So, I've got this code below.  The tone section sends 2 characters in morse code "CQ"; which equate to a tone sequence like this: long short long short    long long short long

Initially I had the timing for each tone inverted from what is in the code, to match the tone sequence above.  What I found was that after compilation, this sequence was *inverted*.  So, I'd get short long short long      short short long short; I found that if I inverted the duration then it played properly.

The funny thing is; I initially had a single character and it was correctly "played".

Is there something I'm not thinking of that would cause this behavior?

I realize there would be better ways to do this; I was simply fussing around with GCB and a breadboard and found this behavior a bit odd.

Thanks,

Joe
