OSCAR-11, also known as UOSAT-2, was designed and built by a team of engineers at the University of Surrey in Guildford, Surrey, UK as the successor to OSCAR-9 / UOSAT-1 (see Hobby Electronics August 1981).
It was launched from the Western Test Range at Vandenberg Air Base, in Lompoc, California along with LANDSAT-5 on a Delta 3920 rocket on March 1, 1984.
OSCAR-11 was the most rapidly designed OSCAR, going from inception to launch in only five months. It was also the first amateur satellite to carry a digital communications package into Earth orbit, and the first to be controlled by a CPU running software written in the high-level programming language “Forth”.
OSCAR-11 carries beacons in three amateur radio bands.
The 145.826 MHz beacon transmits FM Audio Frequency Shift Keying (AFSK) 1200 bps ASCII data. It the early years it also transmitted a voice message from the digitalker experiment.
The 435.025 MHz beacon transmitted either 1200 bps FM AFSK or 4800 bps PSK data. This beacon was used to downlink information from the Digital Store and Readout (DSR) Experiment, which includes CCD Earth image data, results from the Particle Wave Experiment, and engineering data from the RCA COSMAC 1802 CPU.
The 2401.5 MHz beacon transmitted FM and PSK signals. Antenna polarization for all three beacon transmitters is left-hand circular (LHCP). Only the 145.826 MHz beacon is now operational.

They will be deployed into a 325×315 km 51.5 degree inclination orbit. You should be able to watch the launch live on NASA TV at http://www.nasa.gov/multimedia/nasatv
A Sprite is a tiny, 3.5 by 3.5 cm, single-board spacecraft that was developed by Zac Manchester KD2BHC. It has a microcontroller, radio, and solar cells and is capable of carrying single-chip sensors, such as thermometers, magnetometers, gyroscopes, and accelerometers.
The 200 Sprites are carried in a 3U CubeSat called KickSat. They are stacked atop a spring-loaded pusher and secured by a nichrome burn wire system.
On reaching orbit KickSat will perform a de-tumble maneuver and establish communication with Cornell University’s ground station. After check-out, the spacecraft will be put in a sun-pointing attitude and spun up to maintain that attitude.
A command signal from the ground station will then trigger the deployment and the Sprites will be released as free-flying spacecraft. After deployment, telemetry and sensor measurements from the individual Sprites will be received through Cornell’s ground station in Ithaca, NY, as well as several other amateur ground stations around the world.
Due to the low orbit Sprites will have a short lifetime before they re-enter the atmosphere and burn up. In the best-case scenario the orbital lifetime could be six weeks but realistically it may be considerably shorter depending on atmospheric conditions.
All Sprites operate on a single frequency of 437.240 MHz and use Code Division Multiple Access (CDMA). The transmitter runs 10 mW output of Minimum Shift Keying (MSK) modulated binary data with each data bit modulated as a 511 bit Pseudo-Random Number (PRN) sequence. The ITU emission designator is 50K0G1D.
The KickSat CubeSat has downlinks on 437.505 MHz and 2401-2436.2 MHz.

The release follows the release of a memorandum issued in 2010 by President Obama titled Unleashing the Wireless Broadband Revolution. In it the Department of Defense is required to make available 500 MHz of spectrum for commercial use by 2020.
It should be noted that a good number of amateur UHF and Microwave spectrum allocations are shared with the Department of Defense but at this point in time its not known what impact, if any, the release of the required 500 MHz could have on future ham radio operations.

An Ohio town is appealing the States PRB-1 like law into the court system. This after it lost an appeal by a ham who was given the right to put up an antenna that the municipality had denied. We have the latest from Amateur Radio Newsline’s Stephan Kinford, N8WB:
On February 4th the Village of Swanton Ohio filed a notice of appeal of its intention to challenge the decision of the Fulton County Common Pleas Court in the case of Gary Wodtke versus the Village of Swanton.
The legal issue began when the Village denied Gary Woodtke’s tower application and Wodtke, who holds the call WW8N, appealed that decision to the Fulton County Common Pleas Court. The Court ruled in favor of Wodtke telling the Village that it must approve a variance to WW8N’s antenna support structure. Instead the Village is now appealing that order into the Court of Appeals for the Sixth District.
In its docketing statement the Village of Swanton asserts four potential issues including one that questions whether Revised Code Section enacted by H.B. 158, which is Ohio’s version of the Federal PRB-1 statute is constitutional. It also questions whether H.B. 158 was constitutionally applied in this case.
Ohio law grants a right of appeal from final decisions of a Common Pleas Court. Appellate decisions are heard by a three judge panel that is usually designated near the time for oral argument. Decisions normally take a number of months after oral arguments are made.
Appellate decisions are generally final, unless further review is granted by the Ohio Supreme Court. While such a Court of Appeals decision represents the law only in that appellate district, it has the ability to be used as a significant precedent in other Ohio courts. It also can be cited in cases in other states that have passed similar state versions of the FCC regulations that are outlined in the text of PRB-1.
Late word is that the ARRL has announced its intention to file a Friend of the Court brief on behalf of Woodtke. This is likely because of the long term potential a finding against WW8N might hold by impacting on any ham living anywhere in the United States.
WW8N is represented by Toledo attorney Carey Cooper and by Fred Hopengarten, K1VR. Hopengarten is considered a national authority on zoning law and amateur radio antenna issues.

It's a long complicated story, but this has been in the courts since 2008. And Gary still doesn't have his tower.
And this is NOT a CC&R or HOA issue! It's the city council who is stopping him at every turn. More details at http://forums.qrz.com/showthread.php...ll-US-amateurs. Ignore all the thread hijackers and the incorrect assertions that "he shouldn't have moved into an HOA" because that is NOT the case here!

FROM THE STATE GOVERNMENT LIAISON..
Village of Swanton Antenna Decision Appealed..
On February 4 the Village of Swanton filed a notice of appeal, appealing the decision of the Fulton County Common Pleas Court in the case of Wodtke v. Village of Swanton. The case is the first court case that we are aware of involving application of Ohio’s new antenna legislation, H.B. 158 (129th General Assembly). The Trial Court ordered the approval of an application to the village by Gary Wodtke, WW8N, for approval of an antenna variance. The Village denied the application and Mr. Wodtke appealed that decision to the Fulton County Common Pleas Court. The Court ruled in Mr. Wodtke’s favor and the Village is now appealing that order. In the docketing statement filed with the Court of Appeals the Village asserts four potential issues to be argued in the appeal, including whether Revised Code Section 5502.031, enacted by H.B. 158, is constitutional and whether it was constitutionally applied in this case.
Ohio law grants a right of appeal from final decisions of a common pleas court. The decision here is appealed to the Sixth District Court of Appeals, headquartered in Toledo. The appellate process involves first, filing the record of proceedings in the common pleas court, then briefs of each of the parties and, finally, a brief oral argument to the court. Appellate decisions are heard by a three judge panel that is usually designated near the time for oral argument. Decisions normally take a number of months after oral argument. Appellate decisions are generally final, unless further review is granted by the Ohio Supreme Court. While a court of appeals decision represents the law only in that appellate district, it carries significant precedential value in other Ohio courts and may also be cited in similar cases in other states.
Mr. Wodtke is represented by Toledo attorney Carey Cooper and by Fred Hopengarten, K1VR a noted authority on zoning and amateur radio antenna issues. ARRL leadership at the national level is also aware of the appeal. Scott Yonally, Ohio Section Manager and Jim Weaver, Great Lakes Division Director have enlisted support from the ARRL. In my discussion with League General Counsel, Chris Imlay, W3KD, it appears that the leadership of the League views this appeal as being one of precedential significance, not only for Ohio amateurs, but also for amateurs in other states that have passed state versions of FCC regulation PRB-1.
Discussions are ongoing regarding various ways to help bring this appeal to a successful conclusion. We will keep you informed as further developments occur.

The Communications Act, first written in 1934, created the Federal Communications Commission and outlined rules governing communications as it stood at that time. Over the years it has been amended on many occasions to try to keep up with emerging technologies. The Act was last updated in 1996, when the Internet was still in its infancy.
The House Energy and Commerce Committee has already begun to look into ways to bring the Communications Act into line with the needs of the 21st Century, but Pryor who is chairman of the Senate Commerce Subcommittee on Communications said the overall Senate Commerce Committee probably will not be following suit.
Critics of the current Communications Act have said that it creates what they call silos for different type of communications. That they say has posed a problem for new technologies such as Voice over Internet Proytocol phone calls that are transmitted over broadband and other Internet lines.
The House of Representatives effort to rewrite the law is expected to take multiple years, and has only just gotten started. This past January an Energy and Commerce Subcommittee held its first hearing on the issue with five former FCC chairmen in attendance.

HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
