Bilstein,
Re your link. Now that's dedication to 'duty.'
.... who was it that said radar codes are meaningless? (and that's in no way aimed at you btw).

How bizzar I can now pick up aircraft on the ground at Christchurch from my receiver here at Westerfield. Noticed some the other day down to 50ft. Nothing has changed at my end perhaps someone has cut down a row of trees closer to airport. Also there appears to be another FR24 receiver in Chch F-NZCH4Last edited by Westone; 2015-05-04, 01:31.

I've noticed similar variabilities here in SYD although I can't pick up the airport itself from my location. I've been able to put it down to the removal of trees also (and other obstacles) but the weather seems to play its part, just as it does the scanner with analogue signals. The latter not necessarily being something I'd have associated with digital 1090MHz.

Having a standard means all other places and ATC know an altitude of the plane that is relative to all other traffic.
Only a brief description while walking home, so if I said something incorrect or someone wants to expand go for it.

NZ ADS-B feeder
Hi guys
I've recently got an SDR dongle feeding data from flights around me up to the web. I'm using a 6dB WIMO antenna with a RTL2832 USB dongle with gain currently set to 10.
The reach isn't as far as I'd like and I was wondering if I should get a preamp too? They do one here wimo.com/download/as-1090-deutsch.pdf
Can anyone suggest if this is the right course of action?
Cheers
Mike

What range does the WiMO cover? you may find its only 1-2dB at the required 1090mhz
You can get surprising gain from a DIY colinear or simple omni before going the amp route. I made one from a welding rod and some plans online and it was quite capable of 140nm
Afterall, pre-amp of noise is just more noisePosts not to be taken as official support representation - Just a helpful uploader who tinkers
