Exactly what I hope to do. I have the original RSP1 which is a pretty
decent receiver. I often pair it with an old Swan 270 for a transmitter.
Kinda fun.
My problem is age. My hands are not very steady these days. I've had
some nerve damage in my dominant hand. I can barely sign my name.
Fortunately, I can still type pretty well. So.... Is there anyone that
would be interested in performing this mod on my K2? Happy to pay time
and materials if someone can handle this. Let me know off list. (doug at

Yep. I am working toward adding a panadapter to my K2 using the IF buffer board from DX Engineering and probably a SDRplay RSP1A. I have a $25 RTL-SDR stick I'm experimenting with but I don't think it'll have the necessary performance. Here are the links:

Doug,
I have a write up here: https://www.w8fgu.com/k2pan.html for using a
SDRPlay unit and HDSDR software to make a panadapter that works pretty
well on the K2. It requires the IF Buffer amp designed by Jack Smith,
K8ZOA (SK) and sold by DX Engineering to be installed in the K2 to
provide K2 IF output for the SDRPlay unit.

I'd love to find and do the mod that would let me use a small SDR receiver as a
spectrum display. I've been spoiled by this extra dimension that is becoming
common on new transceivers. My K2 also has great sounding audio - I use a
small, efficient HiFi speaker - something that Radio Shack had many types of.
Minimus I believe they were called. And I use a Heil mic or a Kenwood MC60 and
I get great audio reports. Not to make Wayne's ears burn - but, personally, I
think the K2 is an absolutely brilliant design. Of course the K3 is also and no
doubt the K4. But to design a kit that anyone handy with a pair of snips and a
good soldering iron can build on a kitchen table - that's a special brilliance.
I hope a lot of K2s live on and still get used regularly.

Totally agree. The last K2 I built it keeper. It's a FB rig with great
sounding RX that holds up well in tuff cndx. FWIW, it's also happens to be the
first and only K2 I've built. That was in Dec '00 when the the Elecraft
reflector was all builders, homebrewers, experimenters, QRP CW ops... It was
great fun. My K2 has gotten a lot of mods and updates but still needs a number
more to get more up to date.

I've built 5 K2s. The last one is a keeper. I built several for other
people. I still get a kick out of turning it on and making contacts with
a "kit" radio. Mine is a 100 watts, ssb adapter and the outboard tuner.
Wired for a Kenwood hand mike. I often think that if it was the only rig
I owned I would be completely satisfied. Receiver sounds great and I get
great audio reports. If anyone has ever considered building one - go for
it. The satisfaction of turning it on and making contacts with something
you put some serious time in to build is an experience I highly
recommend. I don't know if I've ever operated a better cw transceiver.
And even in a crowded band on 20, it can hold its own. I love it.

I'm 20 years late to the game but I finally built a K2. What a satisfying
project to build, and a delightful rig to operate. It doesn't have all the
performance and features of my fully-updated K3, but it's a great little
radio nonetheless.
I finished the final alignment and test Tuesday and have used it a couple
evenings now.
Now to build the SSB adapter and the 100 W amp.
