    What previous attendees had to say about their experience

    "Just wanting to pass on how happy I am with the workshop. My background is in IT but I’ve been leading a team of radio/satcomms techs for a couple of years. I’ve picked up a little knowledge on the job but it’s so helpful to start gaining an understanding of the underlying concepts and fundamentals. The structure, content and delivery are great. Many thanks to all involved!" “Overall very happy, I learnt some things I didn't know and it gave me a better overall understanding and knowledge of Radio Communications."

    “Nice refresher course and some additional knowledge that I didn't know before.”

    “Overall, good course content for an introduction to radio communications. Covers a lot of components at a high level and their relationships to each other. Very fast paced so you need to be very switched on.”

    “Very positive, have a better understanding of some of the terminology and how the different systems work.”

    “So grateful that you ran this course, I have been looking for something like this since I started in a comms team lead role 2.5 years ago. There is no introductory comms training out there. It has already improved my understanding of my role and given me an even greater appreciation of my team of techs.”

    “Good course, well-paced and well delivered.” “Well presented, great knowledge from facilitator.”
