Here's the latest one that popped up: Global SDR based TOA transmitter location

Wow! Thanks for that link!

First ADS-B, now this. Pretty soon we'll be tracking cop cars in real time.

The math had always been known. The technology that used to cost millions such that only the military had it now costs just a few bucks. And now coding skills are so ubiquitous that people write the code just for fun that would otherwise would have cost a million dollars in man hours to develop.

It's an amazing world we live in.

The locating ability is cool, but I'm glad to see there's an off the shelf solution that offers full HF band monitoring (if I read correctly, and not just a tiny slice like many webSDRs).

Sssssh! If you remember one of my other SDR threads, you might know my application.
Funny thing, when all you're looking for is the presence of a signal, encryption really doesn't matter much. It does give lots of
nice transitions to determine time differences, though.

It really is crazy how much the tech has advanced. All the open-source libraries makes a lot of this stuff a fun weekend
project.

The fast lane version of DSD+ has a LRRP mapping program that extracts the gps positions for transmission and maps them for you. There are a couple train systems back east that use it and it’s cool to watch how accurate it is.

Seek were you the one that made the close call monitor?

Yep, that was me. It's evolved some -- one key improvement is adding some pretty strong attenuators into the mix and using more than one RTL-SDR.
