Amateur Radio transponders on planned Chinese satellites to include HF

China's Amateur Radio Satellite organization, *CAMSAT*, has released some
details of three new Amateur Radio satellites that could be launched as
early as September. Two of the satellites, CAS-5A and CAS-6, will carry
transponders, and one of them will have HF capability.

*CAS-5A* is a 6U CubeSat. It will have an HF/HF (21/29 MHz) mode linear
transponder; an HF/UHF (21/435 MHz) mode linear transponder; an HF CW
telemetry beacon; VHF/UHF mode linear transponder; a VHF/UHF mode FM
transponder; a UHF CW telemetry beacon, and UHF AX.25 4,000/9,600-baud GMSK
Telemetry. Transponders will have 30 kHz passbands, except for the H/U
unit, which will be 15 kHz.

The tiny *CAS-5B*, weighing 1/2 kilogram, will be deployed from CAS-5A in
orbit. It will carry a UHF CW beacon on an Amateur Radio frequency. It will
be placed into a 539 x 533 kilometer, 97.5-degree orbit.

CAS-5A/B will launch from the Jiuquan Satellite Launch Center.

*CAS-6*, a 50-kilogram microsat, will include a VHF CW telemetry beacon; a
U/V mode 20 kHz linear transponder, and AX.25 4,800-baud GMSK telemetry
downlink. It will also carry an atmospheric wind detector and other systems
that will operate on non-amateur frequencies.

A launch at sea is planned for CAS-6 from the China Academy of Launch
Vehicle Technology. The microsat will be placed into a 579 x 579 kilometer,
45-degree orbit.

AMSAT has applied to the International Amateur Radio Union (IARU) to
coordinate frequencies for all three spacecraft
