Re: Replace vehicle radio with rPi and RTL-SDR?

A vehicle radio has lots of front-end filtering (band-pass for the broadcast spectrum of interest) and shielding (from vehicle generated RFI and power-bus noise). Adding all that to a rPi + RTL-SDR would likely be required to get a decent signal. A cheap FM tuner hat for the rPI might be another pot...

Re: anyone done a comparison with the flights aware pro stic

I have one of each. The FlightAware USB dongles have a front-end RF amplifier (LNA) built-in, which increases their sensitivity (thus range), but also how easily they can get overloaded by any other nearby RF signals. I can see that in some of my waterfall plots. So it's recommended that you use the...

Nice any plans to put your app on the iOS store? I've been working with at least one other developer who is...

For my networked personal computer, I'm running a Raspberry Pi 3 with an RTL-SDR V.3 dongle. The Pi is near my antenna, and streaming IQ data using rtl_tcp over WiFi to my Mac and iPad down at the other end of the house. Depending on WiFi interference in the neighborhood (quite a lot), the signal do...
