Sepura portables - NOT amateur radio

For almost 17 years now I have been retired.  Work seems a very long time in the past. In my professional life I was a project manager at Sepura involved in the design of TETRA portables, widely used in public safety.

It would appear many generations of products have been designed and sold since I left. For example the SC20 portable has sold 500000 units.
