K3 Rx Port Isolation?

[Deni F5VJC]

I've recently connected my Beverage antenna to the Rx port on my K3. Works very well BUT... I'm getting some relay chatter when running 400W from my Amp to a vertical. I assume this is due to the coupling/proximity issues between the two antennas. I know the Rx port of the K3 is protected and has a C.O.R. but is there likely to be a damage potential here?
What is the best way to solve this problem?  I can't move the antennas! Fiters?
I have only tried this on 80M so don't know if the problem exists on other bands. Any advice appreciated.

Afaik, Elecraft is working on a modification to improve the isolation  
of the RX input - check the reflector archives. Apart from this, it is  
always a good idea to disconect an RX antenna while transmitting,  
which can be done, for example, using the PTT signal, a simple relay  
and a transistor.
