AMSAT-UK and AMSAT-NL working with ISIS BV are delighted to announce that
the FUNcube 435/145 MHz SSB/CW transponder, on the 2U CubeSat QB50p1
(EO79), has now been activated with a regular schedule.
Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified over the
forthcoming weeks as a result of experience.
The transponder frequencies a
Uplink: 435.047-435.077 MHz LSB
Downlink: 145.935-145.965 MHz USB
The output power is approximately 400mW.
Qb50p1 (EO79) was launched in June 2014, as a collaborative effort led by
the von Karman Institute and ISIS-BV, into a sun synchronous 620600 km
polar orbit as a precursor spacecraft for the QB50 mission. The primary
function of the satellite was to test a number of the systems and science
payloads. This phase has now been completed and we are grateful to VKI and
ISIS BV for carrying this transponder into space and, again, to ISIS, for
developing and uploading the new, required, flight code.
We hope you have lots of fun using EO79!

CAS-2T a technical verification satellite for CAMSAT CAS-2 series amateur
radio satellite launched at 23:42 UT November 9, 2016 on a CZ-11 rocket.
The 2U CubeSat, developed by students from Fengtai District, Xicheng and
Haidian District secondary schools, carries a ham radio 145/435 MHz FM
transponder. CAS-2T will not be separated from the final stage of rocket,
so the orbital life may be 10 to 30 days before the final stage of the
rocket re-enters the atmosphere.
