[Elecraft] K3 2nd receiver filter question

[Darwin, Keith]

Just like the main receiver, the 2nd RX comes with the 5 pole 2.7 KHz
filter and has spaces for others.

If I order the 2nd receiver, do I need any additional filter for the 2nd
receiver?
I know that I can add roofing filters, but I am not sure if one is built
in.
