Should I learn morse at "both" speeds?

No. Stick with higher speeds. Not only will the slower speeds naturally come along with higher speeds (to some extent, you'll have to practice a bit later on), but learning at a slow speed tends to ...

Converting WPM to CPM

Morse characters have different lengths. A series of Es is much shorter than a series of Os. Therefore, the WPM is perhaps a better choice, because a word contains different characters. Based on the ...
