Happy New Year all

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
