[Elecraft] [K3] K3 and Ameritron AL-811H Amplifier

[Ian Kahn]

All,

I recently acquired a used Ameritron AL-811H for use with my K3 (until I
can save enough to get the KPA500).  I seem to be having issue getting the
amp to respond to key down on the rig.  I have an RCA cable running from
KEY OUT on the back of my K3 to the RELAY on the back of the amp.  I have
DIGOUT1 on the K3 set to ON.  The amp is configured for, and plugged into,
a 240V AC outlet.  When I go key down, either in CW or SSB, I only get a
plate current of about 120 mA and don't get any grid current.  I suspect I
have something misconfigured and the issue is operator error, but I'm at a
bit of a loss as to where to look at this point.  Can anyone offer any
guidance?

Thanks and 73,
