SUBJ: INTRODUCTION OF BETA VERSION OF WIMNOR RMS TO MARS
A. AAAA9AC TN E-MAIL SENT SUN, 13 DEC 2009 16:20:00 NOTAL
THE FOLLOWING IS A SHORTENED, EDITED VERSION OF REF A:
1. WINMOR BETA TEST STATION, AAA9AC-5 HAS BEGUN BETA OPERATION ON
FREQ NCM 24 X 7 FROM NASHVILLE, TN. THIS IS ONLY A BETA
TEST PROGRAM, SO IT MAY BE OFF AND ON AGAIN, DEPENDING ON HOW THE
ACTUAL TESTING GOES.
2. TO OBTAIN THE PROPER WINMOR RMS CLIENT PROGRAM, PLEASE JOIN THE
WINMOR YAHOO REFLECTOR AND LOOK IN THE FILES SECTION FOR A COMPLETE
INSTALL. MY STRONG SUGGESTION IS TO USE THE SIGNALINK USB EXTERNAL
SOUND-CARD WITH VOX, AND DELAY AT A MINIMUM WITH A DRIVE LEVEL UP
PAST '90.' IN ADDITION, IF YOU FIND LACK OF AUDIO, CHANGE BOTH TX
AND RX JUMPERS IN THE SIGNALINK PER THEIR INSTRUCTION. THE WINMOR
YAHOO REFLECTOR HAS A LARGE CONTINGENCY OF TESTERS USING THE SYSTEM
CURRENTLY, AND THOSE ON THIS REFLECTOR CAN ASSIST YOU WITH ANY
DIFFICULTIES YOU MAY EXPERIENCE WITH 'RMS EXPRESS,' THE CLIENT
PROGRAM FOR WINMOR OPERATION.
3. WINMOR IS AN ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING (OFDM),
AUTOMATIC REQUEST TO SEND (ARQ) PROTOCOL, SIMILAR TO PACTOR 3, BUT
WITH LESS SPEED, AND ROBUSTNESS. LIKE ALL WINLINK 2000 DATA
TRANSFERS, IT USES THE SAME B2F BINARY COMPRESSED FORMAT AS PACTOR,
PACKET AND TELNET, WHICH PROVIDES POINT-TO-POINT RECEPTION SECURITY.
IT ALSO USES SOME FANCY ALGORITHMS FOR ROBUSTNESS IN THE UNSTABLE
WORLD OF SOUND-CARD MODES, BUT NOT NECESSARY TO DISCUSS HERE. BOTTOM
LINE: IT IS A VERY USEABLE PROTOCOL FOR A SOUND-CARD DRIVEN SYSTEM.
IT HAS BEEN DEVELOPED AS A LESS EXPENSIVE ALTERNATIVE TO THE PACTOR 3
PROTOCOL, BUT IT IS NOT A REPLACEMENT FOR PACTOR 3. IT IS A LESS
EXPENSIVE OPTION FOR VOLUNTEER MARS MEMBERS TO UTILIZE IN ORDER TO
LOG-IN TO THE MARS WINLINK RADIO E-MAIL SYSTEM.
4. WINMOR, LIKE PACTOR, IS A POINT-TO-POINT PROTOCOL. IT IS NOT A
BROADCAST FEC PROTOCOL SUCH AS MT-63 OR OLIVIA. IT ALSO IS MUCH
FASTER, AND IS CONSIDERED A DATA TRANSFER PROTOCOL RATHER THAN A
NETWORK BROADCAST MODE. WINMOR IS AN HF RF NODE INTO THE INTERNET
SMTP MAIL SYSTEM, AND HOPEFULLY, IT WILL PROVIDE AN OPPORTUNITY FOR
THOSE WHO HAVE NOT BEEN INVOLVED WITH WINLINK 2000 AND PACTOR 3, AN
OPPORTUNITY TO PARTICIPATE IN THE MARS WL2K RADIO E-MAIL PROGRAM.
5. THERE ARE TWO BANDWIDTHS FOR WINMOR: 500 HZ AND 1600 HZ. I SUGGEST
YOU SET YOUR PROPERTIES TO 'AUTO' SINCE THE BANDWIDTH WILL BE
CONTROLLED BY SIGNAL CONDITIONS, AND THE BANDWIDTH OF THE WINMOR RMS
SERVER.
  IMPORTANT NOTE : FOR THOSE USING WINMOR, PLEASE UDERSTAND THAT
PACTOR 3, LIKE OUR VOICE E-NETS, ESPECIALLY FROM OUR SERVED AGENCIES,
TAKES PRIORITY OVER ANY VOLUNTEER ACTIVITY. THUS, THE OLD ADAGE,
'LISTEN BEFORE YOU TRANSMIT' APPLIES HERE. WHEN AND IF YOU HEAR
PACTOR 3, WHICH IS SHARED WITH PACTOR RMS'S NNA3VA, AAD4FL, AAE4TN
(TEMA), AND AAB9CA, PLEASE STAND DOWN, IMMEDIATELY. THERE IS NO
RECIPROCITY ON HF RADIO, SO, PLEASE UNDERSTAND THAT YOU MAY ONLY HEAR
ONE SIDE OF ANY TRANSMISSION BETWEEN TWO STATIONS.
6. TO RECEIVE THE WINMOR CLIENT PROGRAM 'RMS EXPRESS,' PLEASE JOIN
THE WINMOR YAHOO REFLECTOR: HTTP://GROUPS.YAHOO.COM/GROUP/WINMOR/
(JOIN AS MARS, NOT AMATEUR, PLEASE.)
7. BELOW IS SOME INTERESTING INFORMATION FOR YOU TO REVIEW. WINMOR IS
JUST IN FRONT OF PACTOR 2 AND BELOW PACTOR 3, ALL THINGS NEVER BEING
EQUAL. (THE COMPLETE WINMOR PROROCOL SPECIFICATION HAS BEEN POSTED ON
NAVYMARS.ORG UNDER THE WINLINK 2000 INFO TAB.)
  ARQ POINT-TO-POINT:
    PACTOR-1: SL2: 200 BD, 128 BIT/SEC,  256 WPM (500 HZ).
    PACTOR-2: SL4: 100 BD, 589 BIT/SEC, 1178 WPM (450 HZ).
    PACTOR-3: SL6: 100 BD, 2720 BIT/SEC, 5440 WPM (2200 HZ).
              SL5: 100 BD, 2039 BIT/SEC, 4078 WPM (2000 HZ).
              SL4: 100 BD, 1186 BIT/SEC, 2372 WPM (1800 HZ).
              SL3: 100 BD,  589 BIT/SEC, 1178 WPM (1800 HZ).
    WINMOR 'AUTO MODE' FROM 450 WPM TO JUST ABOVE THE SL3 PACTOR 3
LEVEL.
  NOTE: WITH WINLINK 2000 AND ITS B2F BINARY COMPRESSION, THE
THROUGHPUT IS MUCH HIGHER.
