It appears to be a log entry from a ham radio operator. Here's a breakdown of the information:

* `07:50`: The time of the transmission.

* `JR1WVU/1`: The callsign of the transmitting station, with `/1` indicating that it's a substation or repeater (not the main station).

* `on JP-1195`: The location of the transmitting station, which is identified as "JP-1195". This likely corresponds to a specific geographic coordinate or grid square.

* `(Kashiwa no Ha Prefectural Park, JP-CH)`: Additional information about the location, including the name of a park and a reference to Japan (JP-CH).

* `10113`: The frequency on which the transmission occurred, expressed in a numeric format that is likely a combination of kilohertz and band identifier.

* `CW CW`: The mode of transmission, which is Continuous Wave (CW) radio communication. This is a type of Morse code transmission.

* `JCC1217[JR1WVU]`: A unique identifier or log number for the transmission, possibly associated with a specific contest or logging system.

Overall, this appears to be a routine entry in a ham radio operator's logbook, documenting a transmission from one station (JR1WVU/1) to another.
