Not sure about the code helping one with their spelling. For fun and in preparation for morse code
competitions we would get a bunch of guys together and do the round the table game. The only difference was that the code was
alternately sent forwards and backwards.
The guys who worked radio were something else since they acquired the nack to hear words instead of letters just as you posted
about reading. Almost required when communicating at high speed.
I sometimes wondered how those guys didn't go bonkers. Paricipating in a world wide competition were you don't sleep for 24 to 36 hours and just sent and recieved code. After that i would be translating dit's and dah's in my head for about a week. You go to the grocery stores and and try to makes sense of the sounds comming from the cash register, rattle from the car, etc , etc. But must say that i did learn to
appreciate how a secretary could talk to you while she was typing. BTW, she wasn't blonde though.....
