The best European / African station guide that I've found is:

You're right though - it can still be difficult to know what to listen for. Spend some time looking over the frequencies on this guide and first look for the stations in western Europe and Africa with the big powerhouse transmitters as they will probably be the best targets. Here's my list of "best bet" stations you can try for which have been good here at night between about 8pm-11pm EST. I'm sure others will have suggestions too, maybe better suited to your location?
531 Algeria & Spain
549 Algeria
585 Spain
693 UK BBC
747 Netherlands
792 I've been hearing something Arabic here, chanting, maybe Libya
945 France
837 France
1206 France
1215 UK Absolute Radio
1521 Saudi Arabia
1557 France
I suppose the best way to hear these would just be to tune around the dial on your 10 khz setting and start listening for strong beat tones, which would hint at TA signals on the split channels, and then try to zero in on the strongest. These stations fade up and down too so I wouldn't expect to hear audio on the first go - you may have to park it one channel and wait for audio - assuming you found a strong carrier signal to begin with. If you get audio then you can try matching it up with the station's online stream. A good (but not complete) all-in-one source is:

If I were in Florida then I would probably start with some of the big stations from France and Spain.
For people in the midwest, Caribbean ZIZ on 555 has been pounding in at night here too, better than I've ever heard them.
