Signals Received From Estonia’s ESTCube-1 CubeSat
Estonia’s first CubeSat ESTCube-1, amateur radio callsign ES5E/S,
was successfully launched from the ESA Spaceport in Kourou in French
Guiana on May 7, 2013 aboard an ESA VEGA rocket.
Built by students at the University of Tartu ESTCube-1 the main
mission of the satellite is to test electric solar wind sail tech-
nology, a novel space propulsion technology that could revolution-
alize transportation within the solar system. It will deploy a 10
meter conductive electrodynamic tether and the force interacting
with the tether will be measured.
Information about the satellite is posted at:
The IARU Amateur Satellite Frequency Coordination Panel have pub-
lished these frequencies for ESTCube-1:
+ 437.250 MHz – CW beacon, callsign ES5E/S
+ 437.505 MHz – 9600 bps AX.25 telemetry, callsign ES5E-11
+ See http://www.estcube.eu/en/radio-details for additional news.
+ A beacon decoder can also be found on a link from this page.
The AMSAT-UK web shows additional photos and a description of the
mission for ESTCube-1 at:
The ESTCube-1 Team has begun posting updates on their facebook page:

After deployment from the VEGA upper stage reception reports of
ESTCube-1 reception reports from amateur radio stations worldwide
+ Ib, OZ1MY received the signal, noting, ”Using the preliminary
TLEs I heard ESTCube-1 beacon at 0908 UTC May 7. The received
frequency is approximately 2 KHz higher than published.”
+ Nader, ST2NH reported, ”EstCube-1 Beacon heard over Africa strong
+ Ken, GW1FKY reported, ”Monday 7th May 2013 – Time here in Wales, UK
1235hrs UTC. Hearing ESTcube-1 very well with just my Elk antenna
and a Kenwood TS-2000.
+ Jean-Pierre, F5YG wrote, ”On orbit number 4, good signal but only
small pieces of text as there is a lot of time between CW frames.
+ Hector, CO6CBF said, ”ESTCube-1 was heard in EL92sd with a great
signal. I was running a FUNcube Dongle with SDR-Radio V2.0 and ELK
antenna with a homebrew preamplifier.
Approximately 12 hours after launch the ESTCube-1 team posted a status
that received telemetry packets indicate the satellite had charged its
The loss of 2300-2400 MHz in a number of counties is resulting in the
investigation of the use of 2400 MHz, see IARU Region 1 paper VIE13_C5_27
New Narrow?Band working frequencies in the 2300 ? 2450 MHz band
As I understand it Japan has always been restricted to 2400-2450 MHz with an
EME allocation at 2424 MHz. The 432 and Above EME newsletter reports that
WiFi is making this unusable and that JARL is now looking at the use of 2400
The newsletter says:
”As discussed in past NLs, our 13 cm allocations, no matter where we are
located, will be difficult to maintain and are subject to attack by
commercial interests. Mike (JH1KRC) writes that the JARL frequency board
would like to renew their band plan (the JARL plan for the legal frequency
allocation), and has requested public opinion on a frequency change.
Specifically it is the JA 13 cm EME band that is being considered for
relocation. It appears that the present JA 2424 EME band may be totally
covered in the near future by WiFi/wireless LAN services worldwide. Thus, JA
EMEers are considering having their EME 13 cm frequency allocation moved to
2400. They would like to hear from you on the interference present at your
location on the present (2424) band and the new (2400) proposed band. Are
these bands clean or jammed? Please send this and any other related
information to Mike email: jh1krc[at]syd.odn.ne.jp by the last week of May,
Through the dedicated work of Stefan Wagener, VE4NSA, AMSAT-NA will debut
its new 1:1 scale cardboard
model of the Fox-1
CubeSat at Hamvention 2013. We will have a complete display at the AMSAT
booth. It is life size, and
based on the latest Fox-1 engineering drawings for highest fidelity in
design and appearance. The
printed in color on heavy stock paper, includes all components and the
instructions are carefully
prepared to allow
for easy assembly requiring scissors, glue etc. Depending on experience,
assembly will take
approximately 10+ hours.
The complete model will be a perfect addition to any satellite operator’s
shack, and a chance to show
visitors what is being done by AMSAT today. We will have finished models at
the AMSAT booth for
display and printed models for sale.
They will be available at the AMSAT booth for a recommended donation of $25.
All proceeds will go to
supporting the Fox Project.
