It seems you've provided a transmission report from a ham radio operator. Let's break down the information:

* `04:58` indicates the time of the transmission.

* `JF1CMH/1` is the call sign of the transmitting station, which identifies it as a ham radio operator in Japan (the "JF" prefix is used for amateur radio operators in Japan).

* `/1` suggests that this is the first station (or antenna) being used by JF1CMH.

* `on JP-1304` indicates the location of the transmitter, specifically the Hodogaya Prefectural Park in Kanagawa prefecture, Japan. The "JP-" prefix identifies it as a location within Japan.

* `(Hodogaya Prefectural Park, JP-KN)` is likely additional information about the location, including the name of the park and the prefecture (Kanagawa).

* `7000 CW` indicates that the transmission was in Morse code (CW stands for Continuous Wave) on a frequency of 7 MHz.

In summary, this report says that at 04:58 JST, ham radio operator JF1CMH transmitted a CW signal on 7000 Hz from Hodogaya Prefectural Park, Kanagawa prefecture, Japan.
