Hi Larry, I don't think it is very hard. The band data of the 817 is a dc voltage between 300 mV and 4 V dependent on the band. I think a pic decoding the KX3 RS232 data and driving a DAC for generating the voltage would probably do the job.
Maybe this page http://g4fre.com/KX3_RS232_hf.htm is a good starting point... 73 Ralf, DL6OAP Am 17.07.2013 um 23:15 schrieb Larry Hagood <[email protected]>: > I would like to use a small (40 watt) amp with my KX3 when the 10 watts just > won't cut it.
