CW is without any doubt in my mind the greatest mode of communication there is on HF bands. Rather just having a nice qso in Morse Code or DXing . Weak signals , low power , simple transmitters , simple wire antennas , long distance , Top Band DXing ect .... CW will I think live as long as we are allowed to use the HF frequency spectrum .
I'll tell you what I did today.
I made a contact with AA1TJ in VT, me in GA. This was with CW. AA1TJ is an experimenter. He gets joy out of using as little power as possible. His rig of choice today was made on a bread board using a Raytheon sub-miniature tube. Total power around 40mW with a perfect match. For those that do not know, 40mW is about the amount of power you get when you rub a balloon on your head
I gave him a 339 and he was weak but if he had slowed down and increased the length of the elements we could have carried a conversation. 920 miles with only 40mW. It is contacts like those that make every minute invested learning CW well worth it!
