Hi Lee

There are 3 connectors (1/8 stereo ?) in a row on the left side marked ACC, 
KEY, PHONES.  The first connector marked ACC gives RS232 access.  Since it 
is not the traditional 9 pin RS232 connector (which would be rather large 
for such a small radio) a special RS232 cable is required to interface with 
an external computer.  A stereo plug could carry data in/out quite 
easily.  It also mentions that the KX3 uses the same commands as the K3.  I 
assume that digital/control software like MixW would be able to work with 
the KX3 in much the same way as the K3.  In addition to these 3 connectors 
there are 2 more (1/8" stereo ?) connectors ... one for the Mic/PTT and RX 
I/Q which could be used for other interesting functions ... like a 
pan-adapter ?
