Hej,
Idag kunde inte undertecknad vara med på HF nätet så jag vet inte
hur det avlöpte.
Jag postar några intressanta nyheter
ändå.
*Kina kommer nu med en amatörsatellit
http://www.amsat.org/amsat-new/satellites/satInfo.php?satID=116&retURL=satellites/futures.php
To
celebrate the launch of China’s first amateur satellite, XW-1,
AMSAT-China
will set up a special event station in Taiyuan, Shanxi
Province of China
using the callsign BT3WX. The station plans to
operate on all HF amateur
bands from 10 to 160 meters and on VHF/UHFamateur satellite bands, including
FM, SSB, CW, RTTY and PACSAT modes.
Operations at BT3WX have already
commenced and the special event
station will remain active until XW-1 is
launched. A specific launch
date has not been released as of press time, but
is expected in
mid-December.
A team of 200 participants will consist
of radio amateurs from all
around China, teachers and students, the State
Radio Regulation Bureau of China, the China Association for Science
Technology, the Chinese Society of Astronautics and the Chinese Radio Sports
Association officials, as well as journalists will participate in the
operation of BT3WX. Their goal is to inspire enthusiasm for amateur radio
satellite communications activities in China among radio amateurs and young
people learning satellite communication technology and space
knowledge.
THE BT3WX operating team is as follows:
Team leader: BA1EO,
Fan
Operation and Technology support: BD5RV, Michael Chen
Press release
and QSL Manager: BA1DU, Alan Kung
(P.O.Box 8091, Beijing, CHINA
100088)
The operators include BA4RB, BA4RN, BA4RS, BA4RX, BA4TA,
BA4TB,
BD4IBW, BD4REB, BD4RPJ, BD4XX, BH4REQ, BA6AA, BD6BW, BA7CK,
BA7JG, BD7PZL.
The equipment at the HF Station includes an Icom
IC-756PROIII and
IC-7000. The HF antennas are:
160/80M Ground
Plane
40M 3ele Yagi
20/15M 5ele Yagi
10M 3ele Yagi
WARC Ground
Plane
Power Amplifier: GO-2KW
At the Satellite station the gear will
include an Icom IC-910H
feeding a VHF 7 element cross Yagi and UHF 13 element
cross Yagi.
BT3WX Communications HF Award:
Stations completing two-way
communications with BT3WX on 9 different bands and modes can apply for the
BT3WX HF communications award. The same band in different modes counts as a
different band / mode.
BT3WX Communications Satellite Award Stations
completing two-way communications with BT3WX through at least two different
mode of transponders can apply for the BT3WX satellite communications award.
The different modes can be through the same satellite.

har försökt att titta lite på en möjlig bana för
satelliten (Viss
reservation tills vi får mer information från Amsat Kina)
(Från
Amsatlistan)
Very unscientific I just used FENGYUN 3A and modified
the
Mean Motion to 13.19 orbits per day.
Then the height becomes approximately
1200 km.
As far as I can find out, FENGYUN 3A was sent up from the
same
spaceport as XW-1 will be.
I used NOVA for Windows. It allows the
change without complaint 🙂

Kommentar från SM7WSJ (Lite
spekulationer)
Det här borde betyda att den har en bana något lägre än
FO-29 men nästan dubbelt så hög som VO-52. (Om det här fungerar så kan det
bli en riktigt fin julklapp från landet i öst.)
