[Yaesu] Which filter ofr my 857?

[Gary Smith]

Okay, a time worn question to the group.

Amd going to buy a filter to install in the 857 for ssb everyday use, but which one?

The 2.3 khz add-on Yaesu filter?

Or one of the Inrad filters ssb, 2.3 or 2.1khz.

This rig will be in my mobile, am not a contester, just looking to lessen the rig (and my ears) from hearing adjacent frequency signals.

Kind of like the parking lot syndrome: no matter how far away form the other cars one parks, someone autoamtically parks right next to you.
  
Thanks to all,
