[Elecraft] K2 as a Subreceiver

[Martin]

Elecrafters,
my TS-850 has an output for hooking a transverter to the rx-path.
You can also hook up the Rx-ant input from the K2.


This is great for listening on 2 freqs simultaneously with a K2 
connected . One ear hears the K2, the other ear hears the TS-850.
There is no danger to transmit into either radio directly.

Would you give me advice how to protect the K2 from overloading when the 
other radio transmits on the same band?

Break the connection to the K2?s rx-ant input?
Ground the connection to the K2?s rx-ant input?
Switch the K2 to transmit with power set to minimum?
Mute the K2 somehow?

Or a combination of this?
