It appears to be a Morse code transmission:

`JQ2DUX/2` is likely a call sign ( radio station identifier)

`JP-1458(Ishimakisan Tame Prefectural Nature Park, JP-AI)` seems to indicate the location of the transmission: Japan, specific park and prefecture ( possibly Nagano or Aichi? - Ishimaki'san Tame is not well-known but could be a mountain).

The number `7006.0 CW` suggests that the station is operating on a frequency of 7,006 kHz.

Finally, `[JQ2DUX] QRT` appears to indicate that the transmission is ending or has ended ("QRT" stands for "Quit Radio Transmitting").
