I've been quite happy with the portable Eton G3 World Traveller Radio.

With Digitally tuned AM/LW/FM-stereo, the complete Shortwave
spectrum with SSB (150-30000 KHz) and the VHF Aircraft band (118-137 MHz) it is quite a good sensitive tuning performer.

It also has an inbuilt AA charger so will charge the 4 AA cells from an external 8V power supply so doesn't need an external battery charger. It also has Line In/Out so can even be connected directly to a solar powered Hi-Fi Amp and Speaker.
