PSK31, 63, and all the other digital variants are really fun. Dragging a laptop/tablet around is too much power for me. However, staying at home during an emergency where its easier to have things like a generator or solar array makes it (HF digital) a good tool in the survival/emcomm toolbox.

I forgot to mention that the Elecraft KX3 is a really nice station to put in a BOB. It is a little pricey but all the goods are there. Even PSK. It can connect to software but also of note is the text input via the CW key for PSK, no need for PC.

A note on CW. I've been learning it for about a year now. Nothing consistent in the practice realm but I have and do sporadically. It does take time to learn and I also believe one has to have a desire to do so. It's one of those things that doesn't go into the mind very well. I, personally, just decided to make it apart of my everyday life. I downloaded some iphone apps to practice, regular, free computer software, and when I'm bored, mentally convert text I see to morse. I'm not fast (~10 WPM), but the beauty of it is, the person you QSO with understands that and will slow down.
