Hello to all Ham and SWL,


The new release of MultiPSK (4.45.1) is on my Web site (
The mirror site is Earl's, W8BR:

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 improvement of MULTIPSK 4.45.1 is the following:


M20 radiosondes decoding


The new M20 radiosonde is an improved version of the M10 model. The M20 and the M10 radiosondes share the same description. However, there are differences between addresses of the pieces of information.


Note: Multipsk decodes the radiosonde position but not the telemetry (temperature, pressure etc).


This mode is available for licencied copies, only (otherwise, the decoding is stopped after 5 minutes).


Other improvements:

·                     For BPSK, QPSK, PSKR, PSK63F and MFSK modes, it is proposed a UTF8 characters decoding function (only in RX, not in TX, and limited to 2 characters). The "UTF8" button must be pushed, in case of UTF8 (Fldigi) transmission, i.e. if odd double characters appear instead of accented characters.

·                     Improvement of the RX/TX screen resizing.

·                     Possibility of a 4 times bigger waterfall or spectrum ("x 4" button).

·                     The receiver maximum frequency managed by Multipsk via Commander moves from 4.16 GHz to 24.3 GHz.

Note about translation of Multipsk.exe and Clock .exe:  the 4.45 version of Multipsk has been translated to Spanish by Joachin (EB4Z), from French.

I can confirm that the enhanced Frequency Management is working fine! :)
Thanks for the quick reply!
