Using K3 with AMP

[K4GM-George]

For several years I keyed my Dentron Clipperton L amp from the jack on
my Pro II. I did not use any buffer and it always worked fine because
the voltage/current being keyed are w/i limitations of the Pro II.  
Without powering up the AMP I ran a cable from the AMP to the jack on
the K3 I just received.  I noticed that WITHOUT AC power to the amp when
I moved the standby switch to operate the K3 PTT was keyed and the rig
put out normal power.  This is w/o the AMP being ON.  Any thoughts from
anyone? I do have an AMPKEYER available to use between the units but
thought I could key the AMP  directly. Why would my STANDY/OPERATE
switch on the amp operate as a PTT switch?  Do I need to set a parameter
in the K3?  Of course all equipment share a common ground connection.

73, K4GM George

George,

What K3 jack are you connecting the amp to?  You should be connecting to
the KEYOUT jack.  If you have connected to the K3 PTT input instead, I
could understand that you might have difficulties like you describe.

Or to the "KEY" input next to it, it if was in CW mode...
