Several years ago I replaced my L3 Skywatch box with an ADS-B transponder. I still have the Skywatch box and don't know that it's worth anything, but before I toss it, want to ask if anyone wants it. If so, let me know and I'll ship it to you at no charge if you'll reimburse me for the freight. I just hate to toss something that at one time was worth 10 grand or so. If interested, call 912 629 9290.
