As author of the column, my response is, well, yes and no :-) There's an 
item about a BCI filter for the Pixie transceiver. I did some computer 
analysis on the author's design and suggested some improvements. But after I 
had submitted the column to the publisher I had a "Doh!" moment. I realized 
something about the original design that I probably should have recognized a 
lot earlier. (But whether it really makes a lot of difference is probably 
open to debate.)



In any event, there's probably going to be someone who reads my commentary 
on the filter and mumble that I don't know what I'm talking about, and/or 
that there's a lot more to it than I realize. And of course they would be 
right. I am not an engineer and also don't design, prototype and test 
filters at work, so of course there are gaps in my understanding of things. 
If anyone is an RF engineer and/or designs filters a lot at work, I'd love 
to discuss this particular issue with you! (And yes, there will be an update 
in the next issue of the column.)
