The adaptive morse code terminal unit is a revisit of an old idea 
which I had developed into a product back in the 1980's.
 
The basic idea was to construct a hardware interface for the reception 
and transmission of morse code  (not a new idea in itself).  
The innovative part comes in where the software begins. The idea 
is to make the software adaptive , in that it makes adjustments 
to the hardware while translating morse to text,  and text to 
morse.  The most stunning feature of the software was it's ability 
to adjust to conditions of excessive QRM and QRN, and to copy some 
morse signals that the human ear could not extract from the noise.
 
 
The original 80's version required an external interface , and a 
Commodore 64 computer.  This more modern version requires only a 
dumb RS-232 compatible terminal to send and relieve morse code.  
(Some of the more exotic features of this device require software running on a pc.)
 
Features: 
   Full duplex operation  (fast QSK is no problem )
   Automatic speed adjustment
   Automatic reconstruction of continuous wave transmission audio signals damaged by sferics.
   Simple and easy to use interface
 
The circuitry includes a PIC18F252 microcontroller ,  external active filtering,  
input amplitude, and audio tone demodulator frequency are under computer control.
