AO-7 frequencies
by William Herbert Sims 01 Jan '22

So, I have been trying to work stations on AO-7 lately. Something got buggered up in my database – I am not hearing any uplink/downlink nor the beacons. What are the frequencies for the beacons (U/V) as well as uplink and downlink (again U/V)? I have visited several website and I get different answers. Thanks Herb N4RG

XW-3 issues and tips for success?
by John Brier 31 Dec '21

31 Dec '21

So, I tried XW-3/CAS-9 on the first orbit and once later but didn't have any luck finding myself on the downlink. I want to try again but it seems the bird has issues and I'd like to understand more about those issues so I can have better luck next time I try. On Twitter I've heard others say the sat is weak, has high SWR, not a sensitive receiver, noisy at TCA, fluctuating AGC, etc. It's also possible that the RX sensitivity issue is only bad at the edges of the passband, forcing people to work in the center. Has anyone confirmed that? What's up with the AGC? What kind of uplink power/ERP is required/recommended? Maybe we can come up with some general tips to make successful contacts on this bird more likely. 73, John Brier KG4AKV https://twitter.com/k8yse/status/1476022600593809411 https://twitter.com/k8yse/status/1476047464796987400 https://twitter.com/dk3wn/status/1476276565285687312
