I want to run a temporary 4m WebSDR. The software comes from PA3FWM and there is a binary for raspberry pie computers. The binary can run on any ARM CPU. I purchased a Odroid U3 which has a lot more CPU power. The picture shows the Odroid as well as the rtlsdr connected and a wifi stick used for connecting to my network. Running the WebSDR with 1MHz bandwith gives about 50% CPU load.
The board runs Lubuntu 14.04.2. I did not measure the current consumption on the 5V supply.
My aim is to put it in a box to the balkony.
Today i heard my first station on 4m with that setup. SV2JAO.
Saturday evening there were strong scatterpoints west and northwest of Berlin. Since the same time there was the July V/U/SHF contest this gave amazing scatters from the contest participants. I listened with our local 10GHz websdr and did some recordings and screenshots. Please see below…
