CHINA HAM NEWS APRIL 16, 1994 EDITED BY RICK NIU, BZ1QL CHINA HAM NEWS IS ORIGINATED AT BY1QH, OPERATED BY THE TSINGHUA UNIVERSITY AMATEUR RADIO CLUB IN BEIJING, CHINA. IT IS RELEASED FIRST AND THIRD WEEKENDS EVERY MONTH, AND IS AVAILABLE FOR UNLIMITED DISTRIBUTION. WE WHOLEHEARTEDLY CONGRATULATE OUR GOOD, OLD FRIEND DIETER, DJ7BU, ON OBTAINING HIS AMATEUR RADIO OPERATOR'S CERT- IFICATE FOR VISITORS. A SIEMENS DEPUTY DEPARTMENT MANAGER, DIETER HAS BEEN WORKING, BOTH IN THE BUSINESS AND HAM RADIO AREAS, IN SHANGHAI, GUANGZHOU AND BEIJING FOR OVER FIVE YEARS, AND IS PRETTY WELL KNOWN IN THE CHINESE AMATEUR RADIO COMMUNITY. SINCE MARCH 25, 1994, DJ7BU/BY1QH HAS BEEN OFFICIALLY VALIDATED AND IS OWNED BY A GERMAN RADIO AMATEUR OPERATING FROM THE PEOPLE'S REPUBLIC OF CHINA. 1ST DIGITAL BA... WHEN A BY1QH MEMBER SPOT BA1GYS ON HF PACKET, EVERYBODY SAID THERE MUST BE SOMETHING WRONG WITH THE SYSTEM. BUT THE NEXT DAY WHEN RICK TALKED WITH MR. GUO YUNSHENG (GYS, THAT IS), HE SAID HE WAS HOPING TO LEARN MORE ABOUT PACTOR1 EQUIPPED WITH TWO STANDARD TUS (A GERMAN HC AND A YX-9001) AND A 386 COMPUTER PLUS A KENWOOD 440, BA1GYS IS TRYING TO BRING THE 20-ODD BA GROUP INTO THE MAGIC WORLD OF DIGITAL COMMUNICATIONS. RIGHT NOW GUO'S PROBLEM SEEMS TO LIE IN THE LACK OF RELATED REFERENCES, BOOKS, HARDWARE AND SOFTWARE, PREFERABLY FOR PACKET AND PACTOR. IF YOU ARE INTERESTED IN HELPING THE BA GET UP AND RUNNING, AND YOU HAPPEN TO BE ABLE TO DO GUO A FAVOR, PLEASE DIRECT WHATEVER YOU MAY SEND HIM TO: MR. GUO YUNSHENG, BA1GYS C/O RICK NIU, BZ1QL, ROOM 316 BUILDING 25, TSINGHUA UNIVERSITY, BEIJING 100084, CHINA. HAM RADIO ON BEIJING TV... A 25-MINUTE ENGLISH LANGUAGE TELE- VISION PROGRAM ABOUT AMATEUR RADIO AND THE TUARC WAS AIRED ON BEIJING TELEVISION (BTV) FEBRUARY 20. THIS MAY HAVE BEEN THE VERY FIRST TIME IN CHINA THAT OUR HOBBY IS INTRODUCED TO THE GENERAL PUBLIC VIA A NOTED TV STATION. FOUR OF THE CLUB MEMBERS - NICK, GRAY, JOHN AND SEAN - DID A SUPER JOB IN THE SHOW WHILE RICK WAS BEHIND THE SCENE AS AN ASSISTANT DIRECTOR. THANKS TO SAM N3NFK FOR A VIDEOTAPE OF REFERENCE. BT2000BJ QSLS... AT LAST, ALL THE STACKED BT2000BJ QSL CARDS WERE SENT OUT IN THE FIRST WEEK OF APRIL FROM TUARC. AGAIN WE DEEPLY APOLOGIZE FOR SUCH AN 'UNBEARABLE' DELAY. BY THE WAY, THE BY1QH CALLBOOK QSL ROUTE STILL WORKS PERFECT: P.O. BOX 2654, BEIJING, CHINA. (These were some excerpts from the Chinese amateur scene. The item was too long to run in its entirety. --------------------------------------- G-TOR, the new faster HF digital mode ... part 1 by Phil Anderson W0XI and others, from an article in the RTTY Digital Journal March 1994 On New Years Day, W0XI and WK5M transmitted a 9,718 byte file from Kansas to WA4EGT in California on 20-meters in 5 minutes, 20 seconds. The mode was G-TOR. Immediately thereafter, the file was transmitted again, this time using Pactor. It took 20 minutes, 15 seconds. Throughout the month of January these tests were repeated with over one-million bytes transferred error-free. The average character/second rate for G-TOR was 23.7 and for Pactor 8.64. G-TOR, short for Golay-TOR, is an innovation of Kamtronics Co., Inc. It is a new HF digital communications mode for the amateur service. The error correction coding outlined in MIL- STD-188-141A forms the basis for G-TOR. In order to keep costs low yet take advantage of concepts prescribed in the standards G-TOR makes use of exisiting multi-mode TNC hardware but establishes a completely new hybrid-ARQ system in firmware. The benefits of these innovations are exceptional: - dramatically increased throughput - apparent reduction in the effects of interference an multi-path - low cost. The key features of G-TOR are atypical: - extended Golay forward error correction coding - full-frame data interleaving - on-demand Huffman data compression with run-length encoding - link-quality based baud rate: 300, 200, or 100 - 2.4 second hybrid ARQ cycle - fuzzy acknowledgements - reduced overhead within data frames - standard FSK tone pairs (mark and space). more next week ----------------------------------------- IPS weekly report ----------------- 15 April - 21 April 1994 Issue No 16 Date of issue: 22 April 1994 INDICES: Date 15 16 17 18 19 20 21 10cm 080 082 082 084 085 086 087 A 15 17 60 20 15 08 (08 estimated) T 24 38 67 20 40 39 39 SUMMARY OF ACTIVITY Solar activity was very low 15th - 20th, and low on April. The geomagnetic field at Learmonth (WA) was unsettled 15th- 16th except for a minor storm period on 16th. The field was at major storm levels on 17th, reducing to quiet to unsettled by end of the 19th, at which levels it remained until the end of the period. Ionospheric F2 critical frequencies at Sydney on 15th and 18th were near normal or depressed by up to 15 per cent, on 17th, frequencies were enhanced by up to 30 per cent. Over the remainder of the period frequencies were near predicted monthly values. FORECAST FOR THE NEXT WEEK (22 - 28 April) SOLAR: Low GEOMAGNETIC: Quiet to unsettled, possibility of active levels on 28th. Further geomagnetic activity expected after 28th. IONOSPHERIC Near normal.
