Making contact with AO27

[GPersons <railfan@xxxxxxxxx>]

Hi group,
I have been trying in vain to talk to AO27. I can here the satellite just fine but I have not been able to make a voice contact.
I am using an Icom W32 HT at about 5 watts with a Diamond RH77CA antenna. I uplink on 145.85.
Can anybody tell me what, if anything, I am doing wrong? Is it that fact that I don't have enough antenna, not enough power, wrong uplink frequency or what?
Sure will be glad when my ARROW antenna arrives!
Helppppppppp!

73 & Thanks
