Title: Flight number discrepancies
Post by: orinoco on March 31, 2022, 09:56:12 AM
I feed into other sites as no doubt many of yourselves do. I am seeing big dicrepancies on my radarbox map in comparison to all the other sites as below

Site 1.5 miles from me that tracks about the same numbers as me but on radarbox

I have contacted support but they have said my stats look fine not to worry about it, any input/pointers or advice greatly appreciated

Could be something as simple as the time outs each tracker uses for when the aircraft signal is lost

Thanks for the input Alan is there anyway I can change this at my end? Seems strange that the 97 is not a peak and was a fairly constant number on other apps including VRS that I setup to check the numbers, on list checking on VRS against the site 1.5 miles away teh aircraft were the same so it appears hsi site is not timing out on the same aircraft

Have you tried adjusting the gain

I have tried adjusting the gain, whatver gain setting I have - Radarbox tracks 40-50 aircraft less - virtual radar using beast mode same port (setup after radarbox to check figures) shows consistently 40-50 more airctaft as do all the others, adsbx, piaware - so completely stumped at this point

Do you change the gain on the Radarbox set up alone or generally, Great coverage, where are the missing aircraft close to you, at a distance or what

Always adjusted the gain in dump1090 config file, as thought that in beast mode with port, radarbox was just pulling a data dump of the infromation received in dump1090, it varies AA off the coast of Ireland 120nm had a message count of 5200 messages but not seen in Radarbox, was seen in all the other softwares and Virtual Radar and on teh radarbox site down the road.

No idea on what you state there, I would need to leave that to someone with suitable knowledge
