Also make sure that your rx antenna is not running over ground radials from tx antenna73 Ken K5DNL

I am surprised that the front end protection would kick on with that much
RX antenna spacing and only 50 watts unless there is another way RF is
getting into the shack. If that is what's happening I concur with W3FPR.
Another option would be a receiver overload protector such as

I suspect that increasing the TX Delay will *not* fix that problem.
Since at greater than 50 watts, you hear relays clicking indicates that
the K3S COR is being activated.
The solution is to either move your RX antenna further from the TX
antenna or use some device that disconnects or grounds the RX antenna
while transmitting.

point to TX antenna is around 200 ft. Over 50 watts I hear relays
clicking and stations have a hard time breaking in even using QRQ plus.
I assume the RX antenna is not switching fast enough and I'm getting
milliseconds of high RF into the front end and protection relays are
kicking in???
