Wow so true I had forgotten about the burst CW, excellent info Radio Ray! These days wide band RX can pick up everything for later analysis so this would not be so secret but back then unless one knew in advance the time and frequency it'd have been nigh impossible to capture transmission by enemy. I know a former submarine CW OP and that's exactly what he used to do, they'd surface, send the burst, and dive again.
