Apologies for the radio silence...

Oh ho ho yes! Is funny because this is a radio blog!

...I'm in the middle of a job transition/cross country move.

In the meantime here is an interesting, free textbook from Analog Devices on Software-Defined Radio for Engineers. I've been thumbing through it and there are some interesting sections on fundamentals that hobbyists (or engineers) who dive into applications of radio (Like GPS, ADS-B, or ham modes) might have missed or glossed over, like probability and time/carrier synchronization. 

Even better yet it comes with code and lecture materials. Direct link to pdf.

Blue Origin In-Flight Escape Test

Super proud "dad mode" on.

I work for Blue Origin. I had the honor and privilege of representing the company as one of the co-hosts for the live webcast. The full webcast is here, if the director's cut (below) gets your blood pumping you should definitely watch the entire flight.

I've spent the last four and a half years working on the propulsion modules' aerodynamics and integrated simulation. It's my baby. I'm glad to have her back from space after five successful missions, including a triggered in-flight escape. 

More cool footage: here's a frame-by-frame of the escape event:

While I enjoy playing with SDR in my free time - this is my passion. Gradatim Ferociter!
