In the interest of full disclosure I must admit that about 90% of my HF activity is on CW. I took my first license exam in 1949; it was for a Class B license which was two years before there was a Novice class and required a 13 words per minute (WPM) code test. My Elmer, God bless him, wouldn’t let me take the test until I could copy 18 WPM. I did five minutes of solid copy and ever looked back. By then code was easy and fun. The other side of the equation is the technical superiority of CW as a communication medium. It all comes down to bandwidth. A SSB signal takes up a minimum of 2.8 Khz up to 10 CW signals can be placed into that same slice of frequency spectrum if your receiver has a narrow CW filter. The amount of noise and interference you can hear is directly proportionally to the width of your pass-band. It gets better. Most relatively modern radios have Digital Signal Processing (DSP) which allows varying your receiver's band width. In addition, DSP can also peak or null a signal in the pass-band, a S9+ signal a in the pass-band can be reduced to nothing and a S3 signal can read with ease. Try that with SSB. CW has a major advantage, especially in you are running low or moderate power. |
