Yes, you can.

TG1 (worldwide calling) and TG13 (worldwide English) on slot 1 are often used by DX stations, particularly from the UK and Europe.

Once you have established contact with the DX station on TG1 or 13, QSY to TG113 or 123 on slot 1 – this links only your repeater and the DX station’s repeater, freeing up slot 1 for other stations.

Happy DXing.
