Whoops! Here is the link!
Hello,
Thanks for the answers!
Is it this project ?
I'm gonna check it out, but it looks like the idea is in there, thanks!
Anthony
Hey Kevin, I don't see the link that you mentioned, did you forget to include it?
Hi Anthony:
Check out this link. The author is using a Pluto but he developed a flowgraph to transmit a vector that represents Morse code. Pretty well-explained. The ideas you need are likely in there.
