It looks like you're sharing a radio transmission report!
Here's a breakdown of the information:
* `06:47`: The time of the transmission, in 24-hour format.
* `JF1CMH/1`: The callsign of the transmitting station (a amateur radio operator in Japan).
+ `/1` indicates that this is a mobile or temporary operation (as opposed to a fixed base station with a `.2` suffix, for example).
* `on JP-1304(Hodogaya Prefectural Park)`: The location of the transmission. In this case, it's in Hodogaya Prefectural Park, on a frequency block known as JP-1304 (a specific allocation of frequencies in Japan).
* `JP-KN`: The country code for Japan (K denotes the Japanese amateur radio license class K), which confirms that the transmission is from within Japan.
* `28045.6 CW`: The transmitted frequency and mode:
+ `28` indicates a band in the range 10-14 MHz, likely the 10-meter band.
+ `045.6` specifies the exact frequency, measured in kHz (2456 kHz = 2.456 MHz). The decimal point is likely used to indicate a fractional part of the frequency (in this case, one-tenth).
+ `CW` indicates that the transmission was made using continuous wave (a form of Morse code transmission, where a variable tone replaces the traditional dots and dashes).
* `RBN`: A reference to the Reverse Beacon Network (RBN), an online service for hams to share reports of distant stations received on specific frequencies.
* `9 dB` and `20 WPM`: These are additional details about the signal strength and transmission speed:
+ The first value (`9 dB`) might indicate the signal strength relative to a reference level, often expressed in decibels (dB). A higher number would mean a stronger signal.
+ The second value (`20 WPM`) specifies the transmission speed. `WPM` stands for words per minute, and 20 is likely indicating that the transmission was sent at a rate of 20 characters (or more precisely, "words") per minute.
The text within square brackets `[ZL4YL-#]` seems to be a reference to the relay station or repeater used by ZL4YL (# might denote the `#` prefix on a specific frequency band).
