If you use your PC for radio control, then you owe it to yourself to check out Ham Radio Deluxe. It supports a large number of radios and Simon and Pete have recently added ILG SWL database support and it is nothing short of fabulous. The support is better than you can imagine. If this isn't enough, then consider that Ham Radio Deluxe is completely free.
