Did you maybe write down more details somewhere else? Also, consider sending your article to the https://www.rtl-sdr.com/ blog, it is really cool work!
Thanks! I have notes scattered around, but they're not coherent (unlike the RTLs! <rimshot>) and I doubt I'll have time to publish them as once I've written an article I generally have to move on the next thing, which is the downside of being allowed to play with nice toys.
