[Elecraft] K3 to Al-811 Amplifier

[Jim Bennett]

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:

Hope that helps.

An the Keying Cable that is in the back to the Relay Plug on the Al-811? I see an ALC Output and ALC Adjustment knob. But I probably don't need to use those. But then again I could be wrong. Has anyone used the AL-811 with the K3? Thanks in advance. Mark Griffin, KB3Z
