[Elecraft] 2nd Receiver RF Protection

[K3RWN]

I was searching the archive tonight and read several emails regarding
protecting the 2nd receiver while using a RX ant.  However I did not find
anything related to protecting the 2nd receiver when connected to the AUX
jack.   I do use a 419B band pass filter to protect it from my other
transceiver.  Are there any concerns when the 2nd receiver is connected to
the AUX ant jack with the RF from the K3?
