Hi Mike!
The downlink is 435.800.
The photo at the following URL shows late in a pass when the doppler-corrected downlink freq at my location had traveled to around 435.790.

But with USB, it gets tricky... using an SDR, you visually adjust the signal's position to keep the audio output centered on 1500 Hz (the middle of the 3KHz audio bandwidth).
Accomplishing the same thing with a regular radio seems like it would be very difficult without any visual feedback to make fine adjustments.

Would someone please repost the corrected downlink Telem frequency to use for Doppler control.
Thanks!
