  1. Very nice totals, that's for sure. Mine were around 50+ at the maximum, and the difference in distance between us and the source of the signal shows itself perfectly here.
  2. Hello @strinjf and welcome to the dark side of capturing meteor echoes with a Pi Nice L shaped echo you got there! There are some ways to do it, better with the new RasPi 4, but nothing with SpectrumLab, I'm afraid. The software architecture was not made for that, unfortunately, so you have to resort to alternatives, if you want to use a Pi. This https://sourceforge.net/projects/echoes/ is a project for which I gave some feedback with a Raspi 3b+ some time ago. The Echoes code works with a Pi, with a couple of tricks along the way, but it does not present the same volume of customisation that SpectrumLab has. Nonetheless, it could be good as a start if you want to 'play' a bit with it. Regarding a PC instead, you don't need much, except if you want to stream your live waterfall online, and even an old computer will work. If you need anything else, please feel free to ask.
  3. Hello @jarralad58, Ken, Could you expand the conditional actions windows as much as possible and take another screenshot? I am using a similar setup to the MetScat v7, but I never saw that particular line becoming red. Or, if you can, could you attach the associated text file for the same setup? So we can check it better.
  4. That sporadic E was surely well defined, nice catch @johnb! I got something similar in May, I think, I should check my archives. Thank you for sharing my stream @SteveNickolls! Let's see how different the two will be.
  5. Yes, I think I got those two peaks at the end of July, as the completed monthly data shows: Regarding the negative declination, non necessarily, since the declination and the right ascension are not tilted in the same way of azimuth and elevation. The RA and Dec grid is aligned with the celestial equator (which is the projection of our equator into space) with the North Celestial Pole being near the Polaris in UMi. The azimuth and elevation grid instead is purely local, so it is possible to see negative declinations from here: the star Spica, half of Orion constellation and the whole Aquarius are in negative declinations, to give some examples. The background values have risen, with peaks around 20/30 meteors per hour, which is similar to what happened last year in the first days of August. Sign that we are already inside the Perseid stream. Curious to this year's maximum! Honestly, they surprise me too. In the first place I didn't imagine that I would be able to receive the GRAVES signal from up here, since the volume of sky that we share is definitely low on the horizon. But yes, having an unobstructed view towards the South definitely helps a lot. My antenna points almost towards the ground, more or less.
  6. Hello @Geminids, this is the updated count for July, up to today's midday. Very interesting totals ramping up in the last days, 400 meteors yesterday is the provisional season maximum, with over 40 meteors/h peaks in the mornings.
  7. Yes, I bought some of those afterwards, but while they did something good, the interference from my main pc sometimes still appears. Well, as of now nothing that I can do about it, since I cannot locate the hardware in a different place.
  8. Thank you! It was indeed one of the strongest I managed to register. Orbit is limited, indeed, and from here we are near those very limits. However, it is doable, so I will continue to monitor. Regarding the ISS and the Starlink Trains, I got four more transits of the first, and one of the 7th series, but I need to start drawing everything on a map properly, otherwise all of this will not be very precise.
  9. Thank you! I wanted to go for the stream since almost the start, and now it is happening! Waiting for the Perseids later in the month... and then in August. Yes, as you surmised, my zero (GRAVES) Doppler is on 1060/1065 Hz on SpectrumLab. Maybe I should add a marker of some kind to make it more clear, thanks for the suggestion. Had to jostle a bit with the positioning of the antenna cable indoor, since sometimes it still picks up noise from my home pc...
  10. I managed to combine a slider on the static image of the last L-shaped meteor echo received from my station together with the actual echo sound recording. It was a step I wanted to do for some time. Now you can 'hear' and 'see' it both at the same time, and even if I'm not listening every minute, I can recreate the event. I have also put my SpectrumLab screen on live streaming on youtube, you can find it here: hebweather.net/meteor-echoes/ Again, thanks to everyone here on the forum who helped me in reaching this point!
  11. Hello @Geminids, I'm really sorry for the super late reply. I had lost access and only now was able to remember what email I had used. In any case, I continued recording what ISS transits I could, and also many of the new megaconstellation Starlink passages of the earlier launches. I still have to compile a map like the one I posted here (hoping that I can go that far back on heavens-above, which I use to get the satellite data on the world map) and I hope that my MRes will leave me a bit of time to do it. I managed to get this one from yesterday's passage, one of the best ISS echoes I've ever captured, but it was further South compared to the ones of that map. Only think I can say for now, is that the study continues.
  12. I really like the second one, with the complex echo. It's interesting that we got different signals for that day, I checked my archive where I usually store the strongest ones, but I didn't keep those, meaning that there were not on my spectrum. Very interesting. I got this big one however in the early hours of the 11th, one of the most beautiful of the month for now.
  13. Thank you very much @BiggarDigger! That post was a goldmine of information, I've already found what I needed, so thank you again! ISS again this morning, today with a more westward track, but I got an echo. As you can see, the track is very faint, but it is visible from approximately 10:32:40 to 10:33:00 BST, just at the edge of my 10 degrees visibility circle from Stornoway. Combining all my three observations (red ticks for start/end echo times) into a single map from Dijon perspective, we get this approx. shape, which is mostly into the GRAVES radar main lobe, but also (especially with today's transit) above it. Further transits are definitely required, but I think that it's already possible to get an idea from this.
  14. This afternoon's update about the ISS. I managed to get this transit too, from around 11:21:55 to 11:22:15 BST approximately. The signal was fainter than yesterday, in fact the algorithm didn't manage to recognize it as a meteor and didn't capture it, but I clearly saw the oblique line on the screen, along with the frequency shift. The area remains the same, I think that with this we are possibly at the northern limits of the main GRAVES Radar area. Will continue to check in the next days, but now I'm pretty sure that this is the ISS. Still no echoes from the Channel or southern England transits, will have to wait for pure northern France (like Normandy) ones to see if it's possible to get something from those locations.
  15. Thank you for the reference with the CEST timezone for Dijon and the details on the frequency behavior, it definitely looks like what you said. The ISS was above my horizon, albeit very low in the daytime sky, but there should be no doubts about that. I'm monitoring this morning, but for now the two higher transits (one on SE England and one on the Channel) were not seen by my station. Waiting for the third one which should approximately follow the orbit that gave me yesterday's signal echo, just a bit more towards the north, but approaching the GRAVES main lobe in the same way. Crossed fingers! Still waiting for those transits, but I'm monitoring the waterfall all the same. I lowered a bit the detection treshold so even if the pass is faint it should be able to capture it. Speaking of captures, that was a fantastic echo! Very big and much more detailed than what I managed to capture the other day. The frequency shift is clear as a day, and you're right, if that was a night time even it would have been very interesting to see, possibly even approaching fireballs brightness if the mass was around what we are talking about. I noticed that you have seconds in your detection text, together with a buch of nice info. Would it be possible to take a look at your conditional actions to see what needs to be done to obtain that, or if there is an online reference that I've not managed to find, could you please point it to me? Thank you! P.s. Got another big one last nigth, always fascinating!
