I'm still in the middle of that process, but finally decided I had enough knowledge and information to use a tool, and see what I could achieve in the way of a DX contact to Europe on 15m and what the best time might be to achieve that. So, the data I had told me that if I started around 4am UTC, I could likely begin to hear Europe and have some success until around 10am UTC. With that in my mind I gamely set out to do exactly that. I was busy at 4am, so I postponed to around 6am UTC and tried my luck. Nothing, not a sausage.
