It appears to be a radiocommunication log entry. Here's a breakdown of the information:

**10:33**: The time of the transmission, in 24-hour format.

**JR1WVU/1**: A unique identifier for the transmitting station, which is likely a amateur radio call sign (Japan has its own prefix JR).

**on JP-1195**: This suggests that the transmission is being monitored on a specific frequency, JP-1195, within the amateur radio band.

**(Kashiwa no Ha Prefectural Park)**: The physical location of the transmitting station, which appears to be a park in Japan. Kashiwa no Ha is actually a mountain located in Chiba prefecture.

**JP-CH**: This likely indicates that the transmission is taking place within the Chiba prefecture of Japan (JP stands for Japan, and CH stands for Chiba).

**430021 CW QRT**:

* **CW**: Indicates that the transmission is using continuous wave (CW) modulation, which is a technique used in amateur radio to transmit Morse code.

* **QRT**: A signal that means "stop" or "finished", indicating that the transmission has ended.

**TNX[JR1WVU]**: This suggests that the person transmitting from JR1WVU wants to thank (or send gratitude) to their own station, perhaps as a courtesy or acknowledgement.
