[Elecraft] Transmitting while listening in diversity mode

[Arie Kleingeld PA3A]

Tony,

Most of the time I work in diversity on 160 and 80  when in contest.
I tested the antenna setup by transmitting in one antenne and measure 
the power delivered by the other antenna to a 50ohm resistor.
As long as the power (worst case situation) is low enough (I use a 10mW 
limit)  there's no problem.

(BTW, for the people who want to know, my powermeter can measure from 
-50dBm to +30dBm)

I'd like to add a question: what do other people use as a limit?
