It appears you're sharing a ham radio contact information. Here's a breakdown of what the text likely means:

* **09:52**: The time of the contact.

* **JR1WU** (not JR1WVU, possibly a typo): The call sign of the amateur radio operator. In Japan, amateur radio call signs usually start with "JA" or "JK", but in some cases, like when operating as a station outside their country, they might use a different prefix. However, "JR" is not typically used; it seems to be incorrectly stated here.

* **/1**: This indicates the operator has changed their antenna configuration or mode of operation (e.g., switching between voice and digital modes). The number after "/" can signify different things depending on the context and specific regulations. It might indicate a change in operating frequency, band, or mode.

* **on JP-1195(Kashiwa no Ha Prefectural Park, JP-CH)**: This likely indicates the location of the amateur radio station (in this case, Kashiwa no Ha Prefectural Park) and possibly the specific operating frequency (JP-1195), with "JP" referring to Japan. The mention of "Prefectural Park" suggests a very specific and perhaps somewhat off-grid location for the radio operation.

* **145740**: This is probably the operating frequency in MHz, though without further context or clarification, it's hard to be certain.

* **SSB mc ssb[JR1WVU]**: This part refers to the mode of operation. "SSB" stands for Single Side Band, a method of transmitting radio signals where only one sideband (upper or lower) is transmitted. The mention of "mc" seems out of place in this context and might be unrelated; if it's meant to signify something, its meaning isn't clear without further information. The "[JR1WVU]" part seems like a repetition or misinterpretation of the call sign mentioned earlier.

Without additional context or clarification on the "jr" prefix, the specific operating conditions (e.g., what "JP-1195" refers to), and the meaning of "/1" in this context, it's challenging to fully understand the details of this amateur radio contact.
