You will be chasing the signal over a few hours. The drift will put the signal out of range of the bandwidth every hour or so. Having nothing to compare it with makes it a bit hard, but the short of it is that its not really stable enough. If you find something that fits the bill, let me know. You want something with low frequency drift, something that is temperature stabilized would help as well. If I was going to do it again, I would go a 6 to 9 foot dish, anything bigger and the pointing accuracy is going to be a ‘problem’ and not worth the extra signal strength. You can (apparently) get by with a 4 foot dish, but I did not want to be scrapping around in the noise, so opted for a 6 foot dish, the wife was not so excited, so we both compromised and went for a 5 foot dish. It could be, but if you are reading this, you probably have hit some snags.Īlso, if you are reading this, you probably have an idea of what you are trying to do, so I will skip the intro and go straight to how I did it.Īnd just to be clear, we are talking about ADS-C, not ADSB, but it looks so similar that many (me included) often get it mixed up. When you write it down, in one sentence, its really very simple Ħ′ dish -> PLL LNA -> 18v DC pass-through PSU -> RTL-SDR -> SDR# -> Jaero -> VRS.Īnd with that signal path, you will have planes on a map.
