It appears you've provided a snippet of radio transmission data. Let's break it down:

- **08:21**: This is the time in military format (24-hour clock), indicating when this transmission occurred.

- **JR1WVU/1**: This seems to be the callsign or identifier for the transmitting station, possibly in amateur radio context. The "/1" might suggest a modification or variation of the base call sign JR1WVU.

- **JP-1195(Kashiwa no Ha Prefectural Park)**: This could be the location where the transmission was taking place, indicated by the prefix "JP" for Japan and "1195" which possibly stands for a specific geographical identifier. However, it seems more likely that this is referencing a park or area known as Kashiwa no Ha (which means "pine tree grass" in Japanese), used to identify the location.

- **JP-CH**: This could be a further specification of the location, potentially indicating Chiba Prefecture in Japan, given the prefix "JP".

- **28045 CW CW**: This might refer to the transmission frequency and mode. "CW" stands for Continuous Wave or Morse code transmission. The numbers 28045 are likely referring to the frequency on which this transmission occurred. It's a standard practice in radio communication to specify frequencies using a specific format.

- **JCC1217[JR1WVU]**: This seems to be an identifier or key part of the transmission, possibly related to logging or tracking the communication event. The "[JR1WVU]" suggests that this information is associated with the callsign JR1WVU/1 mentioned earlier.

In summary, this appears to be a snippet from amateur radio communications involving a specific station (JR1WVU) transmitting on a particular frequency from a certain location in Japan.
