[Marco]

Hi all, I'm Marco and writing from Rome and loves premium communications systems including old data link, better is using motors inside and some special vacuum tubes.Now I'm looking for technical information (i.e. some schematics) about a non common series of panoramic rf fast signal interceptor and indicator built in the end of 70's for ESM / COMINT applications. Thanks and 73
