    Seems I have to slog through list of linear satellites, defunct satellites to find few FM that may or may not be active?

    Can active FM sat users post a list of FM satellites useable in North America (I am in So Cal)
    EDIT: Also any Digipeater sats as well

    Thanks

    Just the easy sats cited at work-sat.com for you ...

    But that AMSAT link has ...

    FM Repeater Satellites
    (Click here for frequency chart, follow links below for satellite details)

    Transponder Satellites
    (Click here for frequency chart, follow links for satellite details)

    Digital Satellites

    ... and even more information!

    Thank you for that PDF on work-sat. That is what I was looking for. So it seems there are only 2 active FM sats (not counting ISS)....?

    What about digipeaters? I recall trying Falconsat3 but never got through.

    Now for the real life info on FM birds

    Not Many

    We had more FM satellites that were usable years ago.
    You would think in the 21st century There would be more FM satellites but everybody goes digital it seems.

    SO-50, AO-27, PO-101, AO-91, ISS ... more than 2...

    Ok so AO-27 added to list, note that one isn't on your PDF @K6LCS. Is there reason for this? I read it's only "Currently on for four minutes on ascending and descending passes over mid-latitudes of the Northern Hemisphere" is that the reason?

    So far the FM easy to work list is:

    SO-50
    AO-91
    AO-27
    P-101
    ISS (sometimes when active)

    I reckon this question might be annoying to the regular sat ops guys, but seriously, even with google and some quick searches it's not so plainly easy to reach this list (seems there are many defunct or sporadic satellites)

    The number has fluctuated for all satellites over the years. Just a few short years ago, there were only 3 active amateur radio satellites with voice transponders available (SSB+FM.)

    There are advantages to having a diverse fleet. I like them all - FM, SSB, digital. Different groups have different priorities. It is unrealistic for anyone to demand/expect a particular type of satellite be developed to their liking without making some significant technical or financial contribution.

    AMSAT's site is typically very current, such as the link @KB1PVH shared. There is no single Internet authority or ruler over what sites consider a satellite operational. Sometimes the satellites' status change in an instant. Some satellite owners/operators are silent - others provide information via a news service or web updates.

    SO-50 and AO-27 are usually the easiest to work. AO-91 would be next, but only during daylight hours. I've never had much success with PO-101, but YMMV.

    Anyone who gets annoyed at new people asking relevant questions is nobody worth paying attention to. CSB, you are totally fine. I would honestly say that satellite folks are generally the most helpful and agreeable hams I've come across in the hobby. I agree with you that information regarding satellite use is not as cut and dry as in some other aspects of amateur radio and it can sometimes seem to fly in the face of what some folks get used to. Using tiny objects flying through space at many thousands of miles per hour, hundreds of miles away to try and talk to other earthlings within a very specific 10 to 15 minute window is an animal unto itself!

    Keep asking questions and you will get good answers here.
