Here is my simple CW RST system when you don't have an S meter, Only 5 levels: 119 No Copy, but i would like your QSL card from you if you can copy me. 339 Just enough to guess your call sign, you are in the log. 559 Got your call and name and maybe your QTH 579 Got it all. 599 Blasting into my earphones, had to turn the audio down.
