SB SAT @ AMSAT $ANS-274 02 PCSAT-1 Recovery

AMSAT News Service Bulletin 274 02 From AMSAT HQ SILVER SPRING, MD October 1, 2006 To All RADIO AMATEURS BID: $ANS-274 02

PCSAT-1 has been recovered as it entered better sun angles

PCSAT-1 should remain NORMAL OPS for the next few weeks until it experiences an overload and resets Then it will be lost until December All users are asked to please adhere to these fundamental principles:

1) No connections to or through PCSAT-1 2) UI digipeating and APRS packets only about a 1 minute rate 3) Watch pcsat aprs org for live activity 4) Use the path of VIA PCSAT-1 or VIA ARISS 5) Minimize all packets after dark!

Enjoy PCSAT-1 and APRS! Make contacts, QSO, enjoy!

Just remember that ACKS are pretty useless and only add QRM to the channel So do not expect ACKS via the satellite If you see your outgoing packet digipeated by PCSAT-1 a few times then you should ASSUME that the other person got it and delete it yourself By the same token, if someone sends you a message, then ANSWER him in kind, so that he knows you got it

SB SAT @ AMSAT $ANS-274 03 PCSAT-1 Special Ops

AMSAT News Service Bulletin 274 03 From AMSAT HQ SILVER SPRING, MD October 1, 2006 To All RADIO AMATEURS BID: $ANS-274 03

Bob Bruinga, WB4APR, with the US Naval Academy Satellite Lab provided the following update on PCSAT-1 special operations

We now welcome routine trackers and unattended beacons so that we can build up statistics on channel loading and the channel capacity of PCSAT-1 and it's follow-on spacecraft We do want everyone to include basic info in their packet though Please include PWR,Antenna Gain, and RATE Such as "5W,3dbi,5min" so that the statistics will show us what works

PCSAT-1 works like any APRS digipeater so the only thing you have to do, to work the satellite is to change your APRS (or packet station) channel to 145 825 instead of its normal frequency When you get to work, QSY to 145 825 during the day, and when you get home Its nice to look at your mobile radio and see who else you captured after work or overnight

For unattended, set your beacon rate to once ever 5 minutes If attended and monitoring the channel, you can use 2 minutes You can see if you got in on http://pcsat aprs org Watching the capacity of PCSAT-1 to carry these data will be usefull for gauging the success of our next satellite, ParkinsonSAT See http://www ew usna edu/~bruninga/buoy html

PCSAT-1 responds to most common digipeating callsigns (below) so that no one should have to change anything when going between terrestrial or ISS operation to PCSAT-1, other than their frequency

PCSAT-1
RELAY
WIDE
WIDEn-N
ARISS
TRACEn-N

We saw 22 people yesterday on the East Coast and the web page above, is showing about 70 in the last 2 days PCSAT-1 should be able to handle 100 or so per footprint PER PASS! So lets get the number of users up for the next 2 weeks of useful PCSAT-1 life

See web page PCSAT APRS ORG or Google for PCSAT

SB SAT @ AMSAT $ANS-274 04 AMSAT Represented at NBC4 Connected Expo

AMSAT News Service Bulletin 274 04 From AMSAT HQ SILVER SPRING, MD October 1, 2006 To All RADIO AMATEURS BID: $ANS-274 04

Amateur Radio and Amsat were represented at the 6th annual "NBC4 Connected Expo" in downtown Washington DC on September 16 and 17 This event is sponsored by local television station WRC channel 4 in Washington and hosted by their on-air technology reporter I J Hudson, K9ICF

25,000 people attended the event over the two days that it was open The ham radio exhibit was located just around the corner from a robotics demonstration that drew a large number of technically inclined young people

The general public really has little idea what ham radio is all about and often confuses hams with CB operators or thinks of hams as old men who tap out messages in morse code on vacuum tube radios Many believe that ham radio is no longer useful or relevant in the age of cellular telephones and the internet Comments that were heard during the weekend included "Look at the fancy cell phone!", "My father was a ham when I was young" and "I didn't know you still did that" Many visitors were surprised to learn that ham radio is still alive and well and fully up to date with modern technology A few lapsed hams also thought about getting back into amateur radio after stopping at the exhibit

The fact that hams build satellites and talk to astronauts in space was a major part of the exhibit These are two things that citizens band operators and cellular telephone users don't do A recent ARISS contact between astronauts and school children played almost continously during the expo to draw people into the exhibit

The exhibit also stressed the technical opportunities that are available in ham radio, that hams can design, build and modify their own transmitters and other equipment and that amateur radio provides practical electronics experience and is a great way to get a head start in a science or engineering career Displays also showed off the public service abilities of hams and stressed that ham radio still works after all other communication systems have failed

Visitors who were interested in learning more about amateur radio were directed to one of the many local radio clubs in the Washington area that offer licensing classes and exam sessions Although the outcome of the exhibit cannot be accurately measured, we do know that last year's exhibit did produce one new ham that we know of, and possibly more that we don't know about

SB SAT @ AMSAT $ANS-274 05 OSCAR 11 Report - 28 September 2006

AMSAT News Service Bulletin 274 05 From AMSAT HQ SILVER SPRING, MD October 1, 2006 To All RADIO AMATEURS BID: $ANS-274 05

                OSCAR-11 REPORT

               28 September 2006

NOTHING HEARD FROM OSCAR-11 DURING SEPTEMBER REPORTS REQUESTED! Please post reports to AMSAT-BB or e-mail to xxxxx@amsat org (replace xxxxx by g3cwv)

During the period 14 August 2006 to 28 September, the satellite was heard from 16 to 26 August The beacon was expected to switch ON ten days or 20 later, ie around 05 or 15 September However, it has not been heard since 26 August

During the last ON period, the real time clock showed various errors The date on 16 August was 51 July By 26 August it had incremented to 60 July The hours were also showing an erratic behaviour Over short periods of time, ie during a pass, the minutes and seconds appeared to be incrementing correctly

I am indebted to Jeff KB2M, Peter ZL3TC and Dave G1OCN, for their reports and for monitoring the satellite, especially during the last two weeks while I have been away on holiday Many thanks

The status of the satellite, when last heard, was that all the analogue telemetry channels, 0 to 59 are zero, ie they have failed The status channels 60 to 67 were still working The spacecraft computer and active attitude control system have switched OFF, ie the satellite' attitude is controlled only by the passive gravity boom gradient, and the satellite is free to spin at any speed When telemetry was last received it showed that one of the solar arrays had failed, and there was a large unexplained current drain on the main 14 volt bus After 22 years in orbit the battery has undergone around 100,000 partial charge/discharge cycles, and observations suggest that it cannot power the satellite during eclipses, or sometimes during periods of poor solar attitude

The watchdog timer now operates on a 20 day cycle During the three months before May (when the eclipses started), the ON/OFF times were very consistent, and the average of many observations show this to be 20 7 days, ie 10 3 days ON followed by 10 4 days OFF However, poor solar attitude may result may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle When this occurs, the beacon is OFF for 20 7 days

The Beacon frequencies are -

VHF 145 826 MHz AFSK FM ASCII Telemetry

UHF 435 025 MHz OFF

S-band 2401 5 MHz OFF

Listeners to OSCAR-11 may be interested in visiting my website If you need to know what OSCAR-11 should sound like, there is a short audio clip for you to hear The website contains an archive of news & telemetry data It also contains details about using a soundcard or hardware demodulators for data capture There is software for capturing data, and decoding ASCII telemetry The URL is www users zetnet co uk/clivew/
