Two New Satellites of Note

Ive never been a big satellite guy, but Im beginning to think that Im
missing something by not trying it. Here are a couple of ham satellites
that caught my eye recently:

First ever D-STAR satellite to be launchedÂ*April 22

The ARRL reports that the first-ever satellite to carry a D-STAR (Digital
Smart Technologies for Amateur Radio) Amateur Radio payload into space is
expected to launch on April 22 from Guiana. Built by students at the
University of Liege in Belgium (ULg), Â*the Orbital Utility For
Telecommunication Innovations (OUFTI-1) will be the first satellite to
carry a D-STAR transponder. OUFTI-1 CubeSat is one of three CubeSats
developed by student teams under the European Space Agency (ESA) Education
Office “Fly Your Satellite!� program, which is aimed at training the next
generation of aerospace professionals. The satellites arrived in South
America on March 25, followed by the student teams a few days later.Â*The
CubeSat’s frequencies are 145.950 MHz (FSK AX.25 and D-STAR down, with an
uplink at 435.045 MHz. OUFTI-1 will carry a CW beacon transmitting on
145.980 MHz.
The SkCube is Slovakias first satellite.

Slovakia to send up its first satellite

Being Slovak-American, this item was of interest to me.Dan

Physics.Org reports thatÂ*Slovakia will launch its first
satellite—SkCube—into orbit in June atop the SpaceX Falcon 9 rocket from
Cape Canaveral Air Force Station in Florida. SlovakiaÂ*is one of the last
countries on the continent to have its own satellite.

SkCUBE will focus on ham radio experiments that will allow amateur radio
operators to communicate via the satellite. It will also transmit telemetry
data via Morse code and high speed data and image transmission via the 2.4
GHz band. Radio amateurs from all over the world will be able to receive a
picture, which will be stamped with the skCUBE name, the call sign OM9SAT
and a timestamp. Details on how to use the satelliteÂ*will be published in
advance on the projects website.

The satellite will also include a VLF receiver with a frame magnetic loop
antenna that Â*allows recording of radio signals in the 3 to 30 kHz range.
The data will be publicly accessible for those who are interested.
