This text appears to be a short message from a ham radio operator. Let's break it down:

* "JQ3FIN" is the callsign of the transmitting station.

* "/P on JP-2089(Tamba-no-Mori Prefectural Park, JP-HG)" means that the transmission was made from a park or other public location (indicated by "/P") in Japan, specifically at Tamba-no-Mori Prefectural Park, which is located in the prefecture of Hyogo (JP-HG).

* "7041" is the frequency on which the transmission was made. In this case, it's likely a amateur radio frequency, and the number "7041" corresponds to 70.41 MHz, a common frequency for FT8 operation.

* "FT8 QRT[JQ3FIN]" means that the operator has finished transmitting (QRT stands for "quit radiating") on that particular frequency using the FT8 protocol. The square brackets around the callsign "[JQ3FIN]" likely indicate that it's being used as a identifier.

So, in summary, this message is announcing that JQ3FIN has stopped transmitting on 70.41 MHz from Tamba-no-Mori Prefectural Park.
