22 ------------------
24 I have a RadioTrack card from back when I ran an MS-Windows platform. After
25 converting to Linux, I found Gideon le Grange's command-line software for
26 running the card, and found that it was good! Frans Brinkman made a
27 comfortable X-windows interface, and added a scanning feature. For hack

34 So, without further delay, here are the details.
