Sec. 80.828  Radiotelegraph station clock.

    A working clock equipped with a sweep seconds hand and having a dial 
not less than 12.7 cm (5 inches) in diameter, the face of which is 
marked to indicate the silence periods prescribed for the radiotelegraph 
service by the International Radio Regulations, must be provided. It 
must be securely mounted in the radiotelegraph operating room in such a 
position that the entire dial can be clearly observed by the radio 
officer from the normal radiotelegraph operating position, from the 
operating position where the international radiotelegraph alarm signal 
would ordinarily be transmitted by hand, and from the position used for 
testing the auto alarm (if installed). If a separate emergency 
radiotelegraph operating room is provided, the requirements of this 
section apply to it also.
