[Elecraft] K2 Antenna Questions

[MyFord at nc.rr.com]

I purchased my first Elecraft radio, which is a K2.  It has the auto antenner tuner, and some other options.  I have ant 1, ant 2, where tuner is and also antenna 50 ohm, and RCV Ant jack.  I have a couple antennas that I do not want to use tuner with, and was wondering which jack to use and then how to select it.

I am in the process of loading pictures of my K2, outside shot and inside shots, onto my QRZ page.  Please look and tell me what options I have too.

I think I have 160 addition, serial connector, antenna tuner, internal battery, and I don't know what else.

Thank you
