I am located in Westerham, Kent and have a good view of the sky from the south-east to the west.
I just use a basic antenna for this with no LNA. It is in a horizontal configuration and positioned in the loft space, which may be why I tend to get a weaker signal. I have a couple of other types of antenna, located in better positions, that I use for other radio astronomy projects. One of which uses an LNA module for hydrogen line applications.
As far as non-meteor events are concerned, the software removes signals that don’t contain at least one frequency near an estimated reference-frequency, hopefully keeping the meteor echoes. Its, not perfect though. I will have to try any determine what percentage of signal are actually removed.
It’s good to have an opportunity to compare my results with other observations and recording methods.
I began running my set up in early 2019, concentrating on the major meteor showers. However, this year I have left it running full time.
For the recent Geminids I recorded just over 80 counts (raw data) for the peak on the 13th December (day#347), which I found to be at 20:00hrs. There was also some activity in the early hours of the 14th. Processing my data to reduce interference, reduced the peak count to 64. See images below.
I am recording my data using a Raspberry Pi 4B, running GQRX and python logging code, connected to a 3-element Yagi. I then process and plot the data using python on a laptop running Ubuntu Linux.
