I have connected a magnetic loop antenna on ant 1 connection and a yaggi antenna on ant 2 connection.
when I transmit on the yaggi ant on connection 2 (1 kw) , some of the signal from the yaggi antenna will be recieved by the magnetic loop antenna and go to the ant 1 connection.
The power going to antenna 1 connection seems to be abt 2-3 watt.
Is that a problem ?
How much power in, can ant 1 connection tolerate, when I am transmitting on antenna connection 2 ?

The isolation between ANT-1 and ANT-2 is about 60 dB. The isolation between the RX-A and any of the ANT-x ports is much greater.
The SCU has a signal overload protection relay that will disconnect the RF signal path if too much RF energy is getting to the SCU. I doubt that 1-2W or RF is getting to the SCU.
With the upcoming release of SmartSDR v1.5.0 you will be able to operate in Full Duplex (FDX) mode and in the software manual will be a set of equations that will provide a way to calculate the RF signal levels based on antenna isolation, preamp settings and RF power transmitted.1
