Back in the days when there was a lot of radio telephone traffic from oil rigs in the Gulf to onshore stations, I heard an interesting series of conversations between a man and woman.They were on almost every night for a month, romancing each other in AM mode around 6240 Khz. She was in Florida and judging by his accent he hailed from S. Louisiana and was on a rig.
One night while listening for Europirates, I heard her calling him. A different male voice comes back, "He had to quit, honey, his wife heard the two of you talking."
