K8IQY’s Stable and Sensitive SS-40 40M Receiver Kit

Anyone who has looked me up on QRZ or who has been following this blog for a while will be aware of the fact that one of my most prized home-built kit rigs is the Norcal 2N2/40. It’s a great little performer, and after I sell my FT-817 (which I plan to do soon), will be my main radio.  I key it with the AA0ZZ EZ Keyer from 4SQRP and it’s a lot of fun to use. The best thing about the 2N2 series of radios is their low-noise receivers. On top of that the kit was very well produced – great circuit board and excellent documentation, making the process of putting it together an extremely enjoyable one. Imagine my interest when I discovered yesterday that Jim has designed a low-noise receiver for 40M which is available as a kit for just $50 from 4SQRP. It’s called the SS-40, which stands for Stable and Sensitive, and you can get it here.

Boy, am I tempted! The following picture is from the website of 4SQRP. I keep telling myself, “I do not need another 40M receiver.  I do not need another 40M receiver, I do not need…………..”



  1. Selling the 817..bad move !!…sell an HT instead…sell next doors cat….anything but the 817

  2. I’ve had 9 really good years with the 817 – time to move onto something else John, but appreciate the sentiment. It’s a really good “do-it-all” radio.

  3. Dave, I’ve been repeating to myself for a couple of days the same “I do not need another 40M receiver. I do not need another 40M receiver, I do not need…………..” Yesterday I filed my order for one 🙂

  4. I’m thinking that this receiver, along with the NS40 xmitter and the K8IQY Magic T/R switch would make a killer combo – to build, look at, and use.

    Visiting your blog is beginning to cost me money…
