what that 45 baud is 60wpm in bauddot mean?the standard was chosen for all baud rates, even morse code. thats why 100 baud is 100 wpm in ascii, and 45 baud is 60 wpm in baudot code..
No it won't, most of us old Navy radio guys could tell what it was in a instant and decode just about any possible RTTY signal using gear from the stone age.You can record the audio output and then decode the playback. Probably wouldn't fool the NSA for long though.
They were using Morse Code, which has ABOUT 4 bits per character on the average. Dash is three times the length of a dot with "correct" morse code.Transatlantic cable in 1880's can transfer 8 words per minute(approx 5bps per second)
I have seen this in video. In general does the the word have any specific bits or the bits of the word change accordingly
;
; Some general information about Morse Code Speed;
;
; <1> A Dash is three times longer than a Dot
; <2> A Dot space is used between Dashes and Dots within a character
; <3> A pause between characters is three Dots long
; <4> A pause between words is seven dots long
;
; The word 'Paris' was established as an international standard
; for calculating the speed of Morse in words-per-minute (wpm)
; and characters-per-minute (cpm)... This works out to 50 dots
; (or dot times) per word and yields the following timing;
;
; 5-wpm ( 25-cpm) = 60 / 250 dots = 240-msec / dot
; 6-wpm ( 30-cpm) = 60 / 300 dots = 200-msec / dot
; 7-wpm ( 35-cpm) = 60 / 350 dots = 171-msec / dot
; 8-wpm ( 40-cpm) = 60 / 400 dots = 150-msec / dot
; 9-wpm ( 45-cpm) = 60 / 450 dots = 133-msec / dot
; 10-wpm ( 50-cpm) = 60 / 500 dots = 120-msec / dot
; 15-wpm ( 75-cpm) = 60 / 750 dots = 80-msec / dot
; 20-wpm (100-cpm) = 60 / 1000 dots = 60-msec / dot
; 25-wpm (125-cpm) = 60 / 1250 dots = 48-msec / dot
; 30-wpm (150-cpm) = 60 / 1500 dots = 40-msec / dot
; 35-wpm (175-cpm) = 60 / 1750 dots = 34-msec / dot
; 40-wpm (200-cpm) = 60 / 2000 dots = 30-msec / dot
; 50-wpm (250-cpm) = 60 / 2500 dots = 24-msec / dot
