Eric has permitted such announcements, but limits them to one a month. You will see offers to build a K2 that come in that same category.
Personal comment -- I particularly like the 700 Hz CW filter in my K3. I got used to tuning the bands using a 700 Hz filter width in my K2, and opted for the 700 Hz roofing filter when it was offered. Yes, I find it nice for 'scouring the pileup' before switching to the narrower 400 Hz filter when listening to a pileup. YMMV, but it is an available option.

The advertisements for that particular brand of 700Hz filter are passed through my junk filter or I wouldn't have seen it. I'm surprised you didn't delete the entire advertisement. I guess I'm going have to add the phrase "limited production" to my filters. In the K3, as it comes from the factory you already have a 700Hz filter with the standard 2.7 or 2.8 filter. Just use the width control to set either of them to 700Hz. It may not have the same slop as the 700Hz filter in question, but when you are listening wide on the sub RX in the K3 the difference between 700hz and 1Khzis not that much.
