The Central States VHF Society, Inc. (CSVHFS) is a not-for-profit organization chartered in the state of Missouri. It was begun in the mid-1960s to foster amateur radio operation on the bands above 50 MHz. Membership currently numbers about 300, principally in the Midwest states. However, it has members in states from the Atlantic Coast to the West Coast as well as Canada and several foreign countries.
The CSVHFS holds a Technical Conference once a year. The goal of the conference is to raise the technical level of amateurs by providing a forum for presenting technical papers relating to VHF, UHF, and Microwave, to provide a focal point for the discussion on operating practices and procedures, on exploration of modes such as EME, MS, FAI, E-skip, etc. and other topics that promote operation on Amateur bands above 50MHz.
Proceedings from these conferences are published by the ARRL and can be purchased from the League.
