I wish to inform you all that the first 3B8 satellite project, MIR-SAT1 is moving in the right direction as follows:
1) A WEB site is now available (in spite in its infancy): https://spacemauritius.com <https://spacemauritius.com/>, it has a HAM page (to be populated).
2) 3B8 Radio Amateurs are deeply involved with the project and this has already created a new generation of potential HAMs, some 7 (+/-) more candidates taking the exams in beginning May with at least 5 only due to the “bird”. In spite the figure may seems low, there are only about 20 active OM’s in 3B8, thus actually a relative huge progress in terms of potential HAM population.
3) The first secondary school (college) has built a receiving ground station last week and already received their first LEO's signals. This is a pilot project which will be extended to many schools in the coming months and surely create motivation for hundreds of students to become HAMs, hopefully we will see the HAM population grow exponentially in the coming months (this is my personal goal).
4) This project has the full support of the Mauritius Government and fully financed by the Mauritius Research Council which is a non-profit organization for the development of science and technological innovation.
5) The satellite will be launch by JAXA end this year from the ISS.
6) The final design is being finalized and details will be in shared to all on above mentioned WEB site.
7) IARU coordination will be applied for shortly, as soon as the final design completed.
I would eventually request the HAM community to help us to collect Telemetry when the “bird” launched by end of this year, will keep you informed.

No big issue, just curious if anyone has experienced this.
Now that FalconSat3 is back in Eastern US in late evening before 10PM EDT,
36 minutes earlier every day as Bob pointed out, I'm trying to work aprs
Before, following these excellent guides
and http://andrewbnortham.com/ke8fzt/falconsat/ I had success.
Then something happened and my TH-D72a just sits there after pressing
"BCON" with "STA" on the screen waiting - I have ensured, doubled checked,
both A&B if that matters, downloaded with MCP and "Ignore DCD" is the
setting, but it sure acts like it is ON!
Having lots of luck decoding with direwolf, but my handset just won't
transmit when signal is good :\
This article was written by a ham and is about hams contribution to radio astronomy.
https://www.nrao.edu/whatisra/hist_ham.shtmlI think if he was a ham operator, it would have definitely been mentioned in the article.
Side note... daughter and I got to visit the VLA in New Mexico back in 2016. (The Karl G Jansky Very Large Array - named for him) The size and scale of the place is just amazing, pictures don't do it justice. But I do have a couple pictures posted on my rover profile page that were taken while there. One of me 'wishing' I could hook up an HT to a dish and one standing at the foot of a dish. It dwarfs me completely... those dishes are two school bus lengths across! https://www.qrz.com/db/N4UFO/P
Hello AllKarl Jaskey is the father of radio astronomy . Was Karl Janskey a licenseamateur if so what was his call sign?Tnx nick de k5qxj
Each year South Bay Amateur Radio Association (SBARA) hosts a "Radio In The Park" event, at Fremont Central Park.
The event attracts both hams and public alike and runs generally from 10am to 4pm. Several portable stations are setup and operated, like a tailgate party.
I plan to setup a portable satellite station with a tripod and plan to work the FM birds at that time. We will be encouraging and helping hams in making their first satellite contact.
I'm sure the passes will be quite busy on Saturday, but please look out for operators from CM97.
Thanks in advance.
Fremont, CA [CM97]
I have an IC-820H on loan till I can afford my own rig. On it you engage
the CTCSS tone with a button, but as soon as you turn the tuning knob it
disengages the tone. This makes it impossible to use Gpredict to control
the doppler shift. Anyone who knows how to make the tone continuously
73 from Taiwan.
Thanks for that.
Just added QO-100 to the list. (same link).

PHL-Microsat Issues Diwata-2 Amateur Radio Unit Service Announcement
On April 26 Philippines PHL-Microsat announced that Diwata-2's ARU
or ham radio is now ready for service.
While Diwata-2 is classified as an Earth-observing microsatellite -
with 4 optical payloads or cameras tasked to gather data from space
in the form of satellite images - it also carries an Amateur Radio
The ARU introduced in Diwata-2 is a spaceborne module designed and
manufactured in the Philippines. It is targeted for amateur radio
communication, emergency and disaster response, and wireless experi-
mentation and training. Operating modes will include:
+ FM voice repeater
Uplink: 437.500 MHz FM (CTCSS 141.3)
Downlink: 145.900 MHz FM
+ APRS message digipeater
Uplink: 437.500 MHz 1K2 AFSK
Downlink: 145.900 MHz 1K2 AFSK
By default, the ARU will operate as an APRS digipeater once a
week on Sunday and can be changed as necessary via command link.
+ Morse-based beacon
Downlink: 145.900 MHz
+ APRS-based beacon
Downlink: 145.900 MHz 1K2 AFSK
The ARU will send different beacon formats according to its scheduled/
announced operation. Morse-coded CW beacons are sent when ARU
operates as FM voice repeater. Morse-coded CW beacons will be
transmitted on a 2 minute cycle with 1 minute of transmission
followed by a 1 minute pause.
APRS beacons are sent when it operates as APRS digipeater. APRS
beacon packets will be transmitted every 30 seconds, with a packet
duration of 1-2 seconds.
For schedule updates, follow @Diwata2PH on Twitter or
via the publicly accessible web page at: https://twitter.com/Diwata2PH
On April 11, the Radio Amateur Satellite Corporation (AMSAT) desig-
nated Diwata-2 as Philippines-OSCAR 101 (PO-101).

Coronation Station HS10KING/mm On Geostationary Satellite
To mark the Coronation of King Vajiralongkorn
Bodindradebayavarangkun (King Rama X) from May 4-6, 2019 the Radio
Amateur Society of Thailand under the Patronage of His Majesty the
King will be operating a special event station
The station will be operated from the Royal Thai Navy aircraft
carrier, the Chakri Narubet, in the Gulf of Thailand from May 3-6
using the callsign HS10KING/mm.
This station will be making QSOs in the 40, 20, 15 and 10 metre HF
bands, on 2 metres VHF and also using amateur radio satellites,
including the Es’hail-2 / QO-100 satellite.
Consequently, the May meeting of RAST will be postponed to the
second Sunday of the month, and will take place on Sunday May 12 at
Sena Place Hotel when applications to take the upcoming Intermediate
Class examination will be available
As usual all RAST members are welcome to attend this meeting and
hopefully they will be able to have a QSO with HS10KING/mm.

AMSAT South Africa Developing AfriCUBE SDR-based CubeSat
AMSAT SA has announced that parallel to its analogue Kletskous Cube-
Sat, the group is working on a digital project featuring a Software
defined transponder. Called AfriCUBE, the CubeSat will use the same
space frame as KLETSKOUS. Anton Janovsky is current building a proto-
type transponder. AMSATSA is inviting persons interested in becoming
part of the development team to send their details to:
Meanwhile the development and final construction of the AMSAT SA
KLETSKOUS is plagued by electronic component obsolescence. This
forces unwanted design changes to be made to ensure that when the
time comes to construct the final launch unit, the main components
are still available.
The KLETSKOUS team decided to freeze the design of KLETSKOUS and pur-
chase a quantity of devices to proactively mitigate future obsolesce.
This decision will also speed up the process of putting a final satel-
lite on the table. "Every time we change designs to mitigate for the
discontinued components, it is like starting the design a fresh,
creating new problems that have to be solved", Hannes Coetzee, ZS6BZP
said. "By freezing the design, in other words making a final decision
on the main specialised devices to be used, we will be able to speed
up the process of putting a flight ready unit on the table."
KLETSKOUS is not a textbook design. Most of the sub-components that
will make up KLETSKOUS are designed and being built by the volunteer
team. "We do not have the finances to go out and purchase sub-units
and simply wire them up.", Coetzee said.

See the coverage map for the APRS satellites on 145.825. There is a
hole in Central America where the telemetry from these satellites can
go for almost three full orbits and not be captured. All the rest of
the world is covered.

We'd like to fill that hole!
