Listening 144 MHz beacons and Aircraft scatter
After the repair of my antenna system for 144 MHz I decided to do some search for beacons which I can copy.
I did this before but not very successful. Then I only heard PI7CIS which now is QRT
Now with some more time and using better reference I found several beacons which I can copy most of the time.
I was surprised by this good result and noticed that the ODX beacon F1ZXK was audible very often.
I never expected that Aircraft scatter would work very well on 144 MHz but by listening to F1ZXK I started to realize that this was aircraft scatter.
The scatter area seems to be in a major airway
I made a longer measurement using Dopplegram to see the different received signals from the beacon.
This is a 10 minutes registration, in this period we see at least 6 aircraft causing reflection
This is a registration of 70 minutes with many aircraft, you can also see the drift of my LO.
When there are no aircraft in the scatter circle I don't receive the beacon.
It is clear that aircraft scatter is also very important for 144 MHz.
