AO-16 has been in its "voice mode" continuously for nearly a month now. Many thanks to all the users of this "new" bird!
It is time to pause voice operations long to receive some MBL telemetry (limited as it is, it's all we have). Around 0920 UTC on 17FEB08 I plan to return AO-16 to digital mode in order to receive some telemetry. If all goes as planned, it should be back to "voice mode" during the same pass. If not, I'll try to catch it on the 1056 UTC pass. Most of you will be asleep, so I don't think it will interfere with too many contacts.
Looking to the future, we can see that after several months of continuous illumination, AO-16 will begin to experience eclipse periods at the end of March. The eclipse periods will increase and extend through the summer. This may impact AO-16's power budget such that the transmitter output will have to be reduced in order to protect its 18 year old batteries. We'll know more after the eclipse periods begin in late March and early April.
In the meanwhile, enjoy AO-16 and her strong signals!

I have an ICOM w32A in very good condition for sale. I bought it new and it
has been well cared for. Includes radio, antenna ,wall charger and manual. I
do not have the original box.
This model is the last handheld that was produced with full duplex. Great
for the sats with an Arrow.
Price is $200 (includes shipping in CONUS). Inquiries off line at [email protected]amsat.org.

Congratulations on surviving the first calendar month since June 1913 which
had no reportable sunspots. And counting. Of course, we satellite
operators don't need no stinking sunspots, but have a word of sympathy for
your friends who work only HF.
Congrat's to Joe, K3SZH & Fabio PY4AJ on reaching of TOP in "AO-7 DX List"
with a NEW record for Longest Distance *confirmed* QSO ! 7438 Km !
Stay tuned till the next month-updating.
I have already received New QSL cards !

It looks like the temperature has come up enough on AO-16 that the watchdog
problem has gone away. I turned the satellite on this afternoon on the
~1920Z pass, collected some telemetry, and then commanded it into bent pipe
mode. On the next orbit, it was still on, and in bent pipe mode. It may or
may not stay on. The command team will monitor http://oscar.dcarr.org/ and
amsat-bb, and if the satellite goes quiet we will endeavor to restart it as
soon as possible. Occasional interruptions to gather telemetry are likely.
Just as a reminder, AO-16 now operates as a cross mode, cross band voice
repeater, with an uplink on 145.920 FM. The downlink is reduced carrier AM,
similar to double sideband, on 437.026. Most stations find receiving the
downlink on USB works best.
Work is continuing to predict how long this latest period of operation may
last, but initial estimates are around 2-3 months total, symmetric around a
period of continuous illumination in October. There may not be another
opportunity after this one, as the satellite will generally head towards
longer eclipses (and lower temperatures) for several years.

I have both the M2 EB144 and EB432 for sale. They are less than a year
old and come with the radial kits. Asking $400 includes UPS shipping to
Lower 48 ONLY. Reason for sale, I am upgrading to the M2 beams for SSB
operation. US Postal Money Order or Pay Pal (you pay fees)

I wouldn't consider it for satellite work. It is a gain-less design,
even though AOR claims 2.15 dBi (at 144 MHz), 3.0 dBi (at 430, 904,
Difficult to get it "perpendicular" to the birds, too...
Interesting antenna for events - it draws attention. But if you have
to spend some money on weird antennas, grab a M2 Eggbeater for RX.
At shows, I mount my Eggbeater on a rotator...I call it my "Souffle'

I'm trying to collect some data on the typical successful AO-40
portable-type station. What worked and what didn't work for a portable,
throw it in a suitcase type setup, or CC&R evading driveway or backyard
setups, either U/S or L/S. If you have any photos and/or descriptions of
your setup, please forward them direct to me at ko4ma(a)amsat.org , or point
me to a link if you have them on the web. Thanks in advance!
