The classes were shot by Robin Room M0RCR and are available on a set of 8 films to individuals and amateur radio clubs in order to support study towards the Intermediate examination.
Please note that these are not professionally produced video recordings and they have been copied from VHS originals so the picture is a little rough at times.
Although the classes taught were up to date at the time, these recordings are offered in good faith, and while they were believed to me a true reflection of the syllabus as it stood in 2003, there have been changes to the curriculum since then. Neither Steve Hartley G0FUW nor Paul Whatton G4DCV accept any responsibility for any incorrect information contained in the videos. Students must check the current textbook and syllabus to be sure that they are up to date.
