Quadrantid Meteor Data from the UK-UPDATED
Complimentary to Rainer's data, here are mine from the UK.
The Quadrantids are debris from Comet 2003 EH1. I was surprised by the brevity of this shower, which only lasted a day although the counts would suggest it was intense with up to 160 counts per hour (on my system).
Next up will be the Lyrids in April, although by all accounts the hourly rate generally is relatively low for this event. We'll see.
Thanks for looking.

Re: Quadrantid Meteor Data from the UK
Excellent data Stuart
You always seem to get a third less counts than Rainer, is it by chance that as the Earth rotates Rainer hits the major peak after you. Maybe one day you will get more than him as you hit the peak and as the Earth rotates to his side the peak is missed during his night?

Hi Stu,
Great and yes it was a short show.

Hi,
Here is a nice page to see what is going on with the Showers ...

That’s a possibility, but Rainer also has more transmitters on the same frequency within range than I do (mine is only one in France), so I think his system may be able to detect more meteors because there’s more chance of receiving a detectable reflection from a greater spread over the sky, hence a larger count.

Re: Quadrantid Meteor Data from the UK
Very good Stu! Interesting to see the data.
Forgive me if a silly question (I don't know anything about it!) - the graph shows the number of 'counts / pings' that you get, is there variation in intensity / magnitude of the returns? If so what does this tell us?

Not silly at all. The system does actually record the intensity (and duration) of the pings, which do vary quite a bit, and I’m sure there’s a lot of useful scientific data there relating to how the burning meteor trail interacts with the transmitted signal. The size of the meteor and it’s speed and trajectory no doubt play a role. This is something I was planning to take a look at. I’m sure there will be plenty of technical papers available on this very subject.
Cheers

Interesting. I guess the stations here in my Town Zapata and Ehlert when there is a big meteor shower detect the tinier meteors too but when we look at a normal meteor shower or perhaps daily dust fall onto the eaerth it is not that different.
Look at the image below ans focus on the RMO station Nelson, Zapata and Ehlert with nearly very same values on the highest hour. Nelson is just reading one Station TV RF channel 2 which is 54.31 MHZ (Reno, Nevada, USA ?) and we are reading many TV channels RF channel 7 which is 174.31 MHz. So I guess we have an advantage due to so many stations when very small meteor fall and also I am away from RFI in the town as I am higher. I do not know where Nelson is located e.g. is he is in a town or up on a Hill like me.
There are 9 stations in USA transmitting on RF 54 MHz and the strongest one is in Reno, Nevada with 27.7 kW transmitting power.
While in our case the strongest one is 185 kW and the weakest 26.7 kW (see attachment). There is a nice page where one can trace all transmitters in USA https://www.fcc.gov/media/television/tv-query
One more thing and I guess we are proofing that also at high frequencies meteor detection is possible. In many papers I have read that low frequencies are better but comparing the results of our two stations with the other stations using low frequency we have a good record of capturing meteor echos.
Not much differences and graphic curves are very similar too.

The software SpectrumLab writes you a text file each day over 24 hours and there you can see different values.
The vales are separated by a comma " , " and mean the following
1. Time HH:MM:SS
2. # of Echo (Starts new every hour)
3. Echo strength in dB
4. Surroundig noise in dB
5. Frequency of Echo measured against the scanned frequency
6. Duration of echo in cycles (one cycle is the time of refreshing the waterfall)

and there is one more monthly file made by Colorgramme software

Re: Quadrantid Meteor Data from the UK-UPDATED
For completion, here's the entire dataset for the month. The Quadrantids certainly stand out against the background sporadics
I don't think there will be much more activity until April.
Thanks for looking.
