It is a pity the noise value is not there any more. A handy thing to let you know if you have some issues that might require a filter. Well I re imaged my new SD cards after they arrived today. The ones that will stay with the PI4’s. All set up and happy with settings and set up.
From refreshing myself with Joe’s great insights with his graphs, my settings, as is, just from installing the Airspy script and no tweaks, gain at 21 of both PI 4’s, is pretty good. Working off the basis of:
Mean Level - The mean level of signal strength. The higher the number, the better (i.e. -20 is better than -23.2 in this example).
Peak Level - The best signal strength you were able to attain during that defined period of time graphed. The closer to 0 that number is, the better.
A little while ago, I decided, in best interests, to drop the height of my antenna mast. Although well guyed and no previous scary moments in storms, I was willing to maybe possible loose some detection range, for the sake of not worrying about what was happening on the roof, during a storm.
First the both rigs are showing a Peak Level of 0.0 which I find a bit dubious. With the current version, over 8 hours, on my A rig, strongest gain antenna and I am taking the Mean Median Level to be a average of you mean level, -1.3. My B rig, on the weaker gain antenna, the Mean Median Level at -5.0. According to Joe’s instructions, pretty good. But the litmus test, watching the tracking live. I live about 450 kilometres north west of Sydney Australia. I have great North to South West coverage. Tracking flights from Asia and they approach Sydney, over Queensland, all the way to they start their finals, dropping into the Sydney basin. Same for traffic heading North East from Southern Australia towards Brisbane. We are on the Western slopes of Australia’s Great Dividing Range, similar to the US’s Rockies, but not as high. My easterly coverage is a down due the sandstone wall, but I can track up the eastern coast traffic heading for Brisbane from Sydney, when they hit their cruising heights. Here is the clincher with the current setup. I can track US traffic as they approach Sydney from the NE, also traffic coming from New Zealand, heading for destinations west of Sydney, at their cruising altitude. I have never tracked flights from Melbourne heading for the US as they cruise past Sydney. With my strongest antenna and my current settings, I am now tracking these flights. Such is the benefit of the development of the PI’s and the setups supplied from this site. Happy camper.
