You need to keep using it in order to stay proficient but you don’t really lose it all. This was not due to lack of interest, from what I can tell, but lack of time.

I passed the test 1st time out because of the work that he put in.Įver since I got licensed after passing the 5 words per minutes code requirement, I did not touch it again. A local ham who is SK now bent over backwards to help me learn morse code by sending to me over the air and allowing me to use tapes that he had to practice copying. I was always told it is better to try and practice at 13 word per minute as you can pick it up better with the right spacing but I never made it that far.

To upgrade to General, you had to learn 13 words per minute and to upgrade to the Extra Class, you had to learn 20 words per minute.

If you are up for the challenge, however, you could probably build one with more esoteric components, such as an EEPROM+counter, or even a music-box type mechanical system.In order to get my first license (Technician Plus) with HF privileges, I had to learn morse code at a level of 5 words per minute. Mark admits that using an Arduino for this is a bit of overkill, however I think that convenience trumps component cost for one-of projects like this. Each character takes only a single byte to store its pattern, and decoding is just done in a few instructions. We then get rid of that element (by dividing by two, or shifting right if that floats your boat) and repeat. If it is a zero, we have a dit, if we have a one, it’s a dah. If not, we look at the least significant digit. If the pattern is equal to one, we are done (that’s our guard bit). Then, when we are looping, we do the following. The only trick is knowing when there are no elements left, because otherwise we can’t tell (for example) K (-.-) from C (-.-.) To do that, we store a single extra one after all the other elements are taken care of. Lets store them so the first element gets stored in the least significant bit, and the next in the second most, and so on. Let’s say that dits are zero and dahs are one. Morse code characters are all length six or less, and each element is either a dot or a dash, so it would seem that we can store the pattern in six bits. It’s a little bit clever (a very little bit) but I guess it does require some explanation.
I really like the clever way that he stores the code sequences for each character: Graphics and More to Help Spread the WordĪny hams out there that need a quick-and-dirty morse code beacon?
