It appears to be a radio transmission report.

Here's a breakdown of the information:

* `09:36`: The time of the transmission, which is in 24-hour format.

* `JJ1HHJ/1`: The call sign of the amateur radio operator. In Japan, amateur radio operators are assigned a unique call sign that starts with "JA" or "JI", depending on their region. "JJ" indicates that this operator is from the Tokyo (Tokai) region. The `/1` likely indicates an upgrade to a more powerful antenna system, known as a "power amplifier" in amateur radio terms.

* `on JP-2038`: This refers to the location where the transmission took place, using a specific identifier called a "grid square" or "locator". In Japan, grid squares are used to identify locations for amateur radio purposes. The exact meaning of "JP-2038" would require more context or knowledge of Japanese grid square systems.

* `(Imperial Palace Outer Garden National Government Park)`: A descriptive name of the location where the transmission took place. This seems to be a public park in Tokyo.

* `(JP-TK)`: Another identifier for the location, possibly a two-letter code representing a prefecture (in this case, "TK" stands for Tokyo Prefecture).

The rest of the text appears to be an automated message:

* `145240 FM QRT TU[JJ1HHJ]`: This is likely generated by a computer program that reports on amateur radio transmissions. The components are:

+ `145240`: The frequency (in kHz) and mode (FM, meaning Frequency Modulation) of the transmission.

+ `QRT`: A Morse code abbreviation for "stop" or "shut down", indicating that the transmission has ended.

+ `TU`: An indication that the transmission was made in a test mode, possibly for debugging purposes.

+ `[JJ1HHJ]`: The original call sign of the operator, likely included as part of the automated report.

In summary, this appears to be a record of an amateur radio transmission by JJ1HHJ from the Imperial Palace Outer Garden National Government Park in Tokyo.
