Eric,
The thing that makes the KPA-1500 most attractive from my perspective, and
surely others, is it's supposed SO2R ability. What other amps on the
market offer similar capability other than the SPE Expert 1K-FA (which is
only 1kW)? A KPA-1500 is domestic, so eliminates the extra steps

You simply connect the PR6 to the RX IN/OUT on the KXV3. To use it just tap
the RX ANT button. On RX your signal path will go from ANT1 or ANT2 as
selected to the RX OUT, through the PR6 and back in through the RX IN. On
TX of course it just goes out to the antenna you have selected.

The K3 was optimized from the ground up for high dynamic range (which

While using a wall-wart directly is probably not a good idea, you might
want to see what Terry (WA0ITP) did to solve the problem. Essentially,
he epoxied an LM7812 and heatsink to the back of a wall-wart, added a
couple of capacitors, and checked the output for any ripple.
