CQ-VHF Magazine Index


CQ VHF is a ham radio magazine for ham radio operators whose operational and technical interests lie above 50 MHz.

The magazine focuses on radio technology, products, and activities that exist on 6 meters, 2 meters, 440 MHz and above. CQ VHF covers a broad range of skill levels, from the new Technician to the Extra Class microwave experimenter, and includes operating, technical and construction articles.

CQ VHF is published by CQ Communications, publishers of CQ Amateur Radio magazine, WorldRadio magazine, and Popular Communications magazine

CQ VHF Magazine was first published in 1996. The magazine had been published monthly from 1996 to 1999. The weak advertising and newsstand sales market made it economically unviable by the end of 1999.

It was announced in January 2001 that CQ VHF would come back Spring 2002, redesigned as a quarterly publication with these marketplace realities in mind and will rely primarily on subscription revenues to meet expenses.

Index Information

After completing an indexing project for 73 magazine, I noticed there wasn't a master index available for CQ VHF.  

As most of my interests lie on VHF above, and having acquired most of the issues since the publication went quarterly, the CQ VHF indexing became a new project.

Below is what I believe to be a complete article listing since the magazine went quarterly.  

Periodic updates will be made to this index as time allows.

This index is freely sharable, but please contact me if you plan to redistribute it commercially.  

Enjoy - Steve, KB9MWR
