Satellite passes#
Note
Updated 2024-06-20T17:42:24.629465.
Here are some details for the satellites we’re likely to work during Field Day. The information is taken primarily from Clint K6LCS’s website, and with help from Mike KB8BMY and Frank KJ7DZ, with thanks. The frequencies in the tables below contain uplinks and downlinks, with Doppler shift taken into account for aquisition of signal (AOS) and loss of signal (LOS) times.
