This condition is due to a faulty ground command which caused several attenuators to be switched in-line inside the command receiver. It has been determined that about 12 dB of attenuation was accidently switched in. This situation has all the earmarks of the malady which affected DOVE last spring but with one notable exception. In the case of DOVE, it was a stuck transmitter which was caused the command receiver to become desensed and would not allow ground stations to command the stubborn transmitter off. Through the efforts of W5UN and his super EME station, enough EIRP was brought to bear on DOVE to silence its transmitter so ground controllers could start reloading software. Because of the similarity of the problems, it was only logical that the first step controllers decided to do take for AO-21 was to enlist the aid of EME stations. The initial efforts to correct AO-21's problem using EME stations in Europe capable of 10 KW of EIRP have proven so far to be unsuccessful. However, both the AMSAT-DL and AMSAT-U-ORBITA groups feel that they will soon be able to get control of AO-21 using a new commanding scheme they are currently working up. The new scheme will ultimately command the attenuators out of the receeiver circuit. After trying the "sledge-hammer" approach, they have now decided the best way to work the problem now is to use a "ball-ping" hammer instead. Although the latter method may take a little longer, the probability of success appears to be much better. UA3CR would like to thank radio amateurs around the world for providing him with time critical telemetry from the AO-21's CW beacon during the early days of this problem. Please stay tuned to AMSAT News Service (ANS) bulletins for further information concerning the status of AO-21. [ANS thanks G3IOR and W2RS for relaying the information in this bulletin.] /EX SB ALL @ AMSAT $ANS-110.02 WO-18 TAKES BEST PICTURE EVER HR AMSAT NEWS SERVICE BULLETIN 110.02 FROM AMSAT HQ SILVER SPRING, MD APRIL 20, 1991 TO ALL RADIO AMATEURS BT To All: "Land Ho From WO-18" Picture 5 currently transmitting from WO-18 is easily the best quality image of the earth achieved from Webersat to date. It was shot just west of Sumatra. The brightness level is about 180 with lots of contrast. There are both clouds and land features visible. Colorization works nicely and is necessary for best results. The cloud striations in this image appear very much like those visible in outdoor, pre-launch photos taken at WSU with the camera later launched in WO-18. The picture will be left transmitting for several more days.

The AMSAT display will consist of a triple wide booth and will be in the same space as last year: booth numbers 446, 447 and 448. FORUMS Again this year, two AMSAT Forums will be conducted. The first will be on Friday afternoon from 1:30 to 3:00 P.M. The second will be Saturday from 3:00 to 5:00 P.M. They will both be moderated by Jeff Wallach, N5ITU. The agenda of the two forums, as of press time, is as follows: Friday's Forum: Doug Loughmiller, KO5I,"AMSAT, Dedicated to Keeping Amateur Radio in Space." Jim White, WD0E "Microsat Hardware Performance Report" Mike Crisler, N4IFD "Microsat for Beginners", Saturday's Forum: Bill Tynan, W3XO, "SAREX Update" John Champa, K8OCL, "SEDSAT, digital video, Solar Sail, LPO, etc.", Kermit Reister, "Introduction to Webersat.", The talks will range in time from 30 to 60 minutes The booth will have demonstrations of various tracking and telemetry software, along with Models of Phase III and Microsat satellites. The booth is also a Who's Who of AMSAT, so you can visit with many of those people who's teamwork has produced the satellites. It's a time to come up and ask that question which has been puzzling you for the last year. No question is too stupid - or too tough. Much has happened over the past year in the Amateur Radio Satellite program. If you go to Dayton, make a point of stopping by to see how AMSAT is dedicated to KEEPING AMATEUR RADIO IN SPACE. /EX SB ALL @ AMSAT $ANS-110.04 ZRO TESTS RESUME HR AMSAT NEWS SERVICE BULLETIN 110.04 FROM AMSAT HQ SILVER SPRING, MD APRIL 20, 1991 TO ALL RADIO AMATEURS BT Popular Station Receiving Test to Resume in May The ZRO Memorial Technical Achievement Award Program, or just "ZRO Test" has a new schedule for May and early June, 1990 via AMSAT-OSCAR-13. This activity is a test of operating skill and equipment performance. During a typical ZRO run, a control station will send numeric code groups using CW at 10 words-per-minute. At the beginning of the run, uplink power from the control station is set to match the general beacon downlink strength. This is level "zero". The control operator will send and repeat a random five-digit number, then lower the uplink power by 3 dB (half power) and repeat the procedure with a new random number. This will continue to a level 27 dB below the beacon (level "nine"). Participating listeners monitor the downlink signals until they can no longer copy the numbers. Those who can hear the beacon will qualify for the basic award by copying the code group heard at level "zero". The challenge is to improve home-station performance to a point where the lower-level downlink signals can be copied (levels 6 through 9). The following schedule of Mode "B" and "JL" ZRO tests were chosen for convenient operating times and favorable squint angles. The "B" tests can be heard on 145.840 MHz and the "JL" test on 435.945 MHz. Cliff Buttschardt, W6HDO, has changed radio systems and can no longer provide ZRO Test uplink signals for Mode "JL", so Ed Manuel, N5EM, will be taking on the "JL" tests while Andy MacAllister, WA5ZIB, will continue with "B" runs. Cliff's efforts with the ZRO program in 1990 were greatly appreciated. Work has been underway during April to improve transmitter signal calibration at the two stations now providing uplinks. ZRO Test Times and Dates: (in UTC) Saturday May 4, 1991 at 2100 UTC "B" Sunday May 19, 1991 at 0300 UTC "JL" Saturday May 25, 1991 at 1845 UTC "JL" Saturday May 25, 1991 at 2045 UTC "B" Saturday June 1, 1991 at 2230 UTC "JL" Sunday June 2, 1991 at 0030 UTC "B" Note that the dates and days are shown in "UTC", thus the tests on May 19th and June 2nd occur on Saturday nights for those in North America. Any changes will be announced as soon as possible via the AMSAT HF and AO-13 Operations Nets. Recently updated ZRO brochures are available from WA5ZIB, Andy MacAllister, AMSAT V.P. User Operations, 14714 Knightsway Drive, Houston, TX 77083 for an S.A.S.E. with two units of postage. The brochure characterizes test procedures, means for obtaining certificates and gives some historical background about the program. All listener reports with date of test and numbers copied should be sent to WA5ZIB at the address above. A report will be returned verifying the level of accurate reception.

To: info-hams@ucsd.edu I'm building a transverter for 10m->70cm, to be used for the DSY-modems. Transmit and receive seem OK now - haven't checked with an analyser yet - but I have some problems getting the TX/RX antenna switch right. Because it is going to be used for packet, I'm reluctant to use a coax relay. So, I am looking into diode switches. The amateur literature I have hardly mentions this area: transmitters are described, receivers are described, but the integration of these boxes usually isn't covered. So, how to I keep my 25 Watts of RF out of the preamplifier stage? I have looked into commercial designs, but most of them uses striplines on PCB, which are hard to 'borrow'. Has anyone else struggled with this problem? Somebody made a 70cm switch for 25W with kitchentable technology? Tell me how you did it! Thanks in advance! 73, Geert Jan PE1HZG --8<--nip-nip--------------------------------------------------------------- "We trained hard - but it seemed that every time we were beginning to form up into teams, we would be reorganized.

I'm not sure what you mean by "National VECs", but I know that both W5YI and ARRL accept Advanced VEs. Our group uses W5YI, and the form I signed clearly let you check either Advanced or Extra. As for ARRL, if you look in the April QST, you'll see they have an ad for their VE program, and it also has a spot for checking either Advanced or Extra.
