I did my first CW activation this year and have done a few more since. I agree with Armin - it will be wonderful! In my experience then and since the chasers are super helpful and patient.
If you have a memory keyer in your rig, I find it very helpful to have a CQ call in there and also the summit ref in another memory if you can. There’s a risk I’d run out of daylight before getting the summit ref out correctly - especially in the excitement of an S2S and this makes it much easier!
