                         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.

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).

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.

VK2SG RTTY DX NOTES 8 APR 94

NOTES OF INTEREST.

THE ONLY GOOD NOTE FOR THIS WEEK IS A REPORT FROM SYD,  VK2SG.
SYD STATES THAT HE IS IMPROVING AND SEEMS TO BE GETTING BETTER
EACH  DAY.  NICE  TO HEAR FROM YOU SYD AND KEEP  UP  THE  GOOD
HEALTH.

THE  SAD NOTE IS THE DXPEDITION FROM SPRATLY.  PROPAGATION WAS
POOR,  AND  FROM WHAT WE SAW,  WERE CALLINS ONLY ON  NETS  AND
LITTLE  SPLIT OPERATION SSB ON 20 METERS.  NO DIGITAL,  WHAT A
PITY.

FOR  NEXT  WEEK'S BULLETIN,  SEND YOUR BANDPASS AND  NOTES  OF
INTEREST TO JULES, W2JGR AT W2TKU.#SRQ.FL.USA.NA

REMEMBER, DX DON'T SLEEP.
