That was a Navy gig so I was cordially commanded to attend. I was with the Navy Show band at the time and Cape Verde is where we kicked off our West Africa tour. We couldn't entertain the locals there because they had no safe AC power source in 1988. That's another story in itself. We had to wait to wait a week for the P3 Orion to come back to pick us up. I loved that plane.
We also did a few days in Senegal and most other countries in West Africa. All told it was about two months there and then on to South America for 6 months and another month in the Caribbean.
I had my ham ticket on that trip and while in Zaire met Tom Gregory N4NW operating as 9Q5NW in Zaire. At the time he was the communications officer for the US Embassy in Kinshasa. He had a few of us over to dinner and then turned me loose on his big gun station to be DX for an hour or so operating as 9Q5NW. Best time I ever had on the radio.
