VHF Communications was a quarterly magazine published between 1969 and 2013 especially for radio amateurs and professional RF engineers. It covered the VHF, UHF and Microwave bands. The magazine started as the English version of the German magazine UKW Berichte. Over the 45 years of publication it covered many topics from valve equipment through transistorised equipment to RF Integrated Circuits. The designs were published with full circuit diagrams and printed circuit layouts. Many theoretical topics were covered such as; antenna design, oscillator design, transmission theory and the practical use of modern RF modelling and design software.
Kirk Bailey, N7CCB has enhanced the pdf files for the complete magazine DVD. He has taken the original PDF files and used an advanced OCR process and converted them to PDF/A format. There are two additional folders on the 2014 edition of the complete DVD that contain:
All magazines from 1969 to 2001 in PDF/A format with OCR text overlaid on the PDF image so that text can be extracted. The OCR process had some difficulties with older magazines where the resolution was poor. Magazines from 2002 to 2013 in PDF/A format have been visually enhanced but there is no OCR text overlay - the only text included is whatever was in the original PDF file
