However, such "polar keying" (originally "polarized keying"), those are implemented as TRINARY since there is the state where no current is flowing in the loop . . . Welp then that means CW is a tertiary mode. Given a slice of RF spectrum space in which CW is being transmitted there are actually three states: Key down, key up and the noise between up n' down. OYeah, the noise matters as a "state". Morse code is definitely BINARY. Binary does not refer to the time or duration of maintaining either of two states. None of that really matters to any policy discussions. It matters greatly to those chat-roomers or morse-bloggers who MUST fill space with all kinds of miscellaneous dreck subjects reveling in the sanctity, efficacy, nobility . . . Sweetums for God's sake it's drek . . as in "Drek mit Leber" . . w3rv |
