This appears to be a radio transmission report in the format typically used by amateur radio operators. Here's a breakdown of what each part means:

* "09:35" refers to the time of the transmission, which is 9:35 AM.

* "JR1WVU/1" is the call sign of the transmitting station. In Japan, amateur radio call signs typically follow this format, where "JR" indicates the country (Japan), and the numbers and letters that follow identify the specific operator or station. The "/1" likely refers to a mode of operation, possibly an antenna system.

* "on JP-1195(Kashiwa no Ha Prefectural Park, JP-CH)" indicates the location where the transmission was received. In this case:

+ "JP-" is the country code for Japan.

+ "-1195" likely refers to a specific location or grid square (in a format used by amateur radio operators to locate each other).

+ "(Kashiwa no Ha Prefectural Park)" is the name of the park where the transmission was received.

+ "JP-CH" indicates that this location is within Japan's Chiba prefecture.

* "430210" appears to be a signal report, which is a subjective assessment of the strength and quality of the transmission. In this format, each number represents a certain aspect of the signal (e.g., 1=very weak, 2=weak, 5=average, 7=strong, 9=very strong). A total score of "210" indicates that the signal was assessed as being around 2 points for the first digit and 10 points for the second.

* "SSB ssb[JR1WVU]" refers to the mode of transmission (Single Side Band) and the call sign again. SSB is a type of radio modulation used in amateur radio and other communications, allowing only one sideband to be transmitted.

So, this report indicates that at 09:35 AM, JR1WVU/1 transmitted on single-side band from Kashiwa no Ha Prefectural Park, Chiba prefecture (JP-CH), with a signal strength of around 2 points for the first digit and 10 points for the second.
