers!
