[wxsig] data string format

One of the problems I had with my T238+ was that the audio output from 
the modem was not high enough for my radio.  With a lot of help from the 
members of this forum I was able to run down the problem and implement a 
fix.  It involved changing a resistor and capacitor as described in the 
following page:  
http://lists.tapr.org/pipermail/wxsig/2007-May/000557.html.  Once these 
changes were made I was able to get a solid audio output that worked 
with my radio. 

Hope this helps,
