KX3 HF Band Decoder

Having had a KX3 for nearly 6 months now, the biggest handicap has been the lack of band outputs to switch external equipment (eg LPF in external PA, antennas etc).  These are standard on the K3 but are missed on the KX3. So Today I finished rewriting and testing the code for my RS232 Transverter driver to accomplish this. The writeup is at http://g4fre.com/KX3_RS232_hf.htm
