Description

WWV Amateur Radio Club
The WWV Amateur Radio Club originated from the 100th Anniversary of WWV in 2019. After a very successful celebration event in 2019, including a 5-day Special Event Station as well as an official ceremony hosted by NIST, a small group kept the enthusiasm going with other milestone recognitions. In early 2021 the club officially reorganized and has been active since. In addition to hosting an annual anniversary operating event in late September/early October, the club has supported the effort of the HamSCI Grape Personal Space Weather Station project and its most recent efforts during the 2023 and 2024 eclipses. WWV ARC has hosted an FTP repository for HamSCI the past three years, with this service now migrating to the University of Alabama. Most recently the club has helped facilitate a WSPRsonde transmitter, an 8-channel transmitter from 160m-6m, installed at WWV (WW0WWV), that is one of the most reported WSPR broadcasts. Observations of the 1-watt signal have been closely compared with the NIST high-power broadcasts, showing similar diurnal Doppler shifts as well as possible travelling ionic disturbances. The WWV ARC continues its advocacy of the NIST Time and Frequency division and the services provided to the amateur and scientific communities.
