Quoteyeah, i should probably change that to 'pitch'
no - hams usually call it a tone control, i used the term pitch to be more technically correct, is all

the WPM change - needed
prosigns - needed
the iambic keyer thing - i was pulling your leg - i didn't expect you to implement that - lol

dedndave

the most commonly used prosigns are AR, BK, and KN - oh - and double-hyphen (BT)
use an alt-key combo for those, or maybe the function keys

you need the error symbol (8 dits)
i would think you could use the backspace or delete key for that one

if you have those, letters, numbers, and "/", and "?", you have the common stuff

EDIT - add period and comma to that list   :bg

oex

i plan on adding all the punctuations on this list.

i don't know what an error code would serve.  i don't think this program will ever evolve into a receiver/transmitter.
i may add in the AR prosign.

i doubt it will make much difference, but i'm also thinking of rewriting the tables into two byte pairs, one byte for length and another to encode the bits.  i don't think there are any codes more than 8 bits.

dedndave

that list has a couple items that never get used
this one is a little shorter, i think
and - it's all the commonly used stuff

new version
https://sites.google.com/site/highlevelassembly/home
https://sites.google.com/site/highlevelassembly/downloads/morsecode.zip?attredirects=0&d=1

changes:
removed pause/duration for a straight out wpm layout.
now saves user settings to an ini file.

plans for next update.
a trainer mode which sounds a code and waits for keyboard input.  haven't decided yet, i may go with the koch method, starting with 2 characters at level one and working up to the full set of 40 characters at level 39.  the "levels" might appeal to the younger mmorpg crowd and draw some of them in.

that sounds a little better, Sevag   :U

they call it packet radio - lol
in fact, the link layer protocol used in the modern internet was fashioned after ham radio's AX.25
if you read the old specs, you will see a lot of amateur radio callsigns pop up

Actually... those of us that were around back when packet started know that AX25 and amateur TCPIP were both created based on the internet. AX.25 was based on the X.25 standard that was already in place at the time...AND  Phil Karn KA9Q wrote a lot of software for both amateur and internet based networking...
