It looks like you've shared a log entry from a radio communication platform, likely a digital mode such as FT8 or some other digital amateur radio system. Let's break down what this text means:
1. **23:40**: This is the time when the transmission occurred, in 24-hour format.
2. **JF1NDT/3**: This is the callsign of the transmitting station. Callsigns are unique identifiers given to radio amateur stations by their respective national regulatory bodies (in this case, Japan). The "/3" indicates that JF1NDT is operating with an amplifier or a repeater, which allows them to increase their power output.
3. **on JP-1575(Hikigawa Prefectural Nature Park)**: This likely refers to the location of the transmitting station. "JP-1575" could be a grid square identifier in the Maidenhead system used for geographic referencing in amateur radio. Hikigawa Prefectural Nature Park would indicate that the transmitter is located within this park, suggesting it might be a portable setup or part of an event there.
4. **10136.0 FT8 RBN -12 dB via JI1HFJ-#[JI1HFJ-#]**: This line gives more details about the transmission and reception:
- **10136.0**: This is the frequency on which the transmission occurred, in kHz.
- **FT8**: This is the mode used for this transmission. FT8 stands for "Mode T" (a digital mode), where 8 refers to the number of tones or frequencies it uses.
- **RBN**: It seems you meant to write RBN, which stands for Reverse Beacon Network. However, in amateur radio contexts like this one, it's more likely referring to a reporting system within specific digital modes that indicates if a station is being reported by a receiver (e.g., "in the log") or not ("out of the log"). The context here seems to suggest it might be discussing signal strength.
- **-12 dB**: This likely indicates the signal strength received at some other station. In radio communication, decibel (dB) measurements are used to express the power level ratio between two signals. A negative value indicates how much weaker the signal is compared to a reference level (often considered to be 0 dBm, which is 1 milliwatt).
- **via JI1HFJ-#[JI1HFJ-#]**: This line seems to indicate who reported this transmission or where it was first noted ("in the log"). It mentions "JI1HFJ", another amateur radio callsign, suggesting that station was the one detecting and reporting this signal. The brackets and hash marks might be part of a specific logging system or identifier format used by digital mode platforms.
This log entry provides details on a transmission from JF1NDT/3, operating in FT8 mode at 10136.0 kHz, located within Hikigawa Prefectural Nature Park, Japan. The signal was reported to have been detected with a significant strength reduction of -12 dB via another station (JI1HFJ), using whatever reporting system is being referenced here.
If you're an amateur radio enthusiast or curious about digital modes like FT8, this log entry provides insight into the specifics of how transmissions are recorded and shared within the amateur radio community.
