I used an AL-811H for many years with my K3. Coax connection and PTT is all that is needed.
Some other things to think about: - Ameritron 811H only need about 60 watts or so to drive it. At the beginning, I ran about 100 watts into the amp, but after a few years I noticed that the finals had silvery spots on the grids. That's because I was over driving the amp and melted the them. Only use enough in to get the required out. 60 to 70 watts is plenty on that amp. Harold "Marty" Fitzgerald W5MF [email protected] Not an AL-811, but I've used an AL-1200 with my K3. I used an RCA cable for amplifier keying and a PL-259 jumper for RF. I did not connect ALC, I instead adjusted the K3's power output as appropriate. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Friday, December 13, 2013 10:02 AM To: [email protected] Subject: [Elecraft] K3 to Al-811 Amplifier Hi Guys, I would like to hook up my K3 to an Ameritron Al-811 Amplifier. I assume that I connect the K3 output to the Amplifier Input. 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.
