After being postponed several times, nine Chinese satellites carrying Amateur Radio payloads were launched on September 19 at 2300 UTC, separating from the Long March launch vehicle about 15 minute later. China Amateur Satellite Group CAMSAT CEO Alan Kung, BA1DU, said that four of the microsatellites and two of the CubeSats included in the launch have been designated as XW-2A through XW-2F. The other three satellites — a CubeSat, a nanosatellite, and a picosatellite — carry the designations CAS-3G through CAS-3I, respectively. All of the new satellites have downlinks on 2 meters and uplinks on 70 centimeters. Satellite enthusiasts have been enjoying the sudden surfeit of spacecraft to work.
“So many signals, so little time,” was the observation on the AMSAT-BB from Alan Biddle, WA4SCA, who lives just south of Nashville.
“Very good copy on CAS-3 CW beacons on [XW-2] A, B, C, D, E, F. Strong!” Clayton Coleman, W5PFG, reported from Texas. Not long after launch time, W5PFG and fellow Texan Glenn Miller, AA5PK, worked each other via CAS-3F. He reported the CW beacons were strong on all of the CAMSAT satellites. The CW beacons carry individual call signs for the satellites as well as telemetry in the form of three-character text groups and the word “CAMSAT.”
Edward Chuang, BX1AD, in Taiwan, posted to the AMSAT-BB the text he copied on September 20 at 0938 UTC from XW-2A through XW2-F:

The satellites also have been heard in Europe. “Good signals from CAS3-F at 0700 UTC,” reported David Bowman, G0MRF, who was at the Rugby World Cup special event station GB0RWC. He reported contacts with SP5ULN and F1AFZ.
The XW-2 satellites also have been heard in South America and in Southeast Asia. “I received CW beacon from XW-2 during 1108 UTC pass, including CAS-3A, CAS-3B, CAS-3C, and CAS-3D, maximum elevation 72° over Bangkok, Thailand,” Karn Suwanrat, E20ZFD/AA1AF reported on September 20. He has posted a YouTube video.
“Wow, impressive to see all six satellites via SDR on a 4° degree pass,” enthused Mark Hammond, N8MH, in North Carolina. “Bravo, CAMSAT and Alan! Congratulations on a wonderful start of mission.”
