Hi
i started to learn CW about 4mo ago. I can recognise pretty well words at max of 15 WPM when listening to YT or Morse Mania, and QSOs on the air also, but got issuses when I'm trying to make my own QSO - sometimes especially when there are some QSBs my brain just freezes, I can't copy any word - and I'm afraid to ask operator to send again entire statement. How do you manage such situations?
