Thanks to Martyn M1MAJ for the video – he goes on to say:
The summit, Y Llethr, was a fine one for playing radio: a wall for shelter, a nice flat grassy area for antennas, and wonderful views. I’ve attached a more distant view of the station as there’s not really a lot to see of it in the video.
One thing we really noticed on our summit contacts was that the audio quality of GS3PYE was superb.
