Several hundred usable meteor trails are formed per hour, but since each trail can be used for only one second, the transmitter has to send its message fast. This it does by an electronic mechanism which stores the message and sends it in a "burst" less than one second long. The receiving station has an apparatus that stores the burst and plays it out slowly as an understandable message...

First chance at the new apparatus will go to Canada's armed services and to those of her allies. Civilians may get theirs later...
