Thanks for the welcome and the great advice and counsel, Patrick/Andrew/Christian/Marc/Simon/Siegfried et al.
I did some more poking around on my rig, and found that my audio input to the PC was indeed the Mic input, not Line In, as suggested more than once. Unfortunately, on this PC (a laptop), there is no Line In, only Mike In ... but I think I found a different driver for the on-board audio that will allow me to reconfigure the jack. I will definitely give that a try. If it fails, I have an older / slower desktop machine and a drawer full of decent Soundblaster PCI cards I can try instead. It's a 1GHz P3, but it should probably be strong enough for this. If that fails, I've got a dual CPU 2GHz P4 gathering dust in the corner that's just waiting for a purpose. ;-) I'll also follow up on your other great suggestions, including pointers to other tools/modes and to specific bands/freqs. Cheers and thanks again. - Doug / KE7SEI
