24/7 Frequency Monitoring and Recording Now Installed at the Field


Thanks to the unstinting efforts of several club members, we now have the capability to continuously monitor the radio spectrum at the field, to determine whether there are environmental or malicious attempts to interfere with our legitimate use of the 2.4 GHz band. The park is still working on making a permanent power connection for this effort, so that's why you will see an extension cord going from the power panel into the large shed vent in the interim.
