CHINESE BIRD VERY ACTIVE (XW-1 Satellite News) [复制链接]

chinese bird very active (xw-1 satellite news). the new chinese satellite
xw-1 (hope-1) was in the linear transponder mode over south and north
america on december 20th, between 0222z and 0246z for the first time.
the passband was filled with stations over the u.s. with excellent signals.
k8yse reported making 13 contacts on this pass.
xw-1 is at an altitude of 1200km, more than 400km higher than the popular
ao-51, so-50 and ao-27 satellites. this means a longer visible pass and
more distance. contacts with europe are possible with the eastern us.
xw-1 will be in the fm mode between 0153 and 0228z, december 21st over
south and north america for the first time. one watt of output power makes
this satellite easier to hear, so many are expected to be making contacts
on this pass. a recording of the ssb pass can be downloaded at:

the fm pass will eventually be uploaded to the following file:

congratulations to the chinese team that designed, built and launched
this satellite. details can be found on the amsat web site at:

也充滿了對 ba1du bd5rv 的稱頌之聲.... :)

4rf 趕緊跳槽到衛星園地吧.....

别想拖我下水，我楼顶没地方架天线了，你不知道大陆现在房子有多贵吗？

听说陈版主正在向xw-1 dxcc进军。

很難, 在中國境內透過 xw1 能通聯的領域不超過五十個....

努力阅读中。哈哈。

为全世界ham带来的希望之星。

xw-1 ssb transponder activated over na

xw-1 ssb transponder activated over na

the first activation of the xw-1 linear transponder over north america took place in the early hours of dec 20 and drew ko4ma produced a spectragram of the event showing the 50 khz passband full of ssb signals.

on the amsat bulletin board he writes:

that was some really exciting stuff! i recorded the pass on my sdr-iq/r7000, and had the receive antenna split off to my normal station as well. right after turn on, k8yse responded to my cq, and we had a few brief exchanges. about that time i realized the middle of the pass band was going to be a bad place to be and moved up to the high end of the passband.

after moving up out of the mess, i worked w4dfu at the university of florida, with jay and jimmy at the helm, then hk4mke, andrew in columbia. signals were good until the end of the pass when i think i was having some polarity fades on my fixed lhcp antenna. 1 to 5 watts was plenty on the uplink, even when crowded. i use a 10 element horizontal only yagi for the uplink.

is a screenshot of from spectravue before tca. notice the lost ditter almost twice as strong as everyone else. there are also at least 9 separate ssb signals in that screengrab, and the beacon is at the far right. the whole file is about 680 mb. if anyone wants it, please contact me. we can exchange it over skype, or i'll burn it to your cd/dvd with an sase. spectravue is a free download, and well worth trying even if you don't have an sdr.
