I had the beam pointed at GB3VHF but noticed another signal on the waterfall around 144.415.590Hz. I moved the beam to 80 degrees, and it was the PI7CIS beacon on the sea shore of Scheveningen, around S3-4.
Using CWGet I decoded the following CW around 11:36UTC, 6/6/18 :
pi7cis jo22dc 50w dipole 90/270
