I will create some custom mp3 files with 20wpm code with large spacing. see how that goes, i was thinking the other day some of the characters are a bit too slow at 12wpm as you can still hear the dits and dahs and i learn it so much better when i just hear the sound, the best letters personally for me at the moment are O,M,H,B,E,I,T as i hear the sound and not the dits and dahs.
Yeah i have heard the receiver for its size is fantastic. I am thinking of going for 30m, just because its a cw band.
apparently there is a forum about these and a case you can get off ebay fits it nicely. I just don’t have any test equipment bar a cheap multimeter so can’t test the coils etc when building. Although i think a guy at the radio club will have some i can use if need be.
