I’m sure that happens to all of us. Fortunately, I find most chasers are very patient and tolerant.
Also, I’ve noticed my sending and receiving are so much less effort sitting in my quiet, comfortable warm shack [temporarily transferred from an unheated outbuilding to the upstairs ‘guest’ bedroom] than on any SOTA activation where rain, wind, wind noise, cold fingers, my sitting/crouching posture, low-flying jet noise, inquisitive walkers, inquisitive cows, biting insects, antenna-support chewing sheep, etc, etc are distracting me.
Oh an antique! They were no longer being issued by the time I was first licenced in 1990. Wow 34 years this summer for me!
EDIT: I stand corrected. I do have an Radio Amateurs Certificate but it’s a jolly City & Guilds one not a Home Office issue.
I also found my Morse pass. It was in the licence and CEPT printout I take when travelling. That dates from when you still needed a Morse pass in some countries as they had not put the ITU changes into practice. That pass certificate has been to Europe regularly for the last 20 years
The Radio Amateur’s Certificate and the Amateur Radio Certificate are two different things! The former is the certificate from City and Guilds to say you have passed the RAE. The latter is to say you have passed both the RAE and the morse test and are entitled to a licence.
