AO-27 is still very much alive but needs to be in sunlight for the repeater to work. I work it almost every day. SO-50 is another FM satellite that is in service. It's available day and night and requires a PL of 74.4 to turn on, and 67.0 to talk. Check out the AMSAT website at http://www.amsat.org/amsat-new/satellites/status.php. Also, Fox 1 will be available in the near future.

AO-27 is still going.  It is only active for 7 minutes during daylight passes over the Northern Hemisphere (generally between the latitudes of Miami FL and the USA/Canada border), as a way to work within the old rechargeable batteries on that satellite.  Even with that limited schedule, it is very popular.  More information about AO-27 is available at http://www.ao27.org/

SO-50 is similar to AO-27, but with half the downlink power (250mW from SO-50, vs. 500mW from AO-27).  It is gaining in popularity since AO-51 went silent in late November.  Both of these FM satellites use the same frequency pair - uplink on 145.850 MHz (no PL required on AO-27, 67.0 or 74.4 Hz PL for SO-50), downlink at 436.795 MHz +/- for Doppler.  An Arrow dual-band Yagi, or Elk log periodic, or any number of homebrew directional antenna designs you can find online, will work with an HT to use these satellites.

No - not gone. But one needs to perform an extra step in working it: In addition to checking its orbits, you need to cross-check with the AO-27 op schedule.

All the links are on the http://www.work-sat.com for you.

SO-50 is still up and running. And we'll be listening to the Russian spacewalk outside the ISS on both NASA channels and also the Russian spacesuit frequency as it passes over us tomorrow!

Currently, FM operational SATs are ISS, AO-27, SO-50, and with some luck - soon SO-67, again.

For current FM Voice SAT info DL file name 'VoiceSatsXX-XXXX.pdf' at:  Wink
http://groups.yahoo.com/group/HAM-SATs/files/SPECIAL_SAT_Info/

To see what SATs are currently operational, at:  Shocked

What sats are easily wordked now? From the SAT SKEDS page at http://www.work-sat.com ...

SO-50
- up and running

AO-27
- up, but you need to check not only its orbit, but its schedule - links provided

SO-67
- being worked on - possibly back in March, 2012!

ISS
- check the links for the ISS Fan Club - provided

For you SSB and/or CW folks, there's AO-7, FO-29, and VO-52 - I do *not* go into
these sats on my site, as the site is devoted to getting folks on to the FM
voice sats with minimal equipment. Other sites cover these birds well for you.

And use the Live OSCAR Status page - http://oscar.dcarr.org - as it lets you know
whether or not others are working the sats sucessfully.

FYI to all, I just updated my Amateur Radio VoiceSATs PDF file - giving all the most current data needed to operate 'active' voice SATs.  Cheesy

NEW >>> added a page to this PDF on how I program my radio memories for SAT OPs.  Grin

You can be DL the PDF at: http://groups.yahoo.com/group/HAM-SATs/files/SPECIAL_SAT_Info/VoiceSATs04-2012.pdf

HAM-SATs Yahoo Group is open to ALL.
Feel free to rummage around the FILES area for lots of antenna/SAT info. Suggestions & contributions welcome.  Wink

>> ... updated my Amateur Radio VoiceSATs PDF file ...

Just to have everyone on the same page ...

-There is no "AO-50" FM sat for us to access. We have "SO-50" and "AO-27" as two workable FM birds. And packet through the ISS.

-Proper citation of amateur radio CTCSS tones should always have them with one decimal place/unit - that is, the citation should always be in xx.x or xxx.x format. A citation of "74" is not one of the common CTCSS tones. SO-50 uses a CTCSS tone of "74.4" to activate its ten-minute timer. May sound trivial, but there are folks who can actually program "74" (or 74.0) in their radios (like Motorola folks).

So when you choose your sources for information, make sure you are receiving complete information.

I'd like to thank you for publicly pointing this minor trivial error here & on HAM-SATs Group. We would not want to confuse anyone between the only two currently operational FM SATs; AO-27 & SO-50.  Huh

Your PL concern is also trivial as I give SAT HAMs far more credit in being smart enough to understanding CTCSS tones.  Grin

But please be more specific next time; the first page "SAT Frequency Summary" is correct with no errors.  Shocked

The egregious error was on the newly added "SAT Radio Memory Programming" page that misstated SO-50 as AO-50, again an error that would NOT have prohibited use of SO-50.  Cool

I've just posted a slightly revised update for all to enjoy and DL:    VoiceSATs05-2012.pdf 
At:  http://groups.yahoo.com/group/HAM-SATs/files/SPECIAL_SAT_Info/

In this same folder there are PDF files for programming IC-91AD, TH-F6A, KG-UV3, more to come for your reference use.
  Cheesy

I'd like to point out a FACT, I as HAM-SATs owner get no monetary compensation from Yahoo, any moneys derived from Group users goes to Yahoo to keep these sites open and FREE to all.  Tongue

Don't forget the third currently operational FM bird: the ISS!

>> ... Your PL concern is also trivial ...

Well, not "trivial" to the gentleman who took the information literally, programmed his rig according to your published chart, and was unable to properly work SO-50.

If one is going to publish information that is used to "teach" others, then is should be free from not only grammar and language usage errors, but also be completely accurate. I mean, if the "educators" cannot get it right, how can we expect our intended audience to trust us?  (grin)

>> ... I as HAM-SATs owner get no monetary compensation from Yahoo ...

Didn't realize that was an issue ... If you DO find a way to receive money from Yahoo from our efforts as list owners, please pass it on!
