Thank you everyone for your help. I had my first successful contact on SO-50. 

AO-27 appears to be on hiatus, since the website is also down. 

My next endeavor is learning the linear transponder birds. I have been trying to receive AO-7. I never heard a beacon on either mode A or B. (Daytime pass) I tuned around the downlink and I might have heard some very faint stations. I guess I need bigger antennas? Perhaps some phasing cables will help. (it's in the mail)

Thank you KB5WIA for the contact this evening.
