LituanicaSAT-1 Camera and FM Voice Transponder
The LituanicaSAT-1 team have provide a further update on upcoming operation of the CubeSat’s FM transponder.
LituanicaSAT-1
Dear amateur radio operators,
The LituanicaSAT-1 FM transponder is scheduled to be operative again on May 1, from 9:30 UT to 14:00 UT.
Satellite’s ground control station in Vilnius will be monitoring the transponder’s frequency and attempt to call CQ with the amateur call sign LY5N (LituanicaSAT-1 callsign) when the satellite will be in sight of the ground station. The expected time windows are:
* 2014/05/01 10:46:22 UT – 2014/05/01 10:56:24 UT
* 2014/05/01 12:21:48 UT – 2014/05/01 12:31:47 UT
All QSO’s with the call LY5N will be granted special QSL cards, signed by the LituanicaSAT-1 core team members and sent out via bureau (no directs).
Every amateur working the FM repeater is encouraged (but not obligated) to RX and answer only the LY5N CQ call during the above time windows.
73,
LituanicaSAT-1 team
Frequency are approximately 435.1755 MHz for the downlink and 145.950 MHz for the uplink (+/- Doppler Shift).

KickSat Sprite satellites deployed – Image by Ben Bishop VK2FBRB
The British Interplanetary Society (BIS) are holding a meeting to prepare for reception of their fleet of Sprite satellites which will be deployed by the KickSat CubeSat on May 4 at 2000 UT.
437 MHz Sprite
Everyone is welcome to attend the meeting which takes place from 10 am to 4:30 pm on Saturday, May 3 at 27/29 South Lambeth Road, Vauxhall, London, SW8 1SZ.
The BIS events page says:
Dragon X has successfully deployed the KickSat CubeSat carrying 104 Sprites, a fleet of which were funded by the BIS and BIS members!

In preparation for the timed deployment of the Sprites from the CubeSat, the BIS KickSat team will meet at the BIS HQ with two goals:
• Ensure everyone with a ground station has a working installation of GNURadio
• Have some practice tracking other satellites
Present on the day will be radio experts, software experts, and a range of software defined radios and antenna.
Everyone is welcome to attend. Bring a laptop if you want help installing GNURadio.

KickSat Sprites – Radio Competition https://amsat-uk.org/2014/04/10/kicksat-sprites-radio-competition/
PI9CAM Dwingeloo 25 meter dish antenna
OPTICKS is a live radio transmission performance between the Earth and the Moon during which images are sent to the Moon and back as radio signals using the MMSSTV Slow San TV software developed by Makoto Mori JE3HHT. A live Google+ hangout is taking place on May 1 at 2000 UT. A Reddit AMA will precede the Hangout at 1500 UT.
The project has been realized by visual artist Daniela de Paulis (IT/NL) in collaboration with Jan van Muijlwijk PA3FXB and the CAMRAS radio amateurs association based at Dwingeloo radio telescope (NL). Each live performance is made possible thanks to the collaboration of radio amateurs Howard Ling G4CCH (UK), Bruce Halász PY2BS (Brazil) and Daniel Gautschi HB9CRQ (CH).
The live hangout will feature a “touch” and bounce of Humans in Space Youth Art Competition artwork off the Moon using OPTICKS radio wave technology. Guests and remote participants will discuss the significance of the artwork and the performance and explore the impact of past, present, and future human presence on the Moon.
Guests

OPTICKS makes use of a technology used by radio amateurs called Earth-Moon-Earth or Moonbounce in which the Moon is used as a natural reflector for radio signals.
In October 2009 Daniela de Paulis and Jan van Muijlwijk PA3FXB started pioneering a new application of Moonbounce technology, called Visual Moonbounce, which allows sending images to the Moon and back, combining Radio Astronomy with amateur radio technologies.
The title OPTICKS is inspired by Newton’s discoveries of the light spectrum, reflection and refraction. Similarly, the colours composing an image – converted into radio signals – are bounced off the Moon (reflected and refracted) by its surface during each live performance.
The performance is introduced by live sounds of amateurs radio signals captured by the Dwingeloo antenna tracking the moon.

Ofcom has published additional information on co-existence studies between 2.3 GHz Long-Term Evolution (LTE) and 2400 MHz Wi-Fi.
The ITU Amateur-Satellite Service allocation is 2400-2450 MHz
In the consultation published on February 19, 2014, Ofcom presented technical analysis of the potential for interference from LTE base stations to Wi-Fi equipment operating in the licence exempt 2.4 GHz band.
Following a request from stakeholders, Ofcom has now published a measurement annex, from the research consultancy MASS.
