Am I correct in understanding the Uplink frequency shifted to 435.170? I just followed a low angle pass on Orbitron and used 435.170 as the Uplink frequency. With that data entered, the transmit doppler started around 435.162 and ended at 435.175782. So, basically the following three frequencies should do it for getting in; 435.165, 435.170, and 435.175.

That has been the observation I have heard from many users.
We (AMSAT) plan to test the frequency of the Fox-1Cliff and D receivers at temperatures of 15C and 25C, perhaps higher. Fox-1A thermal design indicated that it would operate around 0C average so the transmitter and receiver were calibrated for that temperature. Once we know what the frequency is at these higher temperatures, we will share that in order to help you all find the best uplink frequency for AO-85.
