Pretty neat article. I was thinking the other day how many “low tech” devices that have fallen out of use could find a role today.
Now, I admit I was thinking in terms of various “bug out”/SHTF scenarios at the time, so I was thinking more along the lines of carrier wave radios and mechanical computers. :) But the typewriter seems to be a very good example of an old tool finding new life in a real world situation.
Hint.
HF shortwave is very difficult to DF.
