Reel to reel sounds like fun. I've always wanted one. Is it possibble
to record cw and play it back at a slower speed? ............

Sure. But you can also do that using windows sound recorder.
Also, as mentioned, you can get software to decode it in real
time, or....maybe I'll let you rent my brain if you really want
good copy... :/ Not sure what to charge for that service though... MK
