Geminids
开云体育Lots of activity from the Geminids can be viewed on the Meteor Beacon Project web site can be viewed live at? This is s prototype display which will be improved in terms of
frequency span and resolution. Also more receivers will be added.?
Here are some examples snapped in the last few minutes:-

Hi brian I have been a member?of the BAA for a number?of years, but have mainly concentrated?on planetary and lunar imaging but recently?I thought I would try radio meteor detection I purchased?a 5 element yagi aerial and a NOOelec SDR dongle and followed the information?I found on the SPA sight for setting up a receiver and software (SDR# and Spectrum lab) I also downloaded their settings for spectrum lab. But I have been unable to get spectrum lab to work. I keep getting the below?problem when running it. Is there a Youtube? video that does a step?by step install and setup for the software as I can receive?local radio in SDR# so I know the Hardware is working. Any help would be gratefully?received, If you know of any one that might be able to help me that lives in the Ferryhill Co. Durham area, and would be willing to have a look at my setup that would be great. Looking forward?to your reply, Merry Christmas?and best wishes for the New Year.

开云体育Hello Alan I see Tony has replied. I have no experience with Spectrum Lab. But please take a look at for the live display of the project receivers currently operational as development continues. Brian

Hi I’ve tried both 7 and 8 of the conditional actions on backwaters site but still having the problem with the unknown sound file as below, this was with blackwaters optional conditions 7! On Fri, 15 Dec 2023 at 16:42, Mike German via <mike.german=[email protected]> wrote:

Hi all
I'm new to this group but I'd just like to say congrats to the team that put GB3MBA on the air, I'm getting some good pings and bursts from it here 500kms away on the south coast of Ireland. I recently used it to find the peak of the Geminid meteor shower...?How I used the 50 MHz GB3MBA propagation beacon to find the peak of the 2023 Geminid meteor shower... |
开云体育Hello John Great to hear that you're using GB3MBA .. makes all the work worthwhile !? The network of receivers can be viewed at . There are only 3 receivers in the network at the moment but we hope to add a fourth located near the Armagh Observatory? soon and another in Scotland when we have a suitable location. The echoes are quite directional so not all receivers see the same echoes so observations from different places are of great interest. All the best Brian On 18/12/2023 10:36, John Desmond via

Hi John Your write-up on your blog site is really good - thank you. As I am only 60km away from the beacon, it is great to see the lack of aircraft trails and direct carrier?on your images.? They make using Spectrum Lab very difficult for automatic recording. In the initial trials?of the beacon when it was being tested in the south of England during the 2021 Geminids, I was able to get a plot over the peak of the shower with my 4 element 6 meter yagi and an Icom 7100 in Leicester with a script in Spectrum Lab. So it is interesting to compare. Tony On Mon, 18 Dec 2023 at 12:24, Brian <brian@...> wrote:

Thanks for the info and link.

I had a listen this morning and I compared my reception to the receiver at the Norman Lockyer Observatory at Sidmouth. I caught one nice meteor scatter burst at 08:53 UTC which was about 45 seconds long.
?
?
The image on the left is from online receiver in Sidmouth and the image on the right is of my SpectrumLab display which is moving vertically at about a third of the speed.?The caveat of course is that maybe there were two separate meteor bursts at the same time but it would be some coincidence considering the low number of long bursts I receive.
?
There is about a 49 degree difference in heading from GB3MBA to Sidmouth and Cork so it's encouraging to see that signals don't seem to be restricted to a very narrow corridor for the 300-500km paths.?It'll be interesting to do some tests when Armagh goes live which will be 383kms at 293 degrees.
?
Just one thought... It would be useful if the remote receivers on the page were grouped by area. Maybe put all of the receivers to the west of the beacon on the left, the receivers to the east on the right and so on. It might make comparing traces a bit easier.

Hi John Your capture is very interesting - it's a long time since I have seen such a long period of reflection. This is unlikely to be just a meteor trail AFAIK. It will likely be a meteor trail creating a patch of sporadic E ionisation which carries on reflecting the signal long after the original seed trail has gone.? Tony?
