Re: Meteor Project update
Hello Mike
The plan is to install the 3 principle receivers at least 300km
from the beacon which greatly reduces aircraft reflections. The
next installation is scheduled for a site close to the Armagh
observatory and I hope that will see fewer aircraft. My
installation is only for system testing and is too close to the
beacon.

Re: Meteor Project update
Thank you Mike. I hope you will find the GB3MBA beacon and the
data streams from the receiver network, when fully operational, of
use to your studies especially of meteor events over the UK.

Re: Meteor Project update
Hi Brian
It's great to have the receivers displayed together like this. A few minutes watching from Goa in India, showed no correlation as indeed we have largely found. We do need to see how we can extract science from these random streams. I'm not sure if Sir Bernard cracked that one. I've been reading a book about radar called 'The Invention the Changed the World' - the story of radar from war to peace. It says that the Missile Early Warning systems studied meteor trails in great detail to characterise them from missiles. So some of that research might be worth pursuing.

Re: Meteor Project update
Hello Andy
In the first instance just take a look and start to think about
the information we might gather. The first thing I find
interesting is that echoes seen by one receiver are often unseen
by others. This speaks of the directionality of the reflections.
Note also that sometimes very different Doppler shifts are
observed for the same event viewed from even similar directions.
The bearings from the beacon to? NLO and Hampshire are not very
different. Maybe the event occurred between NLO and Hampshire ??
Other basics to look for include extent of Doppler on head echoes
( we are not yet displaying this as clearly as we wish) brightness
and duration of head echoes. (Again we hope to be able to provide
better resolution as development continues.) Duration brightness
and spectral spread of Tail echoes. Thoughts on the strange
epsilon echoes we see.? We are at the start of this adventure.

Re: Sudden increase on 22.1kHz 24th November
Hi All
I saw the same peaks as Mark reports. It is a big abrupt change in received level and suggests that it is a transmitter effect. Its is a fast change in output level for a powerful transmitter to make. I did a quick check and it is outside the HAARP test transmission dates. Its interesting that the level change during the night was slowwer to take effect and that the transmitter appeared to go off air at the start and finish.
One thought, does Skelton have a main and standby antenna? This may be a change over test.

Re: Sudden increase on 22.1kHz 24th November
Hi guys,
We also noticed this peak at 22.1kHz in Italy, but we thought it was a problem with the transmitter.

See attached plot. There were no flares or mag. events at

It started at 12:59:55 and ended at 14:12:01.
It's suspicious that it starts nearly on the hour and there
is a also a similar peak that starts at 20:04
and drops at 20:54 just after a short break in the
transmission.

It's not local interference as it sows up on loudet's

Presumably it was a change at the transmitter?
