Hello
so I jump into this topic because Im also trying to get my system up and running. So far the hardware and software are working together, at the beginning I had my antenna pointed at the graves receiver and not the transmitter but I sorted that out too.
Hardware side the system looks like this:
9 element 144 MHz antenna at about 4-5 m height
Elad S2 receiver or Winradio G313e ( the colibriDDC that I also have isnt that good at higher frequencies as stated - it receives AM signals in 140 MHz area and FM station at 150 MHz). The first two are somehow the same only the Winradio seems to have a little lower noise floor as the Elad.
Until everything is running fine and Im sure that is will stay so - the antenna is connected to receiver using about 6-7 m of RG-6 cable from fair good quality, later I plan to use the ecoflex 15 that I have for this purpose and maybe also some lna to compensate for the cable.
Attached a screenshot done just a half an hour ago with so signal that it looks like some kind of space junk, it not looking like the standard radio signal that meteors are producing.
Time is local time for Austria, distance to Graves transmitter is about 850 Km east from it, center frequency 143.048.400 bandwidth 3KHz.
So if someone can identify what it was captured at that time I will be really thankful.
All the best and clear skies
Emil
P.S. My plan is to activate the all sky camera that I already have (running on a Asus Tinkerboard) but I have to redesign the housing (3D Printer already at home and ready to "fire") and combine the radio signals with the night images.
