Eric,
Thanks for you input. I do have an additional question?... about the need of
CT-17 level converter as noted in
the owners manual, but I think Mike will answer it when he replies. This,
to me, is the last piece of the puzzle
(and my confusion). Is the ?Y' adaptor cable to be used ?in conjunction?
with the CI-V level converter or?..?in place
of ' the CI-V level converter?
Again, I?m really impressed with the helpful responses I?ve received from
this group, thank you.
I feel like I?m almost there ;0)
73
Tom
ps; from the looks of the archives, you have been involved in helping others
for a long time !!

Hi,
We had a problem with decoding data for FC2 in the data warehouse this
morning (31st Nov).
This has been fixed and if you have any bin files which you recorded
between 0:00 and 14:00 utc, please replay

All AMSAT-NA Members,
The annual election packet was mailed prior to 15 July, and should have been
received by now. Many
members have already returned their ballots. If you have not, please take a
few minutes to review the
position statements of the various candidates, make your selections, and
then mail them. This is
especially important if you are in a non-North American QTH. In that case,
it is strongly recommended
that you use air mail or other expedited means. This is your opportunity to
select the AMSAT-NA
leadership and help chose the future direction of our organization. Due to
unusual circumstances, we
are electing 4 full Board members, in addition to the usual 2 Alternates, so
you may vote for up to 4
candidates.
73s,
Alan Biddle

Subject: [amsat-bb] AO-7 CW Telemetry
Message-ID: <593712.68900.bm@xxxxxxx.xxx.xxxx.xxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
It is very rare to hear clear CW from the AO-7B
telemetry beacon around 145.972. Most of the time
there is no beacon at all. Sometimes there is
jibberish. Usually the signal is very weak.
With AO-7 going through eclipse on every orbit, the
satellite can come out of eclipse in different modes/
options. Recently there have been times where the
beacon has transmitted clear CW over North America,
something I have not heard over the years.
According to the DK3WN website, there was some cw
telemetry back in 2002 when the satellite was discovered
to be working again. And there was some discussion about
what is valid data based on the last 3 digits sent in the
24 group block of data. If the value is 649, 650, or 651,
the data is likely valid.
I first heard the image of the cw signal around 958. It was
so loud I thought it was a valid user at first. But since
the cw was all numbers I tuned up to the beacon frequency and
there the signal was louder than anything I have ever heard
on AO-7. It took a while for me to get the recorder running
but I managed to capture some data. After playing it back I
found that there was only one block of data where the last
group was valid, a 649. Other later transmissions were loud
but the data was much different and the last group was not
correct.
I couldn't locate a telemetry calculator at first so I decided to
build one on Excel using the formulae provided by DK3WN. The
data follows:
AO-7B Telemetry 24July2014 2318UTC

There are some values which are obviously not correct.
Some sensors might not be working properly since some
values are out of range. However, the solar panel numbers
might be somewhat correct. I wouldn't doubt it if the
transmitter was putting out 7 watts at the time.
Perhaps there are those who are familiar with the AO-7
telemetry that can make some sense out of the data.
Unfortunately we don't have multiple blocks of good data
to compare readings. Maybe some have recorded recent CW
data and can find some good blocks that can be shared here.
The data was copied on my Arizona remote and Skype was being
used to listen. But I am fairly confident that the cw copied
is correct.

That is why I want so much to continue the 145.825 digipeater on as many
satellites as we can*.
But we can?t seem to inspire any of the other HUNDREDS of satellite
building groups to consider it.
I think there were over 100 cubesats launched last year. None with 145.825
APRS?

First circumnavigation of the globe by an amateur radio carrying
balloon, and as it passes the milestone...
"So, can you get another lap out of it?"
What about poor old M0XER-3? It's still out there! Sure it got waylaid
in Nunavut for a while, and let M0XER-4 slip on by... It needs some
encouragement too!

Trevor,
The M0XER-4 (I thought) did frequency shifting (APRS 144 MHz national
channels over Europe and the US), and so I thought it had more complexity.
The image shown on the link below only has 434 MHz antennas, no obvious
GPS and no VHF antennas. Can you clarify and help us get an idea of what
this M0XER4 payload actually looked like? Thanks, Bob, WB4aPR

Has anyone tried one of these for portable use ? It has cross band repeater
and also functions in Full Duplex.
I just ordered one but need to get another hand held antenna, when I do I'll

Craig,
Patrick, WD9EWK, has tested one of these on SO-50. Unfortunately
desense makes it unsuitable for use on Mode J FM satellites. It may be
usable for the upcoming fleet of Mode B FM satellites, including EO-80
and the Fox-1 series.

Hi Bob,
Yes, that's a library image of one of Leo's solar powered payloads, I don't
have a pic of B-64.
If you send Leo an email I'm sure he'd fill you in on the details - I'm just
amazed he's managed to get everything into such a small and light package,
as you might expect the rechargeable cell is the heaviest part.

John,
The December 1974 issue of the AMSAT Newsletter covered AO-7 telemetry
fairly in depth. Included was a description on reading the telemetry
followed by a telemetry conversion table.
You can find the issue in Phil Karn's archive
http://www.ka9q.net/AMSAT-Newsletter-1974.pdf
The article begins at about page 100 of the PDF

Hi Craig!
As N8HM mentioned, I have tried the KG-UV8D on SO-50. It will not work
for cross-band, full-duplex operation on this satellite. Using a group
of memory channels, its receiver is OK for hearing the downlink when
working SO-50 half-duplex, or as a receiver when transmitting with a
second HT (even one of the cheaper Baofeng HTs!). There has been a long
discussion thread about this radio on QRZ.com's satellite forum at:

not-full-duplex-by-itself
Like with many Kenwood and Yaesu HTs, you can program a group of memory
channels to work SO-50 half-duplex. Make sure to set up the memories
where the receive/output frequency steps down in 2.5 kHz steps. Otherwise,
there are times, around the point you would change receive frequencies,
where you won't be able to hear the satellite on either frequency when
tuning in 5 kHz steps (i.e., from 436.800 to 436.795 MHz). All versions
of this radio with firmware at V1.02 or greater tune in 2.5 kHz steps,
so this means you'll end up with twice as many memories for working
SO-50 than with other radios incapable of tuning in steps smaller than
5 kHz. (To view the firmware version in a KG-UV8D, press and hold the
3 key while turning on the radio)
Beyond SO-50, the KG-UV8D will work OK for V/U cross-band full-duplex
operation, if the 70cm signal you're trying to hear is a lot stronger
than the SO-50 downlink. The receiver is certainly better than the
Alinco DJ-G7T 2m/70cm/23cm HT - another one that was promoted for
cross-band, full-duplex operation a few years ago. I find myself
grabbing the KG-UV8D more often when I want to have an HT with me,
unless I'm looking to do APRS using a TH-D72A instead.
While at the ARRL Centennial Convention in Hartford a couple of weeks
ago, I did a test with my KG-UV8D and the Fox-1 prototype on display
at the AMSAT booth. The Fox-1 series of satellites (remember 3 have
launches - go AMSAT!) are U/V satellites, the reverse of SO-50. You
will transmit on 70cm, and receive on 2m. In this configuration,
and making allowances in an attempt to better simulate working a
Fox-1 satellite in orbit, I was able to work the Fox-1 protoype
full-duplex walking around the main hall and just outside the hall.
I varied my transmit power between high and low, and moved my antenna
around, trying to change how the received signals sounded as I
transmitted. The Fox-1 prototype used a dummy load as an antenna.
I was able to hear myself without any noticeable desense at either
transmit power level, even when the Fox-1 prototype's downlink
started to sound as weak as SO-50 typically does. I received good
signal reports from Burns W2BFJ, a member of the Fox software team
at the AMSAT booth who listened to some of my tests. This gives me
hope that the KG-UV8D - and other radios like the newer versions of
the IC-W32A - might work for cross-band, full-duplex operation with
U/V satellites like the upcoming Fox-1 series, when they don't do
the same for V/U satellites like SO-50.
If you want to discuss this further, and the posts on that QRZ
forum thread didn't answer any other questions you might have about
the radio, please feel free to contact me directly.
Good luck, and 73!

Has anyone tried one of these for portable use ? It has cross band repeater

Tom,
You need one CT-17 or equivalent level converter. I use the West Mountain
Radio RIGtalk which is a USB serial port to CI-V interface. Many people
build their own (easy for an RS-232 serial port) or buy inexpensive
converters from ebay.
The CI-V interface is an "open-collector" party-line. You can parallel 2-4
Icom radios using Y-adapters, then connect it to the CI-V output of the
CT-17, RIGtalk, or other similar interface.
Does that answer your question?
73, Steve N9IP
