At AOS, you should be around 160 and then tune up in 5 kHz increments as needed to 180 at LOS. That has worked the best for me. If you are computer controlled, then set your center frequency to 435.172 MHz.
Uplink polarity makes a massive difference as well. If you're fixed vertical or horizonal polarity, you'll find times when you cannot access the satellite.
200W EIRP is the recommendation for full quieting horizon to horizon, but remember that trees cause losses on 70cm, so you may have to increase your uplink power to get through trees or compensate for polarity.

Having a little trouble getting into the bird. I noted that the uplink is 435.180 with a 67.0 tone. However, I read that due to temperature variations the uplink is closer to 435.172. Tried the 180 w/out luck. Any suggestions on the successful uplink frequency? Tested the 435 antenna on receive and having no problem hearing in that band, so I am assuming I am missing the bird frequency on my uplink.
