1. US Mil helo flying the southern border near Brownsville / McAllen TX.

Beech Pegasus trainer flying nearby.

1. 3 more Beech Pegasus trainers in southern AZ over Tohono O'Odham reservation. This appears to be a routine flight training activity.

The Beech Pegasus is (solely I believe) used for pilot training with seats for trainee/pilot, instructor, + 2 extra seats that can participate in radio comms.

Your 7016 kHz morse signal is in the Extra (license class) part of the 40 meter ham radio band and it is totally normal, commonplace, for hams to transmit morse code in that part of the band. Your other frequencies I don't recognize as being anything in particular. Use a narrow filter (250 Hz) if you want to listen to the morse code.
