(updated October 16, 2011) NEScaf filter kits are in stock.
The first thing that I put on my NEScaf board was a diode - in the hole for the +ve power lead. Too darn easy to get the power leads wrong!
And then I started playing!!
Discovered that when I used the filter for RTTY, it appears to work about the same as my 250 hz 8.8mhz filter - as far as the waterfall is concerned anyway. Of course the crystal filter will have other benefits - and is a lot pricier....
Where do I get a replacement for the big chip on the board? The switched capactive filter. Can I get one from NEQRP club?
HI all,
I just completed building my NEScaf and it is working great! I connected it to my Elecraft K1. I might also use it with my "tuna can family". Thanks for providing a nice kit.
