does pretty well for an old receiver.. I like the antenna tuning feature... Seems fairly sensitive and I've heard radio New Zealand here on the East Coast us.

Good sturdy portable, its very capable.

Surprisingly good SSB reception and sound. Its better than the more well known DX-440 in this regard. The DX-400 was only on the market on for a year and-a-half or so before being replaced by the DX-440. This is the superior radio, I've owned both, however it does not have a tuning knob. Keypad only tuning.
