Hello to all Ham and SWL,


The new release of MultiPSK (4.43.1) is on my Web site (
The mirror site is Earl's, N8KBR:

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:


Multipsk associated to Clock are freeware programs but with functions submitted to a licence (by user key).


The main improvements of MULTIPSK 4.43.1 are the following:


·                     Addition of the Contestia 16-250 sub-mode + its RS ID (number 275).
This sub-mode can be used under a noisy channel (minimum signal to noise ratio of -15 dB) with a reasonable characters transmission speed, of about 20 wpm.

·                     Decoding improvement of ACARS, SYNOP, EGC and VDL2 modes.

·                     Addition of two prediction functions in the "Satellites" window:
- over time "Advance" function, to see the satellites trajectories in the future, up to 4 h,
- minimum distance in km/miles + azimuth and elevation at the shortest distance between the satellite and the user.


Other improvements:


·                     "Knots" unit added for HFDL, ACARS, VDL2, AERO, ADSB modes.

·                     Integration of the rsp_tcp.exe V.1.1 file for the Multipsk interface with the SDRplay RSPdx receiver. However, the SDRuno version 1.4 program must be installed. For more information, see:


Note about translation of Multipsk.exe and Clock .exe:  the 4.43 version of Multipsk has been translated to Spanish by Joachin (EA4ZB), from French.
