[Elecraft] K2 #7997 is alive

Sun May 9 17:39:15 EDT 2021

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

tnx & 73, Doug -- K0DXV

>> 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.

My K2 has gotten a lot of mods and updates but still needs a number more to get more up to date.
