The timings agree with the sort of thing I would expect. There should be a very distinct "low" at dusk and at dawn due to the fact that the path is predominantly north-south. The rising sun stimulates absorbing ionisation in the D-layer almost simultaneously along the whole path. The result is a dramtic "crash" of signal levels at dawn. As the sun rises higher some of this reaches levels to become "reflecting". Brian sees this effect on his path to the UK. Last night was not too good. Signal levels from CFH were down on the recent nights, with deep fades. Great test....hope the comms and power holds up ok. Cheers de Alan G3NYK alan.melia@btinternet.com
