Just wondering, looks like it has the stereo encoder on one side and the compressor on the other, the trim pots for ajusting on the right, just make sure the left are the same as the right I suppose, I have stereo tool set up do still wonder.

The first one looks to be the PIRA coder and limiter in one board.
The second one from Radiomaster looks like a new development he made. It has a DSP chip on it, probably some ADAU... from Analog Devices doing the processing. Hard to tell from the video. We would need a direct audio sample and have a look at the modulation spectrum and waveform, and fm deviation statistics to tell if it's doing a good job.

I did see some stereo encoder compressor limiter things on ebay, considered getting one just mess about with, since it is a pain trying to build your own without getting clashing symbols, not just pre emp circuits, its the 15khz filters too, it becomes a nightmare.
Sounds like you need something from a garden center to get rid of the 15khz frequencies called a gyrator too.
