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

Quoting Wei BG2BHC:
"Can you help to find amateurs in the US to help to monitor DSLWP-A
and 436.425 now?  We lost the contact of satellite A on S band after
adjustment.  We just tried to switch on UHF, but we don't know if it
works or

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

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
437.225 MHz, a telemetry beacon at 435.325 MHZ, and a linear
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.

ARLP022 Propagation de K7RA

Propagation Forecast Bulletin 22  ARLP022
>From Tad Cook, K7RA
Seattle, WA  June 1, 2018
To all radio amateurs

ARLP022 Propagation de K7RA

On May 30 at 0005 UTC the Australian Space Forecast Centre issued a
warning: "On 1 June geomagnetic activity is expected to increase to
Active and Minor Storm levels due to arrival of the co-rotating
interaction region and high-speed solar wind streams associated with
the recurrent trans-equatorial coronal hole."

On May 31 http://www.spaceweather.com issued this Solar Wind Alert:
"NOAA forecasters estimate a 60% chance of minor G1-class
geomagnetic storms on June 1st, increasing to 65% on June 2nd, when
a stream of high-speed solar wind is expected to reach Earth.  The
last time this gaseous stream lashed our planet's magnetic field,
almost a month ago, it sparked bright ribbons of purple light
(a.k.a. 'STEVE') seen from multiple US states. Visit today's edition
of http://www.spaceweather.com for more information."

The Sun remained active over the past reporting week. Average daily
solar flux rose from 70.1 to 74.9, and average daily sunspot number
rose from 7.7 to 26.3. During the previous week in which the average
daily sunspot number was 7.7, the first four days had no sunspots.

New sunspot regions appeared on May 21, 23 and 24.

Predicted solar flux is 77 on June 1-3, 76, 74 and 72 on June 4-6,
70 on June 7-8, 71 on June 9, 72 on June 10-14, 70 on June 15-17, 72
on June 18-23, 73 on June 24, 72 on June 25-30, 70 on July 1-6, 72
on July 7-11, 70 on July 12-14 and 72 on July 15.

Predicted planetary A index is 25 on June 1-2, 15, 12 and 8 on June
3-5, 5 on June 6-12, 8 on June 13, 5 on June 14-18, 8 on June 19, 5
on June 20-23, 8 on June 24-25, 5 on June 26-27, then 15, 28, 15,
12, 10 and 8 on June 28 through July 3, then 5 on July 4-9, 8 on
July 10, and 5 on July 11-15.

2018 ARRL Field Day is June 23-24. Assuming the predicted numbers
above, conditions should be good for Field Day. We want to see low
geomagnetic activity, and planetary A index at 5 and 8 on Saturday
and Sunday are good indicators. During this period of low solar
activity solar flux at 72 and 73 is also good.

Ted Leaf, K6HI of Kona, Hawaii reports that he is still in operation
through the local volcanic activity, and asks, "Are there beacons
for the lower frequencies, especially now with the lower solar

I found this Wikipedia resource for HF beacons:


Of course, there are lower frequency HF resources on
http://www.wsprnet.org, but this is a bit different than showing
what you can tune in and hear without using a special weak signal

Any readers have suggestions for lower frequency HF beacons?

Note that Ted has a comment on page 56 of the June 2018 QST
regarding preamps and attenuator effects on receiver noise.

>From last week: https://bit.ly/2LG8MAp

F.K. Janda, OK1HH brings us this geomagnetic activity forecast for
the period June 1-26, 2018.

"Geomagnetic field will be:
Quiet on June 11-12, 16-17, 20-23
Quiet to unsettled on June 10, 18, 24-25
Quiet to active on June 8-9
Unsettled to active on June 3-4, 7, 13-15, 19
Active to disturbed on June 1-2, (5-7, 26)

"Solar wind will intensify on June 1-3, (4-8, 13-15), 16-17, (18-19,

- Parenthesis means lower probability of activity enhancement.
- Forecasts remain less reliable."

>From Dr. Tamitha Skov, the Space Weather Woman:

"What's Old is New Again

"Dear Tad,

"I am still smiling at the huge response I got to a post I put up on
Twitter this week. A newbie to our Space Weather community dared to
talk about amateur radio as if it were an outdated hobby-- whoops,
bad idea. I gently educated him. In doing so, I roused many radio
amateurs and emergency communicators, who added their own comments
and talked about their own personal experiences in the field. It was
very gratifying. What I hadn't expected, however, was the strong
interest in the concept that amateur radio will be critical to
establishing over-the-horizon radio communications on planets like
Mars in the near future.

"This idea brings me back to how we managed to communicate over long
distances many decades before we had satellites, internet or
cellular networks. In terms of wireless communications on Earth, we
were very much in the same place back in the early 1900s that we
find ourselves in now when we think about colonizing Mars. Yet few
people realize that despite all our advanced technology, we can't
bring a cell phone to Mars. We will need to fall back on our 'old
ways' of doing things when it comes to communicating on other
planets. Isn't it funny how 'old' things become 'new' again?

"Speaking of, this week brings us a new chance for a decent solar
storm. Strangely though, the source of this storm is an old coronal
hole that gave us a moderate level solar storm about a month ago.
This old hole has survived its backside passage on the Sun and has
now returned, with the new promise of bringing aurora views down to
mid-latitudes again. Isn't it funny, what was old has become new
again, in more ways than one!

"Cheers, Tamitha"

Upcoming Binaryspace HAB Launch

Binaryspace is doing another High-Altitude
Balloon Launch from about 07:00 CAT on 9 June from the Leeukop Farm
Airfield in Deneysville in the Free State. Everybody is invited to
join us for the day to launch and chase the balloon. We are
estimating a 3-hour mission from launch to recovery. The Sasolburg
Amateur Radio Club (ZS4SRK) will join us with the tracking and
recovery of the payload. Flexible Use of Airspace has been approved
and depending on weather or technical difficulties, the launch and/or
the payload contents can change at any time.

We have some new equipment to test on Mission - Binary 03. A SSTV
Camera Transmitter (400 - 500 mW) will take a photo and transmit it
every 5 minutes. The call sign is ZR6MUG and will transmit on 144.500
FM, Martin 1 Mode and you will need MMSSTV to decode. A Telemetry
Transmitter (400 - 500 mW) will transmit telemetry data every 30
seconds under the call sign ZR6TG on 144.600 FM and you can use
FLdigi to decode. And an APRS Transmitter (300 mW) will transmit
position and altitude every minute on 144.800 MHz under the call
ZR6TG-11. We will also have a Go-pro camera and a Science Lab
(Raspberry pi based with lots of sensors) in the payload. The payload
is estimated to be around 900 g and we are using a 1 000 g white

There are several prizes and awards available. The first person to
recover the payload will get a prize and footage of the payload
coming down will receive a prize. Special awards will be given to
everyone who captures the SSTV images and RTTY telemetry. Please e-
mail the decoded information, time of transmission (bonus if you can
provide a recorded sound clip), your location and the equipment used
totvdbon @ gmail.com.
