[Elecraft] [K3]: AM filter question

[Jim Lowman]

I was tidying up the shack yesterday, and came upon a box with the 
Elecraft label.
Curious, I looked inside and found a couple of wire antennas from PAR 
Electronics that I bought at Dayton and not one, but two, 6 kHz AM 
filters for the K3.

Apparently I didn't install one when I ordered the FM filter, which also 
works for AM, and bought another at some point in time, not realizing 
that I had one already.

I do have the KRX3 2nd RX, but can't really think of an occasion where 
I'd need to work split with AM.
If not, I'll have one for sale, NIB.  I think that someone said $115 is 
a fair price?
