New XW-2 satellites – linear transponders active

Information below is from AMSAT-UK


Nine XW-2/CAS-3 amateur radio satellites were successfully launched on Saturday, September 19, 2015 at 23:01:14 UT on Beijing’s new Chang Zheng 6 (CZ-6) rocket from the Taiyuan Satellite Launch Center.

Six satellites (designated XW-2A to XW-2F) carry 435/145 MHz U/V linear transponders for SSB/CW communications, LilacSat-2 (CAS-3H) has a V/U FM voice transponder and APRS. The other two satellites DCBB (CAS-3G) and NUDT‐Phone‐Sat (CAS-3i) only have telemetry downlinks.

The frequencies to be used by the satellites are here. Some satellite frequencies fall outside the international amateur satellite bandplan, so please be aware of local terrestrial users.

camsat-cas3a1David Bowman G0MRF reported “Good signals from CAS3-F at 07.00 UTC  over Europe. Managed QSOs with SP5ULN in KO02  and F1AFZ in JN17 using the special event station at GB0RWC (Rugby World Cup).”

MTN Global’s latest brand commercial tells the story of a little boy who discovers, via MTN’s world class internet, that it is very simple to build a homemade radio that will allow him to actually speak to an astronaut in space. He tries and fails and tries again, using the New World of MTN to embark on a journey of discovery that takes a rather unexpected turn. Because that’s the thing about discovery, there’s always more to discover.

CW Field Day Message on 630 meter band–474 khz

Greetings Cowtown club!  I wanted to extend this on-air demo opportunity to you and your group at Field day!
Starting with Field Day 2013, I transmitted a CW field day message on the 630-meter band for demonstration purposes to stations around the Texas area.  Let me be clear that this was not the ARRL’s Field Day message.  I hope to do it again this year, weather permitting, and wanted to let you know about it since I know you have low band enthusiasts out that direction.  Last year’s operation was amazingly successful and the message was copied as far away as Salt Lake City, Utah, using rigs and antennas set up for ham bands at a Field Day site.  All this was done with 1 Watt ERP and a short base-loaded vertical!
The plan will be to run the message on 474 KHz CW starting Saturday morning, June 28, around 8am and it will run through the end of Field Day on June 29, sometime after 1pm CDT.  I hope to run it at 15 minute intervals starting at the top of each hour and expect the message to run 5-10 minutes in length.
In addition to my station, there will be other Part 5 experimental stations around the US following suit with their own messages.  Below is a list:
WG2XKA in VT         472.5 Khz CW
WG2XJM in PA         473 KHz CW
WD2XSH/20 in OR    475 KHz CW
WG2XIQ in TX           474 KHz CW
So why do this?  We are hoping to show the value of the band, both in groundwave and skywave coverage.  The groundwave signals will outperform anything we have available to us under part 97 and the skywave, particularly during the winter, will surprise you, often times being reported thousands of miles from the transmitter site (I was heard in Europe and Alaska quite often last winter and make regular coast-to-coast QSO’s on CW and digital modes on 630-meters).  There are so many misconceptions about what goes on below the AM Broadcast band and we hope to provide opportunities for individuals at their club’s field day operation to experience the band first hand. Summer is not the best time to do this, but week keep signals on the band all year long and make QSO’s all year long.
Whatever antennas and rigs you might have hooked up for your operation, simply tune them to one of the frequencies above and see what you hear.  Again, I will be on 474 KHz CW and plan on running at a 15 minute interval if everything works out.
If you have any comments or questions, please feel free to contact me directly via email.
73 and I hope your group has a wonderful Field Day 2014!

PS:  I *may* offer a certificate to those that report my signal around the Texas area so reports, whether copied by ear or software are very welcome!
