Whatever the satellite, if you're trying to stretch the footprint, your sked is always going to be at the peak of elevation, for that fleeting moment when the satellite is a few degrees above the horizon. That means that you're always going to be at zero doppler shift, and the math will always be the same. Find yourself once at TCA on any pass, and lock them in. The numbers will be the same for your sked.

> This is probably simple, however, I need a quick and simple way of determining my uplink frequency given a specific downlink frequency. Usually I will just send a few dits to find myself. When trying to work a sked footprint edge to edge I need to be at the right frequency at the right time, without hunting around for myself. I am refering to AO-7
