[amsat-bb] Unsuccessful Uplinks - AO-92

I’ve just started playing with talking on satellites. I’m able to hear all the satellites (AO-85, AO-91, AO-92 and SO-50) that I have programmed on my Kenwood TH-D74, which I use with my Elk dual band periodic log antenna. However no one can hear me or responds to me. I’ve only been successful with my uplink (being heard) on AO-91 on several passes. I triple checked my frequencies on my radio and the 67 Hz tone and they are set as follows:
Sat.        Xmit       Tone
SO-50   145.850  67.0 Hz
AO-85   435.170  67.0 Hz
AO-91   435.250  67.0 HZ
AO-92   435.350  67.0 Hz
These are the frequencies used when the bird is at its peak. I adjust for doppler on 440 by starting out 10 khz less, e.g AO-85 435.160, 435.165, 435.170, 435.175, 435.180. 

Any ideas if something has changed from what is published or am I missing something? Like I said, i’ve been able to communicate on AO-91.
