inspired by OM DJ0MY (thanks!) I tried to get some nice doppler signals. I tuned to Graves radar on 143.050 MHz and Hamburg ATIS on 123.125 MHz.
With my "new" diy lindenblaad type antenna (new == 1,5 years old ;) ) for 70cm I caught a few nice doppler signals.
Let's go :) .
|Doppler by planes on Hamburg ATIS frequency. The transmitter should be about 120km away.|
|Frequency drift of RTLSDR, maybe.|
|Distance between QTH and Hamburg ATIS transmitter.|
|Doppler by ISS on Graves radar frequency 143.050MHz. See pulse/pulse break on ISS. ISS was about 1000km away - or more...|
|Pulse break from Graves radar on ISS.|
|Pulse length from Graves radar on ISS.|
