News and Information

Radio System Design Ltd
offers a wide range of consultancy services

The introductory Lecture course have been expanded to 5 days to cover aspects that have been requested, but not possible to cover in the earlier 3 day format. A second advanced course over 3 days is also now available, covering aspects of the digital hardware revolution that is radically changing the traditional view of radio systems.

Latest course development are a "Hands on Software Defined Radio" course, using a low cost SDR platform and either a Raspberry Pi or other common computer platform.  For more information or request specific details e-mail
