I have started researching antennas and am looking at my first built antenna being a colineal coax using RG6 with a 16 element array. As you may have guessed from the name I ran raspberry pi's, I am reasonably competent with Linux operating systems having made the transition about 12 years ago and never looked back. I will probably post a few pics of planes at Brisbane airport also. As the ATC's say gedday.
    the supplied antenna that comes with the dongles isnt really optimized for adsb although it does work, i just trimmed mine down to the correct size but didnt notice much of a difference (am about 5km from YPAD)
    built myself the spider (non solder version) for under AUD$20, and stuck it to my old tripod and placed it on the carport roof, and it worked much better.

    going to attempt the colinier next, but for some reason avoided the coketenna and cantenna

    Well my coco is all taped up and in a conduit in the air just waiting until Monday when I can get some mcx connectors to plug it into the dongle. So what length did you cut the supplied antenna too ? I measured mine and calculated it to be a 1/4 wavelength.

    New feeder at Geelong Airport?

    Noticed today there is a new FR24 feeder with the code F-YGLG1. Victorian spotters might know differently but I don't think Geelong airport any longer exists and therefore YGLG is probably not a valid airport code. I guess it's not much different to T-YPOR1 for Portland which I think should be T-YPOD1. Anyway welcome and well done to the feeder who is hosting F-YGLG1.

    Interesting point, I imagine it is more about the location of the feeder as FR uses radar like codes, in reality FR could use numbers but the codes used for the feeders adds an element of interest.

    Is anyone else noticing a lot more aircraft traffic over the ocean area between NZ, New Caledonia and the east coast of Australia today? Routes that were previously dotted lines / estimated positions are now solid reports - with some tagged feeder IDs over 750nm from their 'home airport locations'. At first I thought a new feeder must have been activated on Norfolk Island, but a number of different feeder codes are being shown.

    Or has something new been added to FR24 ?

    Probably got proper satellite feed input now

    THat said, a recent statement pretty much blew the idea of aliases out of the water even more.

    If you know your database usage, this will make more sense.

    Stating there is a table array for displaying aircraft at any one time, produced live from all the different sources of data it's receiving. And it's not a single line record from any one supplier, but a mixture of the sources to make the array complete

    So the alias, is quite likely totally wrong/random/incorrect in 99% of the cases

    Delcomp spent years trying to talk me into manning a rowboat out in the Tasman. Perhaps he's managed to get one up and running before I could.

    Looks like Oblivian is correct and they've managed a sat feed and it's just hanging on to the last received (bogus?) alias. Thanks for the alert, hadn't noticed it.

    Perhaps they're tapping into acars position reports. Whatever the reason, the map looks a tad more professional.

    Regards,
    Gregg

    I see that its basic position information, groundspeed is probably being calculated which does suggest that its coming from a Sat feed.
    Certainly great coverage if its true.

    Looks a bit like a Glitch

    Nomad77,

    I think you're more correct re calculated positions than my assumptions as on watching the tracks they are straight just like the previous dotted lines and not following the expected great circle routes. I've flown across the Tasman in Flt Sim (I'll get my hand slapped for that piece of info) and it necessitates altering track frequently. One certainly doesn't fly straight lines.

    Perhaps some one simply forgot to add the dots to the calculated paths at FR24 HQ today. PAO856 (and other aircraft) is coming into SYD from Apia with the same track pattern we're seeing across to NZ.

    Having said all that, aircraft flying across the bite are showing the usual dotted track. So....

    Regards,
    Gregg
