OTC Sydney :

 

This station was formerly named AORTS Sydney

 

The major terminal of Australian overseas telecommunications was very active, here 1974 in CW...
...and here 1974 with a voice mirror - hard to identify with the broken tape! (both: rb)

 

nice QSL card (Martin Foltz, 1975) - watch out for the return channel...
