In reply to GM4FAM:
Thank you to everyone for all your comments, which are greatly appreciated.
CW is my personal choice of operating mode because it gives me so much satisfaction. After more than 50 years of using Morse code I still experience a warm feeling of pride and achievement after a successful QSO.
However, with only room for a vertical antenna in a small garden, CW is more of a necessity at this location. In amateur radio you make the best use of whatever resources are available, so I am pleased and relieved to have reached this personal milestone albeit without the use of 2 metres, 5 MHz or SSB.
Thanks to all the dedicated activators in the UK and across Europe, without which this would have been a fruitless task. I have made a lot of new SOTA friends.
