I have mentioned the RTL-SDR previously. Powerful, inexpensive receiving tool. The upconverter extends the coverage down into the shortwave (HF) range.
I know many of you already have an RTL-SDR and computer. Considering it’s hard to find a good SW receiver for $50 unless you get lucky at a hamfest or find one on clearance at Radio Shack, the Upconverter gets you shortwave coverage with your existing RTL-SDR setup at a good price. It’s no R-390, but then again it doesn’t cost $1000 and weigh 70 lbs.
