Navy Buenos Aires:
They confirm that I received them in RTTY, but of course it was in voice. In 1973 I was allowed to take a look at the VHF and UHF antennas up on the roof of Navy HQ and also to visit their HF comcen elsewhere in the city. While walking around there I was constantly followed by two armed guards and their dogs. But they were very friendly and offered me a lunch before I left. (MvD)
