Which EEVBlog HOME MADE SPECTRUM ANALYZER

[lordvader88]

Hi, in some EEVBlog Dave went to a gathering of people, and some cool old dude had his HOME MADE SPECTRUM ANALYZER, and it looked so cool, about the size of a VCR (wow we're old). What EEV show was that and where's a schematic for a home made SA on that level ?
