Morse Code

Morse Code, you cannot be serious?! Oh, yes I can. And I am! You may argue, as many do, that morse is a thing of the past. In some aspects it is, of course, but in spectacularily many aspects it definately is not! Single Sideband (phone) is no doubt easier to grasp in a quick time but the efficiency of the latter is some 13 db lower! This is a fact that stems from the required bandwidth in the two modes. SSB is almost 3 kHz wide while a morse code signal happily will fit within 100-150 Hz. When the available output power is smeared out over either 3 kHz or 150 Hz, which signal will be “brightest” do you think? Clearly morse!

Morse code has a heritage of over 100 years but despite modern advances in communication there is hard to find any means of communications that gives more bang for the buck. The readability despite interference is widely recognized. The high QSO rate too. And the hardware requirements are very modest: it is quite feasible that power that is not enough to even light up a flashlight (a watt or two) will travel thousands of kilometres! If you are into constructing your own electronics you will be pleased to know that a morse code transceiver is a lot easier to construct than a SSB one.

It is too difficult you say? Perhaps not any longer. Look at the Koch method in the pane to the left.

By doing it the morse way you uphold a 100+ year old tradition of telegraphy. And it is a fun mode of operating too.
