Hi Tom!
I think I agree that CW might be easier and better. And, thanks for clueing
me in about programming CW vs. beeps.

richard,
Overall CW is more efficient and more accurate than a string of up to 9
beeps. Particularly over a count of 5, humans are just more likely to miss
count, particularly when running about a park like some kind of blind ham!
<GRIN>
The morse numbers each are doubly redundant in that you can count the dits,
the dahs or both thus improving your likelyhood of getting it right.
As for programming the code it's trivially easy unless the poor guy is at
the limits of his microprocessor's program memory and that's unlikely.
hope that makes sense.
