In American Morse Code, "HO" sounds like "HI" in international Morse Code, "HO HO" became "HI HI". Huh?

  https://en.wikipedia.org/wiki/American_Morse_code https://en.wikipedia.org/wiki/American_Morse_code says that 'o' was encoded as 'dit <space> dit', whereas 'i' was encoded as 'dit dit'. International Morse Code changes 'o' to be 'dah dah dah'. I cannot see any evidence American Morse was used for radio, though it may have been.

  In American Morse, "O" was two dits separated by a space. Intracharacter spaces were eliminated in International Morse Code. "O" became three dahs. "I" is two dits with no space.

  It's probably vandalism: https://en.wikipedia.org/w/index.php?title=OSCAR_1&diff=next&oldid=647297354 https://en.wikipedia.org/w/index.php?title=OSCAR_1&diff=next... A single edit from that ip in a year.

If you think to you might enjoy messing around with satellites, ham radio is pretty easy to get into these days. This is especially true for VHF/UHF, which is what amateur satellites use, and only requires the Technician license. For equipment you just need a handheld VHF/UHF radio (as cheap as $25 for a Baofeng http://www.amazon.com/BaoFeng-UV-5R-Dual-Radio-Black/dp/B007H4VT7A http://www.amazon.com/BaoFeng-UV-5R-Dual-Radio-Black/dp/B007... but I'd recommend a Yaesu, Kenwood, or Icom if you can afford it) and a simple yagi antenna (Google "tape measure yagi", or something like this if you don't want to DIY: http://www.arrowantennas.com/arrowii/146-437.html http://www.arrowantennas.com/arrowii/146-437.html) http://www.amsat.org/ http://www.amsat.org/ http://www.heavens-above.com/ http://www.heavens-above.com/ https://www.youtube.com/watch?v=c0CWz4Emyro https://www.youtube.com/watch?v=c0CWz4Emyro https://hamstudy.org/ https://hamstudy.org/

  Here's a good example of someone "working" a popular amateur radio satellite, SO-50: https://www.youtube.com/watch?v=lhBs5DlKaVU https://www.youtube.com/watch?v=lhBs5DlKaVU
