VRT and VITA 49 — a video and discussion about Radio Transport Protocol Objectives, Overview, and Ap

The reason I posted it is because our Flex ecosystem uses Vita 49 (.0?) and the video and PDF are now talking about .2. It was also interesting to hear him talking about how important it was for .2 to incorporate the .0 API. It had echoes to me of the recent Flex upgrades to its API. I’m imaging a long term project that allows Flex users anywhere to share receivers and transmitters among themselves globally. Want to work Europe the easy way? Use the Vita 49.2 protocols to find an available transmitter somewhere near the grid that you are looking for and give a call.

I came across this "Software-Defined Radio Handbook: 12th Edition" from August 2016 by Rodger Hosking (who I have mentioned in this thread previously.) The opening Preface is provided below. The handbook contains well written (and largely comprehensible) information that (I strongly suspect) forms the engineering underpinnings of the 6xxx Radio Servers from Flex. And since this is from a public source I wanted to share it with all of you.

Quoting, "SDR (Software-Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing.

This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace legacy analog receiver and transmitter designs while offering significant benefits in performance, density and cost.

In order to fully appreciate the benefits of SDR, conventional analog receiver and transmitter systems will be compared to their digital counterparts, highlighting similarities and differences.

The inner workings of the SDR will be explored with an in-depth description of the internal structure and the devices used. Finally, some actual board- and system-level implementations and available off-the-shelf SDR products and applications based on such products will be presented."

Your continued comments and insights are welcomed here in this thread. And... I'm tagging @Tim - W4TME ;-)

@Lasse SM5GLC VITA 49.0 is what is implemented in the Flex architecture. I'm interested in seeing what it would take to get everyone to VITA 49.2.

Thanks for your Youtube video reference!
