Hi Wayne
Whatever amplifier comes from the Elecraft stable, a useful accessory would be a hybrid combiner to combine 2 or 4 Elecraft amplifiers. This appears to be a favored option for military HF users.

There will also be several SDR transmitters released very shortly by various people onto the market. All these SDR transmitters will be low power and less than 1 watt. A low drive option of either 100-300mw, 10 watts, 100 watts or 200 watts maybe with an attenuator input would be nice option.
It would also be nice to be able to reduce TX power in 3db steps using an attenuator. This option could also be used by MARS operators who use Rockwell HF80 or Harris 100 to 300 MW TX drivers especially if low drive is an option.
If the stock K3 at 10 watts could be biased for class A it would make a very good driver for the above amplifier. Can the K3's 10 watt PA handle class A bias? 2 or 3 watts of Class A power would be a nice menu option.
