I'm sorry, but someone PLEASE correct me if I'm wrong. Isn't this list for
VISUAL satellite observing? I work with satellite and radio astronomy
frequencies all day long, but VISUAL satellite observing is a hobby for me.
I subscribe to this list because I like the hobby, not so I can discuss kHz,
MHz, transmitter power levels, and the wavelength of water vapor when I come

  Thanks for letting me give my opinion,
  Ralph McConahy
