Hi!
I had asked this question on Twitter when the tweet announcing that
AO-92 would remain in U/V mode appeared, just over a week ago. Not
seeing an answer from the AMSAT Twitter account, I'll post the
question here, expanding on what I wrote in my tweet.
When AO-92 was switched into L/V mode on the evening of 8 December, the
@????? Twitter account posted the announcement of the mode change, along
with a mention that L/V mode will not be available the following weekend
(14-15 December) due to the N4T expedition to EL84:
https://twitter.com/AMSAT/status/1071609972902060032
"AO-92 placed in L/v mode at 0330UTC and will revert to U/v in 24 hours.
No L/v next weekend by request of EL84 N4T expedition."
I asked a question, and saw no response on Twitter from the @????? account.
Back in October, a request was made of AMSAT by Tom N5HYP not to activate
AO-92's L/V mode during the Jamboree on the Air weekend, so the satellite
could remain in the normal U/V mode. Drew KO4MA posted a reply that
explained his answer, here on the AMSAT-BB list:
http://amsat.org/pipermail/amsat-bb/2018-October/069962.html
"Tom,
In a private email response sent to you just prior to your email to the
-bb, I inquired whether you had SSB capabilities. I know many other JOTA
stations do get on the transponder satellites as well, and I think we can
agree this would be a better presentation of our part of the hobby. I'm
not inclined to alter the schedule when there are so many other satellites
available, both FM and SSB/CW, but only one L-band uplink available one
day a week. Of course AO-92 will still be available in U/v for the first
half of JOTA.
73, Drew KO4MA
AMSAT VP Operations"
I was surprised to see this response, but it seemed reasonable given the
fact we currently have a lot of satellites that support voice QSOs in FM
and SSB. I heard JOTA stations working FM satellites that weekend, and I
worked one of them on AO-91 during a Saturday afternoon pass. It is always
fun to work the Scouts during JOTA.
Fast forward to the AMSAT tweet on the 8th... Given this response from
October, and seeing that something different was going to be done with
AO-92 for what could be characterized as a family camping trip to the
Florida Keys, I asked:
What changed?
The situation now mirrors how things were during JOTA in October. We still
have a lot of satellites supporting FM and SSB/CW. AO-92 remains the only
satellite currently capable of working with an L-band uplink (until the
L/V repeater on the ESEO satellite is made available to us). And AO-92
would be available in U/V mode for 3 of the 4 days of this family camping
trip, had the normal Saturday evening switch to L/V mode happened.
JOTA is a worldwide event involving radio and Scouts. N4T is (was) not a
worldwide event, at least on satellites. The grid EL84 has been active on
satellites at least twice in the last six months. Yet AMSAT accomodated
a request to not activate AO-92's L/V mode for an event that won't have
worldwide participation via satellite, after not making the same
accomodation for a worldwide event. This is the reason for my question.
73.

I'm sure that this is being considered, but I'll extend the thought anyway:
If there has been a collision that may have damaged or sheared off the
RX antenna, could other damage have occurred that might be identifiable
via telemetry?? What I'm thinking of is possible damage to one or more
solar cells.? Would damage, perhaps resulting is reduced current flow
or voltage levels, be discernible through the telemetry?? Are there other
items of the surface of AO-95 that, if damaged, might reveal that damage
through telemetry.
Thanks to all the volunteers that have worked so hard to make the FOX
series an outstanding success!

Dear All,
Also noticed quite a difference on AO-73 reception this side, it used to be
100% reliable but less decodes theses day, I have not investigate same but
for sure there is a degradation somehow.
Just FYI

I have been using two TS2Ks for a number of years on the sats. The only
issue ever was when the prolific chipset usb/serial adaptor started acting
up. Per recommendations on the TS2K yahoo group, went to FTDI chipset
adapters (UGreen- Amazon) and have had no further issues. The other
variable is to make certain you are using the TS2K's max data transfer rate
(57600)- menu no. 56 and that SATPC is also set for that speed.

I am talking about the doppler. I am also using a older USB converter that
I have used for several years. Never had issues with this converter. 19hs

to ser which one it is. Tripplite purchase the company several years ago

I hope to get some more things figured out as time goes by. Just seems odd

Interesting!? Didn't know that data was available on line.
Is there a more detailed presentation of the data in, say,
a spreadsheet for a greater period of time than what
is presented?? This would be very helpful in performing
any detailed analysis.? Is all of the telemetry presented
on the web page?? All data would be valuable in trying
to make any correlations.
Where in the receive chain is the RSSI measured?? Has
an attempt been made yet to transmit a strong signal
(modulated or unmodulated) during an overhead pass
to try to 'nudge the needle' on the RSSI meter?? Perhaps
successively stronger transmissions could be made to
see at what power level any change occurs in the RSSI
without applying too much power.? I recall someone
mentioning approaching an EME operator to attempt
transmitting at AO-95 with significantly more power than
normal.
Why does the 'Battery I32C' indicate 'FAIL' (although I see

All of the telemetry can be downloaded and analyzed thoroughly through

all values can be exported to .csv files for analysis in other software.
