BY70-1 CubeSat<\/p>\n<\/div>\n

A CZ-2D rocket carrying the amateur radio FM transponder satellite BY70-1 was launched on Wednesday, December 28 at 03:23 UT.<\/p>\n

Update: Paul Stoetzer N8HM<\/a><\/strong> reports working Wyatt Dirks AC0RA<\/a><\/strong> through the FM transponder during the 1709 UT pass on December 28. Paul says “Uplink requires precise frequency adjustment and there’s a delay on the downlink, but the signal is strong”<\/em>. A recording of the transponder can be heard at https:\/\/soundcloud.com\/paul-stoetzer\/by70-1-1706z-28-dec-2016<\/a><\/p>\n

The launch from the Taiyuan Space Launch Center was planned for December 26 but postponed due to adverse weather. It had been planned it would go into a 530 km circular Sun-Synchronous Orbit (SSO) but instead the orbit appears to be 524 x 212 km which will give an orbital lifetime of just one or two months.<\/p>\n

BY70-1 is a 2U CubeSat project for school education and amateur radio. It features 3-axis stabilization and deployable solar panels. In addition to the FM transponder BY70-1 has a camera and it is planned to download images and telemetry via a 9600 bps BPSK downlink.<\/p>\n

The IARU amateur satellite frequency coordination pages list these frequencies:
\n\u2022 145.920 MHz uplink
\n\u2022 436.200 MHz downlink
\nA 67 Hz CTCSS (PL Tone) is required.<\/p>\n
