Scanning through 27MHz & 28MHz (The 10 Meter & 11 Meters Band) USB with The Realistic RadioShack DX394 HF Short Wave Receiver.
The DX394 is a pretty good HF Receiver if your looking for something low cost on a budget that performs fairly well. It has a Coverage of 150kHz -30.000kHz and covers the modes AM, LSB, USB and CW.
I do not know what performance is like but the 394 tunes well below 150khz, al you do is press a couple of buttons & it tunes down to, I believe it is 1hz. There are two models & the B is said to be the better of the two. But I think that is more hopeful thinking than anything else. Yes the B model often sells at a better price, but not always & yes one or two gremlins are sorted on the B model. But most people who do not know what model it is, would be hard pressed to tell them apart in use side by side.
