Articles and Projects from VHF Communications
The following selection of articles from VHF Communications Magazine has been selected as a cross-section of what appears in the magazine. For earlier articles, due to the nature of the DTP system used to produce the magazine, and partly for obvious commercial reasons, the diagrams and figures from the articles have not been reproduced. For articles since 2000 the full articles can be downloaded as pdf files. If you want a copy of one of the articles, all back issues are available, see the back issue pages. However, we hope that enough information can be ascertained to show the quality of projects featured in the magazine, and whet your appetite enough to subscribe!
