morse code as is. i know most of radio amateurs these days inclined not to have it anymore but as we go back in time and understand the reasons why they have the cw, its because, cw provides the most reliable mode of communication even if the propagation on the HF bands were low. thats true, the high pitch tone of the cw enables the ssb radios to deliver maximum rf output thus making it possible to reach more distance as compared to voice communication on the ssb. you'll understand it better if you are an operator of ssb radios on the hf bands. one more thing, cw separates ham operator from bootleggers. hihi. 73 de dv1vss
