I currently own a Radio Shack DX-399 (same model as the Sangean
ATS-606), which is a quite solid, portable LW-MW-SW-FM receiver with
quite good sound quality when delivered to ear buds (FM stereo to
earbuds.)

I mostly use this radio for local MW and FM listening, but will
occasionally listen to SW broadcasts, and DX-MW using a Radio Shack
loop.

I love this radio for its portability, but am looking for another to
put one of them away in a Faraday box for use in case of a major
emergency.

So, what other makes/models should I consider? Repeating some of the
above, here's my criteria:

1) The size of the DX-399 or smaller.

2) General coverage MW-SW (up to 30 kHz), and with stereo FM (when fed
to earbuds). Don't need LW.

3) Good sound quality (especially of FM) when fed to earbuds.

4) As good or better sensitivity than the DX-399 for MW dxing and SW.

5) Don't need SSB, but would be nice.

6) Don't care too much about speaker quality, since I would use it
exclusively with earbuds.

7) Don't care about the other bells and whistles (e.g. alarm), but
some station memory would be nice.

So what are my other options? New and/or used (buyable through eBay)
will be considered.

Thanks!

Roger
