I think that there are three main components to the Doppler shift for a
satellite orbiting the moon.
1. Earth rotation moving the observer toward the moon at moonrise (+ve
Doppler) and moonset (-ve).
2. Earth-moon distance variation (smaller than 1, and very slowly
changing in comparison).
3. Orbital velocity of the satellite itself.
1 and 2 are easy to work out using EME software, eg WSJT-X or Moonsked. I
can't help with 3.
Taking today as an example, total of 1 and 2 for the moon vary from ~ +3
to -4.5kHz at S-Band.
With DSN satellites many of us use(d) JPL Horizons to calculate Doppler
shift for Deep Space missions. Observing the Doppler shift change when
probes were captured by the target planet was quite interesting (a slowly
changing shift to a cyclic one).

In the coming days the doppler shift on the 70 cm downlink of
LongJiang 2 will vary between +2000 and -2200 Hz (for my QTH).
This can easily be calculated with GMAT using the script I published
a couple of hours ago (see my earlier post).

Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio
satellites.

Help Requested to Monitor for Signals From Chinese Lunar Sats
After their launch on 2018-05-20 at 21:28 UTC, LJ 1 and LJ 2 were
maneuvered onto a track to the Moon. Several amateurs received
telemetry from the satellites. But now LJ 1 appears to encounter
problems.
Quoting Wei BG2BHC:
"Can you help to find amateurs in the US to help to monitor DSLWP-A on
435.425
and 436.425 now?? We lost the contact of satellite A on S band after an
orbit
adjustment.? We just tried to switch on UHF, but we don't know if it
works or
not.
If operating, 435.425 MHz should be 500bps GMSK and JT4 alternately.
436.425 MHz should be 250 bps GMSK.? Both transmit once in 5 minutes.

Updates to AMSAT-NA TLE Distribution
The Japan Aerospace Exploration Agency (JAXA) has announced that three
cubesat carrying Amateur Radio payloads were deployed from the ISS on May 11
at around 1030 UTC. See AMSAT News Service bulletin ANS-133 for details.
The following cubesats have been added to this week's AMSAT-NA TLE
distribution and are designated by Space-Track as follows:
1KUNS-PF (Kenya)- NORAD CAT ID 43466 (a 3U cubesat with a 1200 bps or 9600
bps telemetry beacon at 437.300 MHz)
UBAKUSAT (Turkey)- NORAD CAT ID 43467 (a 3U cubesat with a CW beacon at
437.225 MHz, a telemetry beacon at 435.325 MHZ, and a linear transponder
with a 435.200 - 435.250 MHz downlink / 145.940 - 145.990 MHz uplink)
Irazu (Costa Rica) - NORAD CAT ID 43468 (a 1U cubesat with a 9600 bps
telemetry beacon at 436.500 MHz)
Nico Janssen (PA0DLO) reminds us that it is still too early to tell if the
above CAT ID's are correct for each object. There may be changes.

I am looking for an IC-910H. A member in a local club has one for sale.
What would be a fair price for it, it works and does not have 1.2G module.
Also any ideas on finding the 1.2 module and a fair price for it. I was

i bought one second-hand from a swap and shop website several years
ago and paid around $1000 CDN for it (about $750 USD). I've been
quite satisfied with it for satellite work.

AMSAT-Deutschland e.V.? and the Bochum Observatory are part of ESA?s
current education iniative.
On May 16, 2018, the newly founded European Space Education Resource
Office (ESERO) in Germany, or ESERO Germany for short, was officially
launched at a ceremony at the Bochum Planetarium. So far there have been
11 such ESERO offices in 13 different European countries - Germany was
not yet there. After a lengthy selection process, Bochum was finally
selected as the location for Germany. In cooperation with the
Ruhr-University Bochum, the Bochum Observatory, the AMSAT-DL and other
partners are founding members of this educational and scientific consortium.
This is a joint project of the European Space Agency ESA, the German
Aerospace Center DLR and other partners with the core objective of

Subject: [amsat-bb] Antennas used for AO-92 L/V, & a comment about
AO-92 this morning...

Hi!
It has been almost 4 months since AO-92 was opened up for general use, and
the first L/V activation. I have tried to work the L/V configuration anytime
it is active, whether I am home or away from home. I have worked
approximately
20 different stations over this time. Most of the time, I have used a
5-element
Comet CY-1205 Yagi with my Alinco DJ-G7T HT for my 1.2 GHz uplink.
Sometimes,
I go with a Chinese-made 10-element Yagi I ordered from an eBay seller.
>From working different stations across the country, it seems like other
stations
I work are using larger antennas than mine - maybe the same 10-element Yagi
I
use, the 16-element Comet CYA-1216E Yagi, Yagis with more than 16 elements,
or
some have used a helix. My question is this: other than the HT duckies used
by
a couple of stations early on, does anyone besides me use an antenna
smaller
than a 10-element Yagi to work AO-92 L/V? If so, what are you using? I am
not
so concerned about transmitter power, as there are a few of us using HTs
with
1W output on the 1.2 GHz band, and we are able to work AO-92 at that power
level.
A comment about the AO-92 pass around 1625 UTC this morning...
This was not a high pass out here in Arizona, with maximum elevation around
13
degrees to the east. I have worked stations to the east around this
elevation
in the past, so I went out to try for more contacts. Near the midpoint of
the
pass here, I heard a station make 2 long CQ calls on the pass. There should
be
no need to make CQ calls, let alone long CQ calls, on any FM satellite. The
145.880 MHz AO-92 downlink is easy to hear. There are ample opportunities
to
get this set up, by working other AO-92 passes in the normal U/V
configuration.
If the issue is getting the uplink frequency and/or antenna aligned with
the
satellite, full-duplex operation should ensure that there is no need for a
long transmission to be heard through the satellite.
If you want to hear the audio I recorded from this pass, it is in my Dropbox
space at http://dropbox.wd9ewk.net/ . Look in the Satellite_Audio-2018
folder,
and find the MP3 file with the name starting with "20180527-1626UTC47" for
the
recording.
73!

Hi Peter,
Thanks for sharing this update and good to see how space agencies like ESA
are associating with organizations like AMSAT to bring space science to the
classroms.This is good for our hobby as well.?

AMSAT-Deutschland e.V.? and the Bochum Observatory are part of ESA?s
current education iniative.
On May 16, 2018, the newly founded European Space Education Resource
Office (ESERO) in Germany, or ESERO Germany for short, was officially
launched at a ceremony at the Bochum Planetarium. So far there have been
11 such ESERO offices in 13 different European countries - Germany was
not yet there. After a lengthy selection process, Bochum was finally
selected as the location for Germany. In cooperation with the
Ruhr-University Bochum, the Bochum Observatory, the AMSAT-DL and other
partners are founding members of this educational and scientific consortium.
This is a joint project of the European Space Agency ESA, the German
Aerospace Center DLR and other partners with the core objective of
integrating space research into school programmes and thus promoting the

science, natural sciences and technology).

This is probably something you shouldn't click on. malware or something bad.
