Hi Mark - I used an AL-811 along with my K3 for almost a year. It works fine, and the only two cables you need are the coax and the PTT line. ALC connection is not recommended. Also, you will need an RF power meter between the AL-811 and your antenna (if it is resonant), or between the AL-811 and your antenna tuner, if the antenna is NOT resonant. And don't forget, disable the K3's internal antenna tuner, if you have that option installed. There is a very good and helpful AL-811 tuning web page out there. The URL is:
