   Hi Eric,

   Great idea, but the KX1's final amplifier operates class C. To make the 
   KX1 transmit on SSB would require class AB PA bias and the addition of 
   a balanced modulator. This is not readily accomplished with either 
   internal mods or an external adapter.

   However, it may be possible to operate the KX1 in any low-data-rate, 
   dual-tone FSK mode. This is compatible with a class-C final amp, and 
   should require only a firmware change. The KX1's key jack would serve 
   as the data input/output port for connection to a computer. 
   Unfortunately FSK (e.g. traditional RTTY) is not quite as popular as 
   PSK31 for QRP use, even though good reliability is possible with some 
   variants.

   Would this be of interest?
