    "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!"
