Regarding keying another amplifier from the KX3/KXPA100: There is a problem currently being addressed beyond the (electrical specs of current and voltage) capacity of the PTT line to key another amplifier. Currently the KXPA100 cannot be used to key an amplifier with slow frame relay TR switching. The SWR detection cicuitry in the KXPA is too fast to allow the external amp (non-QSK) to go to transmit without tripping out on "ANT FAULT". If you want to drive an amplifier with non-QSK relaying you will have to use manual PTT to key the amplifier to transmsit before giving it any RF power. I understand our Heros at Elecraft are working on incorporating a menu adjustable timing delay to allow VOX keyng without the ANT FAULT problem.
