Turn on the 15 db attenuator in the receiver or put a 20 dB attenuator 
in the line from your antenna to receiver.  If the key clicks continue, 
it is a good bet they are being transmitted.  If they go away, it is 
front end or mixer overload.

Thanks Don,
Using yours and others suggestions I determined it was the transmitter.

Ray,

It could be that the beacon is actually generating those keyclicks.
Try turning off the preamp in the K3S and or turn your beam so the side 
is toward the beacon.
Are the keyclicks eliminated?  If so, it may be too strong a signal into 
the K3S, but if they continue, they are likely being generated by the 
beacon.


Remember that the K3S has input protection.  In the form of a Carrier 
Operated Relay and has a mechanism to turn off the preamp if the signal 
is too strong.
If you tune to the beacon frequency, turn on the preamp and point your 
beam at the beacon do you hear the COR relay clicking in the K3S or is 
the preamp turned off automatically?  If so, that is too much signal 
into the K3S.

Probably an Icom, they are bad for key clicks.   Check his website or 
QRZ page and see if it says what he is using for the beacon.

Very unlikely. Is your Noise Blanker turned on? That can cause clicks. 
Otherwise, I'd say the beacon has REALLY bad clicks. Clicks should not 
be audible farther than 2 kHz from a signal, and even that would be 
considered dirty.
