[Elecraft] Curious -- why is KXFL3 roofing filter an option on KX3 ?

[Phil Hystad]

Phil,

I concur -- in my second reply to Wayne, I truncated the first sentence (I think it was the first) and the result was not very meaningful.  I had originally written something like "...but then when I bought the KX3 I ignored the price as I really wanted the KX3".

I cut that out because I didn't want to let Wayne think that I would buy anything at any price -- well, maybe I would almost but I did really want the KX3 for portable ops.  Now, I am wondering if I should keep my KX1.  Oh, I will keep it but it is not being used anymore.

First, I already own a KX3 with the KXFL3 filter so I am not asking this in order to choose to buy or not.  Caveat:  I am also a neophyte (philistine, ignorant, or troglodyte) in this sort of radio technology and still in learner mode.

Without it, as I understand the function, any crowded band interval like a pileup or close-in CW signals and such would render a KX3 (without the roofing filter) with less than the usual Elecraft stellar RX performance.
