Reader feedback, comments, requests for clarification or amplification, "grist for the mill" in the form of unclassified data contributions, and all related questions of an unclassified nature are invaluable in shaping the usefulness of this Handbook to you, the reader. Please feel free to contact us - the only foolish question is the question unasked, and all communications with the team will be treated as privileged. The Principal Editor has several decades of experience in this particular aspect of maritime domain awareness, other editors in our team bring just as much experience plus a wealth of experience in RF systems design and relevant software-engineering development, and we can track down unclassified information from some of the most obscure corners of the worldwide web. If you want to know about polyrod antennas and their usage in marine radars, or where to find information on new Russian MNRs, or if you simply want to know how we use Excel to 'crack the code' of diabolical stagger patterns used by some marine radars, such as Raymarine's Pathfinder series, please don't hesitate to ask! The full Handbook, with all supporting illustrations, tables and supporting materials, is just too large to be squeezed onto a CD, far too large for a website, and probably too densely-packed with very dry information for most readers. Queries regarding this should be addressed to the Principal Editor.
