Here is a picture from the front cover of the December 1973 edition of RADCOM, showing Alex G8FCQ operating the talk-in station (GB3ARE) at the second Midland Amateur Radio and Electronics Exhibition. This was the first year that the "show" was to be housed at Granby Halls which would become it's home for many years (later to be taken over by LARS - Leicester Amateur Radio Show).
