For those waiting for something new, RTLSDR blog has announced the new V4 receiver.
It’s interesting to see what has changed (and why) as well as what has not changed.
I won’t list the details, but a very brief summery is that it’s a better general coverage receiver, but for ADSB, the V3 is still probably better.
Fortunately the V4 isn’t a replacement for the V3 as they are both continue to be available.
thanks for the heads-up, you are right, it doesn’t look like it is an improvement for ADS-B when reading the description.
This isn’t something I’d use for ADS-B. It’s too generic.
I think I know what you mean, but the same can be said for the V3.
Once the V3 is coupled to its complementary filter/amp, it’s way above average.
I got one of these (Nooelec RTL-SDR v5 SDR) for something unrelated to ADSB. Should it perform better than a trusty FA dongle? I have a blue dongle in my station now and seems to work well but like everyone - always looking to improve numbers. I do have an FA filter that could be fitted to as well.
True, very true.
I got sent one of the SAWBIRD ADSB LNA’s from Nooelec. I’ve not tried it yet but there is a production issue on the screen print.
It has lower sensitivity at 1090MHz than the V3:
But it has way better rejection of out of band signals:
I’d be interested to see how it performs since this it the first non R820/R860 dongle that’s been available for a while. It might be a good option if there are strong out of band signals which would normally need heavily filtering and you don’t want to go to the extra cost of a filter/lna.
