Cristi, According to Ionospheric Radio (Davies) the geomagnetic variations caused by the Moon are usually small. I believe they are due to the Moons gravitational tug on the ionosphere. My best guess

Cris, I agree - trying to separate out any effect of the moon from other variables will likely prove to be very difficult. This could also be done with exisiting low frequency BC beacons that are the

Carl, This could also be done with exisiting low frequency BC beacons that are there every day - for example, a W6 listening to an Asian beacon every day at the same time for a year as you suggested.

But you would have to know and record the absolute signal level changes referenced to some starting point for a long period of time every night for many nights. I would guess at least a year. The re

Barring disaster, Cris, a MW broadcaster's signal should be very predictable, as their pattern and power is a condition of their licence, and in many parts of the world, the information is in the pub

I'm not sure how badly I want to display the gaps in my knowledge about this problem to those on the list, Tom! My feeling is that the least of the worries is automated recording of signal strength;

Hello Tom, I already said that. In order to appreciate the variation of the signal (especially during a long period of time) on should refer to a calibrated source. This could be a signal stable gene
