AO-27 failed in October, 2012, and attempts to restore it have failed. PO-101 is usually on Fridays and Sundays over North America. AO-92 is in the L/V mode on Wednesdays for 24 hours and U/V the rest of the time. There are severak FM bird operational at this time: SO-50, AO-91, AO-92, PO-101. If you can't hear any satellites, ask for help. Just because you can't hear a satellite doesn't mean that you are not getting in and possibly interfereing with those running less power. It is easy to transmit into a bird but much more difficult to hear it. Don't announce your call and grid if you are not hearing others well enough to copy their callsigns. If you are not hearing anyone, you are likely not hearing the satellite. SO-50 is difficult to hear due to its 1/4 watt output and its propensity to polarity shifts. Most SO-50 daylight passes over the United States are very active. Once you are hearing, call someone you can copy and make your contact. Most importantly, please do not transmit unless you are hearing stations well enough to copy their callsigns. Before you know it you'll be at ease with operating on the birds. If it doesn't go very well for you the first time, regroup, determine how you could do better and then try again. Don't get excited listen to the call and then respond accordingly. A new callsign on the birds creates interest, especially when the new station is hearing well and responding to calls. Or have someone log for you so you can work those who call you. Use a digital voice recorder if you have one so you don't have to write anything down. Someone else will likely call you immediately if your callsign is unfamiliar. Listen to the protocol, know your grid and the exchange and by all means, keep listening after you make your first contact. AO-51, which was the easiest bird to work, became a silent key at the end of 2011. Likely that will be SO-50/AO-91/AO-92 (since AO-27 and AO-51 are no longer operational).
If you are new to satellites and want to make your first contact, the best thing to do is to listen to some of these recordings, especially the ones from the satellite you are going to use. The website is sponsered by WA4HFN and WA4NVM, both

It will contain information about the Gridmaster Award, the 5 in 55 Award (for working 5 stations in EM55) and how to apply for these awards. Enjoy this very unique facet of ham radio!Īlso of interest is the website.
Or go directly to the page at: Doing these things will make it easier for you to operate satellites. Then select "Mailing Lists & Services" on the drop down menu. It can be accessed from the website by clicking on "Services" near the top of the main page. Lastly, make sure you check the AMSAT Website for the current operating schedule of the birds. It's better that you can be contacted easily if there is a problem. Make sure your email address is correct on QRZ.com so others can contact you. Tjeu are usually happy to help out with any questions you might have. If you need assistance, get in touch with others you hear on the birds that are successful in making contacts. These are just some of the benefits of having access to the recordings. Is your audio level high enough compared to others on the bird? Look for settings in the menu to adjust mic audio gain. Did you interrupt a qso in progress? Try to determine why that happened so you can avoid doing it again. Are you calling but can't hear yourself on the recording? Check your transmit antenna, frequency etc. Are you being called but not hearing? You may want to work on your receive antenna. You can hear what you did right and what you did wrong so that you can make changes in the way you operate.
However, the major reason for doing it is to allow everyone to hear what they sound like on the birds.
Perhaps the most common use is for deciphering callsigns that may have been copied incorrectly. (REVISED 11 February 2020) Some have asked about the purpose of having these recordings on the web.
