CW /certainly/ isn't obsolete!

CW is quite obsolete in the commercial radio world. However I agree CW
still can be fun to use in the ham radio hobby.

I can make QSOs with just a few Watts...

I would agree that CW works better than most other modes under adverse
conditions. That's one of the reasons I've been using it for so many
years. My HOA required stealth antenna is a very poor radiator, and
even though I'm running 50 watts, my ERP is probably just a couple of
watts...
