Re elements pointing at TX that’s the element ends of course

Tony In my now dim distance professional life I built a microwave anechoic chamber and used a phase shifter to balance out background reflections and I do know how sensitive the nulls are even under

Hi Mike I am even closer than Dave - Leicester, and get a strong direct signal. I have done a lot of experiments with a vertically pointing Moxon and secondary dipole antenna with phase shifter to

Hello Mike Dave's receiver system is using an indoor HB9CV type antenna in his apartment loft space. This is an elevated location with a good path towards the beacon hence the strong direct signal.

Peter, Thanks for the Mail. Pleased that you enjoyed the Ballet. I must confess that I have only been twice (Moscow and Covent Garden) and was so surprised that I enjoyed it a lot. The Friday RAZOOM

Thanks Paul, I didn't get the link earlier but never contacted you as I couldn't make it, but will be sure to watch the video when it is released. I took my wife and granddaughter to see Swan Lake

Yes please Mike Many thanks Mike

Just realised you need to be a member of IMO to see that paper. ?If anyone is interested send me an email for a copy

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

I think the biggest problem we both have is sorting the wheat from the chaff.? AIrcraft on the beacon and local interference for me :-(

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. Brian

The reason why some stations see a meteor and other don't can be found in WGN, the Journal of the IMO 51:4 (2023) pp72-92. Regards Mike --- /\ _/\/ \ / \/\ Mike German Hayfield in High Peak

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

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
