Listening to 10GHz Rain Scatter in Esslingen using a LNB
Today I was able to receive multiple 10GHz beacons via Rain Scatter thanks to a small thunderstorm crossing my hometown.
As I’m living in a deep valley this band is normally pretty much white noise.
What a great chance to test my new LNB!
Setup
Some equipment from my electronic dumpster:
- Bullseye LNB (Naked! no Dish!)
- Bias-T injector
- RTLSDR
- 14.6V DC power supply normally used for charging my LiFePo4s
A picture of this overly professional setup.
The Signals
During peak storm the band looked like this.
The Bullseye LNB is well known to have a stable internal clock source. So no drifting issues can be seen. But there’s still some static offset which must be compensated. To get the final frequency an offset of +9750MHz must be added (618MHz + 9750MHz = 10368MHz, the beacon band).
When listening to following recordings you immediately will recognize the broad, scattered CW signals.
- 10.368.802G, DB0UL, JN48XK, Unknown, ~66km -
- 10.368.810G, DB0ANU, JN59GG, 10 Watt, ~106km -
- 10.368.820G, DB0MOT, JO40FF, Unknown, ~173km -
- 10.368.850G, DB0GG, JN48NR, 1 Watt,~13km -
Many thanks to Achim (DD4AB) and Stefan (DL8SFZ) who helped decoding the CW signals by ear!
