[Moon] MAP65 status report

[Joe Taylor]

Dear EME Friends,

A month ago I mentioned here a piece of SDR software that I 
have been working on, tentatively called MAP65.  Many people 
have written to ask for more details.  I have consequently 
placed a status report and a MAP65 screen shot on the WSJT 
web site.  Links to them are given below.

Very briefly:

MAP65 is the "back end" of a a wideband receiver optimized 
for JT65 signals.  It works together with Linrad and 
suitable RF hardware to provide automatic 
polarization-matched reception of all detectable JT65 
signals in a 90 kHz passband, in real time.  The program 
runs under both Windows and Linux.  In the future it will 
probably work with Winrad, as well as Linrad.

The present state of MAP65 can be judged from the screen 
shot, which was produced by processing 10 minutes of data 
recorded on November 11, during the second weekend of the 
ARRL EME contest.  In those 10 minutes, MAP65 decodes nearly 
50 callsigns of EME stations operating between 144.100 and 
144.160.  My EME antenna at the time was a pair of 2MXP20 yagis.

MAP65 has not yet been used "on the air".  My EME antenna 
was taken down just after the 2006 ARRL contest, and its 
replacement will not be erected until warmer weather arrives.

The MAP65 Status Report and Screen Shot can be found at:

Like WSJT, MAP65 will be "Open Source" software.  I hope 
that these small tidbits of information will entice some 
others to participate in the program's development.

With best wishes to all,
