Hola Felix,
I just wanted to say something about your thought that the issue with AO-85 is U/V vs V/U. We realize there are issues with AO-85, but this is not necessarily related to the uplink vs downlink band. We plan to address the issues that have been found on future members of the Fox-1 series.
If you are on Facebook, you might want to check out the AMSAT North America group. There is also an AMSAT-UK Facebook group and probably others.
Good luck and have fun with SO-50 as well as this great new crop of satellites being launched all around the world!

Hi everybody from Spain,
first of all, thanks for your patience. I am a new HAM since October 2014 and I have just begun with satellites some months ago...
I want to add the point of view of a newbie to sat operation like me to the list, specially for people that could be beginning like me.
First of all, as a newbie, I only have a Baofeng UV-5R (half duplex) and an Elk Antenna. I think this could be the very first beginning equipment for everybody (this is only 30 eur + 200 eur = 230 eur). I use ISS detector for tracking (it is better for me than Amsat Droid Free because it has a compass, so the track is really easy).
When a SAT is going to pass near my QTH I go down to a park after walking 15 mins and there I connect the Elk to the Baofeng.
With this, it has been very easy for me making contacts in SO-50 including not very high passes. Why? Because when I hear people I know I can work them. When I hear somebody calling, I am sure that when I press the PTT i will be in the SAT. Hearing people gives you a lot of information in SO-50.
This is not the same when I try AO-85. I hear people all the time, but that does not guarantee me they will hear me. Maybe I am 5 Khz down or maybe I am 5 Khz up and because I am working half duplex, I can't check it. I have to wait for silences and try other freq. I haven't been able yet to make a contact in AO-85.
The conclusion for me is that it is easy to work V/U FM satellites in half duplex and it is complicated in U/V at least for people beginning like me.
I tell this because I have read in the AO-85 document all the advantages that U/V mode has but I don't know if that compensates the added difficult it has for people working with modest half duplex equipment. So this does not seem an entry satellite to begin with...
This is a just beginner comment on the SAT. I am sure in next passes I will be able to make some contacts with some luck (I am going to buy a Midland CT-890 full duplex HT too).
I want to congrat the AO-85 team for their work. It is indeed a great sat! :) but I wanted to share my thought about if it is not better to have and V/U repeater than an U/V one.
Thanks everybody. I am learning a lot with this list.
