The voice message, coming from the AO-21 downlink frequency of 145.983 MHz spoke the following words: "I'm completely operational and my ciruits are functioning perfectly." This voice mode is referred to as Mode 8 among the AMSAT-DL and AMSAT-U-ORBITA groups responsible for AO-21's design and assembly. At this time it is not known how often Mode 8 will be in operation on AO-21. Also, engineering checkout is still ongoing and it could be some time before the operational schedule for AO-21 is known. Users should monitor the downlink of 145.983 MHz to see which mode AO-21 is currently operating. As soon as a schedule is available from AMSAT-DL, it will be published immediately in the AMSAT News Service (ANS) bulletins and announced on all AMSAT HF and VHF nets. /EX SB ALL @ AMSAT $ANS-061.02 BRIEF MICROSAT UPDATE HR AMSAT NEWS SERVICE BULLETIN 061.02 FROM AMSAT HQ SILVER SPRING, MD MARCH 2, 1991 TO ALL RADIO AMATEURS BT Quick Status Report on Microsats LO-19 crashed during a pass over the U.S. early on Saturday, March 2, 1991 UTC. At press time, the reason for the crash was being ascertained from satellite memory dumps. A reload, coordinated between Microsat software developers and the LUSAT command group in Argentina, was pending. WO-18 was recovered from a crash last weekend (February 22) and reloaded. Picture taking activities were expected to resume nearly immediately at press time. DO-17. Now that a reasonable amount of experience has been obtained from the other Microsat missions (AO-16, WO-18 and LO-19) and they are largely under the control of their operational teams, software development priority has been shifted to DOVE. Due to the special circumstances of DOVE controlling, this conservative approach is considered to be the only prudent way to develop this precious and powerful resource. The Microsat hardware and software development teams are to be congratulated on this, the final chapter in a long development process of four complete and independent satellite missions! (Five complete satellite missions counting the parallel software development undertaken on UO-14.) As progress is made with DOVE, and in coordination with BRAMSAT, packet bulletins (such as ANS) are expected to appear first followed by voice experiments. AO-16 performed nominally and logged nearly 1000 messages in the space of one month. Some of these messages were of considerable length, several tens of kilobytes. Gateway service to AKNET to Alaska had handled several dozen messages which would previously have taken considerably longer and riskier HF routes. LO-19 was being used for this task as well. Watch AMSAT publications for information about this Gateway and ideas on how to set up others. The Pacsat team is particularly interested in providing Gateway service to remote areas not now well served by other packet systems. AO-16 crashed about 12 hours after LO-19 on 2 March 91 UTC. The AMSAT-NA Operations command team and pacsat software developers were reviewing the situation at press time. Depending on the cause of the problem, the file server is expected to be back on within a week. Please do not transmit to the satellite when the digi is off. This will only slow uploading of new software. /EX SB ALL @ AMSAT $ANS-061.03 EXPERIMENTERS DAY SCHEDULE HR AMSAT NEWS SERVICE BULLETIN 061.03 FROM AMSAT HQ SILVER SPRING, MD MARCH 2, 1991 TO ALL RADIO AMATEURS BT PACSAT Experimenter's Day Operations Schedule Set The schedule for future PACSAT Experimenter's Day operations is: DATE START TIME END TIME 06 March 0454 UTC - 06 March 0428 UTC - 07 March 13 March 2215 UTC - 12 March 2145 UTC - 13 March 20 March 0500 UTC - 20 March 0430 UTC - 21 March 27 March 0320 UTC - 27 March 0255 UTC - 28 March 03 April 0505 UTC - 03 April 0615 UTC - 04 April While operation of the S-Band and raised cosine PSK transmitters is scheduled to be conducted weekly, users are cautioned that these operations may be shortened or canceled to allow uploading of improved spacecraft software.

Currently, OSCAR-10 is obviously no longer receiving sufficient solar panel illumination to support even the beacon much less alone the transponder. PLEASE DO NOT attempt to use OSCAR-10 until further notice. This period of dormancy is expected to last for approximately 3 months. As soon as OSCAR-10 can support Mode-B transponder operations it will once again be released for general use.

Also, what are the most useful/popular/common bands on which hams communicate above 30Mhz that are available to no-code techs and what are they usually used for? Cost is not much of an object to me. I'd rather get a fairly good radio to start, than to have to upgrade soon. Thanks, -- David J.

I am restricted by CC&R's to no external antenna, but have ample room in the attic. I was thinking about a Butternut H5 on a small rotator, any comments? also, I am mainly interested in 10m and SWL, no CW, but would like to keep my options open. I have heard alot about the Icom 735 and the kenwood 440, but not much about Yaesu... are these considered junk? like the 747?? any info would be greatly appreciated!

How is the PRO2006 different than the PRO2004/5? Here are some modifications for the PRO2004 and PRO2005. Maybe this will help you. o Restoring the missing 800 Mhz frequencies. PRO-2004: Clip or remove diode D-513 PRO-2005: Clip of remove diode D-502 o Speeding up scan rate from 8/16 to 10/20 channels per second. PRO-2004: Add a diode where D-514 would go. (use IN914 or IN4148). PRO-2005: Add a diode where D-501 would go. (use IN914 or IN4148). Note that the PC board may not be labeled D-514. It would go between D-513 and D-515. Same idea goes for the PRO-2005. o Speeding up scan rate ever more by crystal replacement method. First perform the above diode speedup modification. Then replace crystal CX-501 with a 9 or 10 MHz crystal. Note that on some scanners a 10 MHz crystal may be too fast. Some experiementation may be necessary. I got mine to work on the first 10 Mhz crystal I tried. Also if the new crystal has a metal case, wrap plastic tape around it so it will not make contact with surrounding components. o 400 channels for the PRO-2004. Add a diode where D-510 would go. (use IN914 or IN4148) Poof! You now have 400 channels just like a PRO-2005. o For more modifications on the PRO-2004/5 including 6400 channel mod, purchase (or borrow) the book "Scanner Modification Handbood" by Bill Cheek. Available for $20 from CRB Research Books, Inc., PO Box 56, Commack, NY, 11725. o To answer your question about D-504. If D-504 were removed, it will delete 66-88 MHz converage.

UNFORTUNATELY FOR HF USERS, THE RETURN APPEARANCE OF THIS GROUP DID NOT BRING BACK THE DRAMATIC CONDITIONS OF A MONTH AGO. ON JANUARY 30 THE FLUX PEAKED AT 367, AND 25 DAYS LATER IT REACHED 311. NOT ONLY WAS THE PEAK OF FEBRUARY 24 DRAMATICALLY LOWER THAN IN THE PREVIOUS SOLAR ROTATION, TOWARD THE END OF THIS WEEK THERE HAS BEEN A SLIGHT RISE IN THE K AND A INDICES. AN INCREASE IN THESE INDICES MEANS POORER CONDITIONS, ESPECIALLY ON HIGH LATITUDE PATHS. LOWER LATITUDES ARE LESS AFFECTED, AND TRANSEQUATORIAL CONDITIONS MAY EVEN BE ENHANCED IF THE K INDEX RISES TO 4 OR HIGHER, ESPECIALLY ON 10 AND 6 METERS. FOR THE ARRL DX CONTEST WEEKEND, LOOK FOR A FALLING SOLAR FLUX, POSSIBLY BELOW 200, WITH A INDICES BETWEEN 12 AND 15. CONTESTERS CAN STILL BE GRATEFUL FOR GOOD CONDITIONS EVEN THOUGH THEY ARE NOT QUITE WHAT WE EXPERIENCED A MONTH AGO. CONDITIONS OVER THE FORECAST WEEK SHOULD BE GOOD, WITH LOW TO MODERATE SOLAR ACTIVITY AND VERY LITTLE PROBABILITY OF MAJOR FLARES. LATE IN THE WEEK THE FLUX MAY DROP TO AROUND 160 OR 170, ABOUT 200 POINTS LOWER THAN IT WAS ONLY A MONTH AGO. AMERICAN SUNSPOT NUMBERS FOR FEBRUARY 21 THROUGH 27 WERE 197, 194, 175, 170, 143, 147 AND 126 RESPECTIVELY, WITH A MEAN FIGURE OF 164.6. NNNN -- Gary W.
