do you have any plans for a super simple CW reciever? | ||

First of all, I'll bet you can copy CW on a crystal radio. The CW signal will sound like a quieting of the background noise. You might search for phrases like "direct conversion receiver", "NE602 receiver", or "one chip receiver". You will see sites like this and this and this. | ||

Also look up building a coherer. They are very simple (tube of metal filings), and were used in the early days to detect morse code. You can also use mercury, but I wouldn't recommend it! |
