New release of MULTIPSK (4.34)
Pour les francophones: la version en français de ce message se trouve sur mon site (http://f6cte.free.fr). Il suffit de cliquer sur le lien "Principales modifications (courriel avertissant de la sortie de la nouvelle version)".
The MD5 signature of the downloaded MULTIPSK_setup.exe file to, possibly, check (with WinMD5 for example), that the downloading works without error, is equal to: 3d1752e8c4b54cd2da3b908d9d17e1
Multipsk associated to Clock are freeware programs but with functions submitted to a licence (by user key).
The main improvement of MULTIPSK 4.34 is the following:
ARQ FAE is separated from ALE, the ARQ FAE becoming an autonomous protocol of 141A and ALE400 modes.
"ARQ FAE" means:
· "ARQ" for "Automatic Repetition reQuest",
· "FAE" for "Fast Acknowledged Exchange".
The ARQ FAE protocol stems from ALE protocols. It permits QSO fast and error-free in 141A and ALE400 modes.
ALE400 mode is specific to Multipsk. It is a MIL-STD-188-141A mode but transmitted in 50 bauds instead of 125 bauds and in a 400 Hz bandwidth instead of 2000 Hz.
The transmission and the reception are managed as in Packet (connected modes). Simply type the text or insert a sequence (macro) in the editor window and the text will be send. The associated protocol will allow the user to establish a fast link and to exchange with another Ham, still in in linked state:
· conversation (chat) error-free messages,
· small photos,
· mails with ou without files (small compressed pictures, for example),
· APRS positions, with automatic display on the APRS map.
The characters exchanged are 8 bits length so as to permit exchange in all ASCII-ANSI languages (English, French, German, Russian...), but not those with ideograms (as Japonese).
This protocol is not standard and does not exist in the FS 1045A specifications.
Note: there is a PDF document which goal is to show from Multipsk snapshots how to do the basic operations in ARQ FAE. This document is available from my site http://f6cte.free.fr/ARQ_FAE_
