Radio meteor detection - Lyrids

Post by JochenM »

Lyrids results from my radio meteor detection station. Results largely align with what Rainer and Stu observed.

I don't think I have :)

Basically, the setup I have contains:

- A yagi antenna set up in the attic.
- RTL-SDR dongle (I have the Nooelec R820T2).
- Old Windows 10 laptop.

For starters, the transmitter I'm using to pick up the forward meteor scatter is the popular GRAVES radar in Southern France (143.050Mhz). I tested several others, but this one gave me the best results.

Setup-wise, I opted for a 4-element yagi antenna, tuned to 140 - 160 Mhz; so pretty much ideal for what I'm trying to do. I couldn't be bothered to completely build one myself; so I just bought a kit that only needed to be put together (took 20 minutes or so). It's sitting in the attic on some of those supports used to for example paint a door; not sure what those are called in English (trestles?). The antenna is connected to the RTL-SDR dongle which is plugged into an old Windows 10 laptop that sits on a small table in the attic. Software-wise, I'm using SDRSharp to control the RTL-SDR receiver and Spectrum Lab to analyze and capture the data (so pretty much the default setup if you will). The only slight addition I made was in how the system is managed. I didn't want to have to go up to the attic every so often to check on the system (it's accessible by one of those retractable ladder hatch thingies, which is annoying to go up); so I made it completely "hands off". Essentially, the laptop is wirelessly connected to my home network so I can remote desktop into it if need be. The data that's being gathered is automatically being copied to a NAS in the home network as well. It all seems to work pretty well; haven't been up there for nearly 2 months now.

The only thing that I'll have to keep an eye on is the temperature of the rig during the summer months (it gets toasty up there during hot summer days), but we'll see how that goes :)

Hi Jochen,

Great. Are you going to upload your data in rmob.org ?

I've tested the upload function in Colorgramme a while back; but couldn't get it to work reliably (that entire piece of software is not exactly fantastic). Is there any other way to upload (be it through software or manually)?

Hi Jochen,

For my friend and me it works without a problem.

You need to run it in Windows XP SP3 compatibility mode. This is nowhere explained ... That is all ... Many have the same problem and from to time the questions arises in the RMOB facebook page :lol:

Are you using Spectrum Lab ? If yes the file to use with Colorgramme is located in the folder of Spectrum and is named RMOB-YYYYMM.DAT ...

The only problem I have is when starting a new month day 1 it telle me that the is " Introuvable " but then I just exit Colorgramme and start it again choosing the corresponding month file ...
... (that entire piece of software is not exactly fantastic) ...
I understand as it was written by a French guy ... :lol: :lol: :lol: Just kidding ...
