Re: Interesting magnetometer trace

 

Hi Andy,

not seen anything?particularly unusual around then today - maybe some local interference?

Here's my plot for today so far.

Re: Geminids

 

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!

Hallo Alan,

I guess you are using GRAVES transmitter.? If so , there is an excellent Spectrum Lab Conditional Action script at to sort things out for you. Spectrum Lab is very versatile but can take a while to get to grips.

Also another useful page with links is BAA’s worn RA section J

Hope this helps

Re: Geminids

 

I'm also receiving a decent number of pings from GB3MBA at the Wessex web sdr site. Grid Square: IO80qr

Ant1 is a Vertical Terminated Delta loop with 2m sided, fed at the apex 20m AGL.

Ant 2 is a Tri-band 6m, 2m & 70cm vertical collinear at 22m AGL.



The websdr is using the Tri-band vertical collinear



The Flydog web sdr is using the Terminated Delta loop



If you can provide me with some information WRT how you're receiving and uploading the spectrum plots to your streaming website, I can see if I can add an extra RX at Wessex too.

Regards,

Martin


Re: What is happening with Graves?

I’m picking meteors up now and got rid of whatever this constant signal is – suspect wasn’t anything to do with Graves.

Seen some nice meteors visually too – quite bright – now clouded over.

Hope everyone else having successful evening – radio, visual, photo or video.

I am picking up carrier but not meteors – what is going on? Should be loads as Geminids – also looking at RMOB most other Graves’ observers seem to have low counts.

Currently I am seeing between 120 and 130 echoes per hour from the GB3MBA beacon here in NW Hampshire with plenty from the? Norman Lockyer Observatory too.

The Live stream is at? and of course it works by day and by night !

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.

Re: Geminids

 

Hi Alan

There is a forum specifically for Spectrum Lab that might be able to offer you more help:?/g/SpectrumLabUsers
I have used Spectrum Lab for looking at pings from Graves, or the new meteor beacon, and have run scripts which just about work, though aircraft reflections are a killer.
I can't quite see what is your problem from the error screen you attached, and am not an expert on Spectrum Lab. It's probably to do with getting sample rates all sorted out, so probably best to list your settings and send them to the above group.

Hi Folks,

I have now completed setting up live streaming of all my projects at Lichfield Radio Observatory – these can be access via or

?

The live streams include:

  • Magnetometer
  • Meteor radio scatter detection from Graves on 143.050 MHz.
  • UKRAA VLF Receiver @ 23.4KHz – Brahms.
  • SuperSID Receiver (broadband multi-station detection of SIDs but with less amplification and reduced signal:noise ratio compared to the SuperSID receiver).
  • UKRAA version of CosmicWatch Muon Detector – this is master/slave pair.

Excellent correlations. I can see I'll have to watch for longer.

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.

Yes, I did see that jump in signal strength which I initually thought was a reciever fault.?

I'll relabel my graphs..?

The Crowd funder site has recently released a YouTube video with an interview with the designer. It's a bit basic in places, but it's interesting to see the design process he went through. You can ignore the first 9 mins or so.?

Hello,

??? ??? I have seen a similar problem trying to separate 23.4kHz and 24kHz with that receiver. Adjusting the Q too high can cause it to oscillate, but that is easy to avoid. Having the frame aerial with two opposite directions of sensitivity does not help. I have not tried 22.6, but I suspect it might be in the opposite direction to 22.1.

I use SpectrumLab with a b/w of 150Hz for each freq that I monitor and the spectrum plot still

It would be interesting to see if you trace for 24th November shows the sudden increase that I saw

on 22.1kHz, then that would prove that you are actually monitoring Skelton.
