It looks like someone is activating a Summit On The Air (SOTA) event!

Here's what I can gather from the message:

* JG1BOK: The callsign of the person activating the SOTA event.
* JA/NN-076: The Japanese SOTA activation zone for Kirigamine (Kurumayama).
* 1925m: The altitude of the summit being activated.
* 10 pts: The number of points that will be awarded for this activation.
* 7.030 cw: The frequency and mode being used for the activation (7.030 MHz, CW - Continuous Wave).

The [APRS2SOTA] tags suggest that this message is related to Automatic Packet Reporting System (APRS) and SOTA events.
