[QUOTE="PaulR, post: 848758, member: 176256"] More or less - yes. The high pressure causes the signals to travel further without attenuation. There's also another phenomenom around at this time of year called Sporadic E although it doesn't really affect UHF frequencies. It's mostly notoceable on VHF and the top end of HF transmissions. Many years ago I was driving down through Shropshire listening to FM radio. This was before NF (Network Follow) and I had to keep scanning for a different transmitter. Suddenly a Spanish radio station (or maybe Italian - my language skills are none too good) came booming in. I was able to listen to it for about twenty minutes as I drove south until it just as suddenly faded away. [/QUOTE]
