NICE!  Thanks for posting that.  I just ordered one, also in 80M.  It was $55.30 shipped.  I don't know how they make any money with the prices they charge.  Shipping was cheap enough that I assume they are in the U.S., but I can't find where they are located.

This will be a nice fall project.  Naturally I'll design a 3-D printed box and make a few available for members here that have been around a while.

Awesome Bob. By the way I have made the Nescaf filter, and the video is set aside for when I won't have anything to post on Youtube. The only issue with this new kit is having to cut a rectangle window in an aluminum case... Oh well... Other than that it's great!

Looks like I have serial #254.

I also wondered about that. This is what I found out. The owner of QRP Labs is a British ham:

Gil, I can't wait to hear what you think of the filter.  I built my filter and Pico-Keyer and but haven't quite finished the box to put them in, so I haven't tried the filter yet.

Sparks, thanks for the background on  I got the sense they were from across the big pond, which makes the low shipping cost impressive.
