Status of ISS Ham Radio Operations
ISS Amateur Radio Project Engineer Kenneth Ransom, N5VHO reports the
ARISS digipeater has changed frequency from 145.825 MHz (up/down) to
437.550 MHz (up/down). The same digi alias ARISS is still used.
This change was started with the docking of the ESA Automated Trans-
fer Vehicle (ATV). The ATV is an expendable, unmanned resupply space-
craft delivering propellant, water, air, payloads and experimental
supplies to the International Space Station (ISS).
Packet operations were moved to the Columbus Module UHF radio when
the Kenwood D700 radio was recently powered off due to needing an
additional air purifier to support the ATV. Normally the air puri-
fier is located in the ATV but recent power support issues related
to the ATV and ISS necessitated the system be relocated to the Ser-
vice Module. The purifier is now using the power outlet that the
Kenwood radio normally uses. The Russian team has agreed to briefly
power the purifier off for the scheduled ARISS school events but then
will re-activate the purifier right afterwards. This appears to be a
long term impact as ATV is currently scheduled to depart from ISS in
September.

SA AMSAT Update Reports That SumbandilaSat Recovery Work Continues
SA AMSAT posted a report on their web (http://www.amsatsa.org.za/)
there is still a recovery opportunity for SumbandilaSat.
The team at SunSpace are still incrementally reading back the pro-
gram code from the nine power modules in an effort to determine the
extent of the corruption. With SumbandilaSat going through eclipses,
the satellite is not as much available as the team would like. Sum-
bandilaSat's batteries failed which means that the satellite is only
active when the solar panels are illuminated.
"We need the information to confirm that the changes we made to stop
repeated corruption were effective." Johann Lochner ZR6CBC who spends
considerable of his free time on recovery of SumbandilaSat said. "It
is our aim to ultimately reprogram one of the power modules to auto-
matically switch the amateur radio transponder on and off."
Because of the shorter illumination of the solar panels in the South-
ern hemisphere and most likely poor orientation of the satellite with
respect to the sun, progress is much slower than originally antici-
pated. "Where we had three passes to work with in January we current-
ly have one", Johann said.
In early June 2011 for an unknown reason (but probably related to a
major radiation event on 7 June) the primary controller on the power
distribution unit (PDU) powering the On-Board Computer (OBC) stopped
responding to commands from the ground station.
It later appeared that the battery had failed and nothing was heard
from the satellite for some time. The ground stations at SANSA Space
operations at Hartbeeshoek and the Electronic Systems Laboratory at
Stellenbosch University are receiving telemetry when the satellite's
solar panels are illuminated by the sun.
Johann said with SumbandilaSat responding when it is in full sunlight
the team is confident that some operations will be restored even to
the point where it may be possible to do some imaging and have the
amateur radio transponder back in operation.

Amateur Radio Reports Requested for AubieSat-1
John Klingelhoeffer, WB4LNM, AubieSat-1 Technical Mentor at Auburn
University is requesting telemetry reception reports from amateur
satellite operators after a new operating mode is commanded aboard
the satellite.
AubieSat-1 was launched from Vandenberg AFB, California in October,
2011. The cubesat is an undergraduate built satellite developed by
Auburn University. Over the weekend of June 9-11 the AubieSat-1
controllers changed the transmission mode of the satellite to in-
crease the quantity of telemetry. The increased telemetry rate will
provide data to indicate how well solar cell protection is working.
It should also provide additional onboard housekeeping information.
AubieSat-1 transmits with a power of about 800 milliwatts on a freq-
uency of 437.475 MHz. The beacon signal, along with telemetry, is
sent using A1A continuous wave Morse code at 20 words per minute.
Additional telemetry from the onboard science experiment will use
CW transmissions up to 60 WPM.
Please post your reception reports on the AMSAT-BB.
An example of receiving the AubieSat-1 downlink can be found on the
DK3WN SatBlog: http://www.dk3wn.info/p/?p=23582

ARRL 9 cm Band Plan Updated
Outside of ITU Region 1, the Amateur Satellite Service has a 9cm band
allocation of 3.400 GHz - 3.410 GHz on a non-interfering basis. No
current satellites are active on this frequency range at present.
The new band plan reserves allocations for EME and amateur satellite
operation.
The detailed graphic of the 9 cm band plan and accompanying article
is posted on the ARRL web at:
http://www.arrl.org/news/arrl-board-of-directors-approves-9-cm-band-plan
In ARRL Bulletin 14 ARLB014, released on June 5 the report reads:
The ARRL Board of Directors has unanimously voted to approve the 9
cm band plan, as presented by the ARRL UHF/Microwave Band Plan
Committee. Earlier this year, the committee asked radio amateurs for
comments on a proposed 9 cm band plan, explaining that the purpose
of these band plans is to share information about how the amateur
bands are being used and to suggest compatible frequency ranges for
various types of application. The committee also recognized that
local conditions or needs may necessitate deviations from a band
plan, and that regional frequency coordinating bodies may recommend
alternatives for use in their respective regions.
The new 9 cm band plan includes the following notations:
* This band plan includes all other emission modes authorized in the
9 cm amateur band whose necessary bandwidth does not exceed the
suggested bandwidths listed.
* Weak Signal Terrestrial legacy users are encouraged to move to
3400.3-3401.0 MHz, as time and resources permit.
* Broadband segments may be used for any combination of high-speed
data (e.g. 802.11 protocols), Amateur Television and other
high-bandwidth activities. Division into channels and/or separation
of uses within these segments may be done regionally, based on need
and usage.
* Per ITU RR 5.149 from WRC-07, these band segments are also used
for Radio Astronomy. Amateur use of these frequencies should be
first coordinated with the National Science Foundation.
