Iceland/Greenland/Faroe Islands on Satellite July 4-19

Gabe Zeifman NJ7H/VE6NJH has finalized plans for an upcoming trip to
Iceland, Greenland, and the Faroe Islands. Once again, this is a trip
with family so radio is not his priority. However, he will put forth
my best effort to give these rare entities and associated grids to
everyone in range.

Gabe will be arriving in Iceland at about 0000Z on July 5 and spend
one night
at the hotel on the airport (access to HP83/84 line).

Gabe reports, “We will be in Iceland until July 10 with numerous
grids in the HP and IP fields possible, no strict plan yet.

“We will continue on to the Faroe Islands July 10-14. I will make an
effort to operate from both IP61 and IP62 while in the Faroes.

“Finally, we will head to Greenland on July 14th staying until the
18th. The destination in Greenland is Ilulissat in GP49. I do not
anticipate any other grids to be activated in Greenland, although if
there is an opportunity I will, but I don’t expect any opportunities.
>From GP49 all of North/Central America and Europe should be in range,
along with portions of South America, Asia, and Africa, much of it
even possible on SO-50. I anticipate a nearly perfect horizon to the
west.

“On the 19th we travel back to the US with a several hour connection
in Iceland. I will also have two nights on the beginning and end in
New York City, and July 21-25 in Florida (anyone who needs EM90, hit
me up).

“In exciting news, this very well may be the last DX use of NJ7H.
Don’t worry, I am not retired from roving. I am beginning my training
at the FAA as an air traffic controller on July 26th and will be very
busy with that. I expect facility placement in late October, and I am
requesting Alaska. Although I cannot yet be certain, I have been told
that I should expect to receive my request.

“QSLing for this trip will be via LoTW. I still need to get some new
generic cards printed, but if you need paper I’ll get cards printed
eventually, just don’t expect rush service (I have some from other
trips in the backlog, don’t worry I havn’t forgotten).”

Calls to be used:

Iceland: TF/NJ7H
Greenland: OX/NJ7H
Faroe Islands: OY/NJ7H

LilacSat-1 släppt från ISS

Satelliten LilacSat-1 är nu släppt från ISS i samband med QB50-projektet. LilacSat har en mer avancerad amatörradio ombord jämfört med de andra satelliterna.
Läs mer på denna länk: http://lilacsat.hit.edu.cn/?page_id=594

Info:

The FM transponder is expected to be a popular mode using amateur
radio FM walkie-talkies or mobile radios. The voice filter passband
is in the range of 300~3500 Hz. Below 300Hz below the sub-audio in
the form of baseband data emplying a CCSDS mode of 300 bps telemetry
data transmission.

The BJ1SI-1 APRS digipeater will immediately forward the received UI
frame in real-time.

The BJ1SI-2 APRS digipeater will allow delayed forwarding with a
user specified forwarding path and an ASCII coded time delay.

Uplink
——-
+ Frequency 145.985 MHz PL 67
+ Antenna 1/4 wavelength monopole, linear polarization
+ FM repeater Analog voice, no PL
+ APRS Digi AX.25 UI 1200 bps AFSK

Downlink
——–
+ Frequency 436.510 MHz
+ Callsign BJ1SI
+ Antenna Turnstile
LHCP (Forward, main lobe)
RHCP (Backward)

+ Telemetry CSP/CSP + AX.25 UI (Cube Satellite Space Protocol) was

ISS NRCSD#1 Cubesat Deployment

I dagarna (maj 2017) har det kommit ut ett antal nya Cubesats från ISS. Flera lyssnarrapporter har kommit redan. Det finns en video på utsläppet från ISS  här.

DK3WN Satblog har en aktuell status daterad 18 maj.

DK3WN har gjort några utmärkta frekvens-skisser över satelliterna:

 

Och från utsläppet den 18 maj följande:

 

Fler länkar och info finns nedan, från AMSAT-UK:

The second phase of QB50 CubeSats should be deployed from the
International Space Station over three days from May 23-25, 2017.

Built by university students and research organisations from 23 c
ountries around the world, the QB50 constellation aims to study the
lower thermosphere 200-380 km above the Earth.

11 QB50 CubeSats were deployed in the first phase and a further 17
will be deployed in the second phase. The beacons should be
activated about 30 minutes after deployment.

The QB50 CubeSats have downlinks between 435.7 and 438 MHz and
reports from radio amateurs are most welcome. Beacon data received
can be uploaded to a dedicated QB50 webpage at
https://upload.qb50.eu/

LilacSat-2 (ON02CN), which deploys at 0815 GMT on Tuesday, May 23,
is carrying a FM to Codec2-BPSK Digital Voice transponder, an APRS
digipeater and camera. Further information at
https://amsat-uk.org/2017/05/19/lilacsat-1-cubesat-iss/

Two of the ISS QB50 CubeSats deployed in the first phase, ON01FR
437.020 MHz and ON05FR 436.880 MHz, carry V/U FM transponders.
The uplink frequency for both is 145.860 MHz with 210.7 Hz CTCSS, see

AMSAT-SM 35 år den 24 april 2017

Den  24 april 2017 är det 35 år sedan AMSAT-SM bildades på årsmötet SSA Oskarshamn! SM5IXE Thomas Johansson var föreningens första ordförande och ni kan läsa de första raderna vid bildandet nedan. Första numret av AMSAT-SM INFO kan ni även läsa här.

Jag har själv varit medlem i AMSAT-SM runt 25 år och har sett många “versioner” av föreningen. När vi var som mest aktiva fanns det en försäljningsfunktion, minst fyra nummer av medlemstidningen INFO gavs ut varje år och jag tror det var över 400 betalande medlemmar.

För ett par år sedan tog styrelsen beslutet att anpassa verksamheten till rådande miljö för amatörradioföreningar i stort. Vi förenklade så mycket som möjligt, la officiellt ner medlemstidningen, slopade tillfälligt medlemsavgiften och skapade en inriktning som en informerande förening. Och jag tror att AMSAT-SM i nuvarande form kommer att finnas i många år till!

Följ med oss i framtiden bland nya spännande satelliter!
