Gary, I will echo Lance's comment about the 6M preamp.
I had built a Down East Microwave kit ... a well thought of company here in the US ... and found the Elecraft PR3 to be equal, so sold the DEM preamp to a local friend and kept the PR3 because of it's easy integration into the K3. My only improvement observation .... the power / control cable is too short and keeps the preamp too closely tethered to the K3. It's easily unplugged from the preamp when moving the other cables to/from the back of the K3. 73!
