BINGO!!! You nailed it on the head. In my profession we see this alot. I work for an Internet Service Provider in central Wi and we have wireless towers all over the place in central Wi. Once in a while we will have whats called the Ducting Effect. As the surface of the earth warms up it pushes the wireless signal up, thus making wireless connectivity go goofy for a while. Then as the day goes on and the day cools off, or the heat from upper atmospheredropsthe signal begins to drop to normal range and wireless connectivity begins working properly. You can think of your morning scents as a wireless connection and the ducting effect.This is why I do not use scents during morning hunts.
