Got this new all mode, damn near all band, qrp transcever, a new laptop and some Digipan freeware and they want how much for an interface? Not gonna happen! First I tried ginning up the "Dirt Cheap" pot and resistor interface but the salvaged din-6 plug from an old mouse was too banged up so I was looking at spending some money. I had used the mike on the speaker bit for my first SWL taste of PSK when I noticed that the laptop was listening to the speaker, quite well, with its own mike. It slowly sunk thru my thick skull that this laptop was made for video/music types and its speaker, mike and soundcard had pretty good fidelity. So...set the mike near the speaker on the laptop and turn up the volume till the waterfall display looked good, turned on the vox and tried a CQ. KA0UEH replied and helped me clear up some splatter and then Brett, KE5EYQ/QRP/P and I had a 599/599 QSO 5 watts each way-WV to La. FB indeed! Now, on the Brag macro, I call it an "Homebrew Acoustical Interface," real hillbilly engineering-making something from nothing, See ya on the waterfall!
