Hi, I have just come back to amateur radio after a ten break. CW is what I love but it does not love me! I do suffer from tinnitus(Ringing in the ears) at a reasonably low level my idea was not to use phones just to use a speaker. After two weeks of two or three contacts a day. My ears are ringing probably 50% above their usual level and are making life quite uncomfortable. besides giving up CW has anyone any ideas or does anyone have the same problem? Richard G0ILN.
