All that is necessary is that he knows it. correct, and i do, as well as the barometric pressure, which also matters. What he's manifestly failed to do is say how he knows the altitude of the aircraft he's seen are 1700' to 2000' above him. I agree that he is too often sparse with support for anything he says but on this occasion he has described how he knows in another post. See his Message-ID: Elsewhere he has said he has the necessary gear. my posts are not intended to be highly detailed instructional articles on how to do something.

In article , Alan Browne wrote: There are such receivers for ADS-B. They run about $500 or so (maybe cheaper now). There were no transponder receivers (for older traditional (pre-ADS-B) transponders that I know of other than test equipment or actual decoding gear in the ATC radar receiver shed. Even if you had such it would tell you quite little as you would not know the range/bearing from the radar that ping'd it (or from you). You would get a transponder code and optionally altitude (and some other stuff that isn't especially relevant). |

wrote: nospam: no it definitely doesn't. *you* knowing my elevation doesn't change anything. you're arguing just to argue. Not at all. You talk about 1700 or 2000' w/o specifying whether that was AGL or ASL. Quite important, wot. But he did: nospam 05/28/2016 "where i live, small planes often fly over houses at around 2000 feet (the lowest i've seen is 1700 feet)." nospam: it' not ambiguous at all. it's clear that it's agl. why would i say a plane is 2000' msl over my house? that makes no sense. What altitude was it? Recall that the issue was how high above someone's house, and you blurted out your observation of 1700' or 2000' w/o specifying AGL or ASL. Of course you should be clear if only for clarity's sake. Why, though? The topic was privacy invasion, not clear altitude reporting. He made it clear after Andreas did his best to argue that he was indeed in reference to AGL. Alan Browne: BS alarm. nospam: your alarm is self-triggering. Not at all. Yes these devices are used by those w/o the means for better equipment. There's just one little fly in the ointment you've provided but you're too ignorant to even know what it is. Also, it appears to be something you cannot express either. nospam: yes it was mentioned yesterday. What you've never clarified is what the 1700' or 2000' is relative to: AGL or ASL. Yeah, he did. Read the entire part of converting ASL to AGL nospam: wrong. what's clear is that you can't admit that you don't know something. No what is not clear is anything you've said. It does not and cannot add up. Which says more about the bullying and witch hunt you guys are doing than what nospam is actually saying. Nospam can be a complete asshole and can never admit to being incorrect. But the bullying you're doing here is not over something he is supposedly incorrect about - just that he has been "unclear" and you have failed to understand something. Same with Andreas. Here's a tip for you, if you wonder about something - ask! Here's how this "conversation" should have gone: nospam: planes sometimes fly at 2,000 or 1,700 feet above my house Andreas: How do you know that exactly? nospam: I see it on my radar Andreas: But that's ASL nospam: yes, but it's easily converted. Andreas: Oh, ok. -- Sandman |

Andreas: Oh, ok. pretty much, although there is no radar used at all. it's simply a radio that receives signals from the plane's transponder. |

So how are you getting the altitude data? Do you own an ADS-B receiver? not yet, but it's on the list. as i mentioned yesterday (which you clearly missed), i have a receiver for transponder responses that decodes them and displays altitude. And there are apps and programs like PlaneFinder, https://planefinder.net. Looks like I missed all the fun... |

What he's manifestly failed to do is say how he knows the altitude of the aircraft he's seen are 1700' to 2000' above him. Respectfully submitted, you must have missed one of his posts. In one of his posts, maybe the third or fourth round, he mentioned that he has a radio receiver that can pick up the transmitted data from the plane. I'm not an expert in aviation, so I don't know if such data exists, or if such a receiver exists. But it would have saved a lot of time and bandwidth if he had mentioned possession of such a receiver when he first mentioned the altitudes of planes in his home area. Such as "I've seen airplanes over my neighborhood at 2000 feet and as low as 1700 feet, based on flight data from my ACME model ABC555 flight data radio receiver." But it would have been SO boring for his nature of baiting the hook! |

No for you to prove you actually didn't just discover it in a desperate attempt to prove your very weak story. You know - not knowing the difference between ASL and AGL and that a/c routinely operate at 1000' AGL over built up areas. i'll post a photo of what i have on the condition that you'll admit you were wrong, that you didn't know about such devices and also to stop arguing with every post i make. deal? I happily admit that I didn't know about the particular sort of device you claim to have for non-ADS-B reception. It's a bit of a low cost, band-aid passive solution, but could be useful in congested areas for someone who can't afford a proper ADS-B system. Here's the proof you should: 1. Video, from your house (backyard or whatever), in operation, reporting on an aircraft nearby, its altitude. 2. When you're ready to do your video, you send me a mail message. I will return a phrase to you that you will print up in a large font and include in the video with the device operating. You will have 2 hours from then to make and post the video. For further detail, write me at my address above. No freelunch. Specify the day and time period that would best suit you. 3. I'll always point out when you're wrong. That is usenet. And you are so often wrong. (eg: about the a/c at 1700' and 2000' reports that you implied were above ground level). Be clear - don't say HS like "already said" 'cause you've actually said nothing at all. actually, i've said quite a bit, but you're so intent on arguing to pay attention to any of it. I'm ROTFL lauging at what lengths you've gone to defend the indefensible.

I didn't say they didn't exist, I mentioned what I knew to exist. I'm delighted there are these products now which we didn't have when I was active as a pilot. now that you've been shown to be wrong, you come up with some mysterious issue that you refuse to articulate. I'll back off on that one ... slightly. While the device will give you the transmitted altitude from the other aircraft, you won't have other information such as direction to the other a/c from where you are. That is the fly in that ointment I was referring to. But for the life of me I don't know why one would waste money on such a thing if he wasn't an aircraft owner. FlightRadar24 gives you much, much more for much, much less. -- She hummed to herself because she was an unrivaled botcher of lyrics. -Nick (Gone Girl), Gillian Flynn. |

Agreed. However, as I mentioned above there are easy and free ways to get id., airspeed and altitude of aircraft flying overhead...
