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 145/435 MHz FM Transponder CubeSat
CAS-2T and another satellite with an amateur radio payload, KS-1Q (436.500 MHz), are attached to the final stage of the CZ-11 rocket. The final stage was originally expected to be in orbit for up to 30 days before re-entering the Earth’s atmosphere but reports indicate the orbit is 504 x 1030 km which could give an orbital lifetime of years.

The CAS-2T FM transponder does not appear to be fully functioning, see the report of Daniel Estévez EA4GPZ / M0HXM at http://destevez.net/2016/11/some-measurements-of-cas-2t-on-orbit-25/
KS-1Q like CAS-2T is also attached to the final stage of the CZ-11. It is reported to be a 1U CubeSat with a technology and launch vehicle monitoring payload.

H-II Transfer Vehicle KOUNOTORI
Mineo Wakita JE9PEL reports on the AMSAT Bulletin Board that six satellites with amateur radio payloads are to be launched to the International Space Station in December.
JAXA announced to the public November 7 that seven nano satellites are to be installed in H-IIB Transfer Vehicle “KOUNOTORI” (HTV) to be launched in December. Satellites are only about 1U~3U in size and will conduct experiments aimed at realizing the space elevator which is expected to facilitate the movement of Earth and Universe in the future. It’s the first time to launch in JAXA with seven satellites at a time.
HTV6 Launch: 1326 UT, Dec. 9, 2016 at the Tanegashima Space Center, Japan.

Radio amateur Andy Filo KJ6ZGI has been announced as winner of the ISS Design Competition organised by component distributor Mouser.
Tech Crunch reports nearly 250 ideas were submitted, everything from tools to toys to scientific instruments. The proposals were vetted and submitted for judgment by tech-savvy astronaut and former ISS resident Col. Chris Hadfield VA3OOG, and Grant Imahara, of Mythbusters fame.
Andy’s winning entry was for a 3D printed “mothership” to launch Femosats into space. Femtosats are 30mm square and 4mm thick self contained satellites that extend the Internet of Things to Space.

Sandringham students used amateur radio to talk to Tim Peake GB1SS on the ISS
The Watford Observer newspaper reports that Sandringham School students’ amateur radio communication project gave them the opportunity to visit the UK Parliament at Westminster.
The Observer says: Four students from a St Albans school showed off their engineering prowess to politicians, policy makers and businesses in Parliament.
The Year 9 and 11 students from Sandringham School, on The Ridgeway – Sandy Cairns, Polly Gupta M6POG, Stanley MacMurray and Emma Wilkinson M6GJQ – were invited to the event on Monday [Oct 31] after impressing judges with their engineering project at the regional heats of The Big Bang UK Young Scientists and Engineers Competition
Their amateur radio communication project saw them set up a radio to speak with Tim Peake while he was aboard the International Space Station.
Rhian Kazwini, Head of Science at Sandringham School, said: “Entering the competition has been great fun and given the team an idea of just how interesting a career in engineering could be.”

The reports from the RSGB Spectrum Forum meeting held October 29, 2016 have been released. The VHF Spectrum Report highlights the 12 dB increase in Noise Floor.
The report, produced by the RSGB VHF Manager John Regnault G4SWX, notes that Ofcom have increased the noise floor criteria used to calculate coverage areas for Low Band VHF from -104dBm to -92dBm. This recognises the increase in human-generated noise in this part of the spectrum.
The increase in Noise Floor level means you now need 150 watts to achieve the coverage once obtained with a 10 watt transmitter.

HFsat concept of operations
US Naval Academy students are planning an amateur radio CubeSat HFsat carrying an HF transponder as well as 2m APRS.
They are working with Bill N6GHZ on the HF transponder card which will provide a bandwidth of 30 kHz, the frequencies are currently 21.4 MHz uplink and 29.42 MHz downlink. Doppler shift will be reduced to less than 2 Hz per second by using an inverting transponder.
The satellite will be gravity gradient stabilized by its long full size 10 meter band halfwave HF dipole antenna with tip masses
