Bill -
I have built and am actively using a Softrock Lite II for K3 IF kit.
These kits are not currently being sold by Tony, but the kit is a Softrock
Lite II for 40 m with a different crystal and several other small changes in
caps and toroid windings. I do have the Instructions for the kit. I believe
some hams have bought a custom crystal to adapt the Lite II for 40 m to K3
IF. The kit works best with the Clifton Labs Z10000 Buffer Amp. This is
available as a kit and is inexpensive.
A slightly more expensive, but easier solution is to buy the LP Pan. It
comes as a kit $175 or built $225. The kit is a very easy build. The
instructions for the LP Pan are excellent. They provide all the detail you
need to build the kit, select an appropriate sound card, set up the cabling,
obtain and set up the software. If you can read and follow instructions, you
can make it work.
Power SDR IF played with either of these panadapters provides up to 192
KHz of visual display. It provides a second receiver, even if your K3
doesn't have one. It provides point and click tuning on both VFOs. It
provides point and click filter adjustment for both VFOs. It allows you to
listen to VFO A in 1 ear and VFO B in the other. Sliders allow you to adjust
how you hear VFO A and VFO B. And more. All of this is point and click and
fully, bidirectionally interactive with the K3. The visual display adds
dramatically to the enjoyment and functionality of the K3.
If you want to discuss this further, please contact me off list.
K4KGG, Larry
