By the time August comes along, the Es openings on the VHF bands are generally dying down a bit. Certainly, I've been checking 50MHz less frequently from the car and I've even been thinking about what band I'm going to use the IC706/mobile for over the winter (more on that soon!).
However, chatting to Ken, G3LVP this morning about 70MHz, he told me that yesterday there had been an opening to Portugal on 70MHz. Ken had worked CT1FJC from the Algarve.
So, keep checking those bands!
