QSK requires that an outboard linear is somehow switched into transmit mode, preferably before RF arrives at its input socket. In the case of my TenTec Hercules II amp, a control signal is fed back to my Omni-V to tell it the linear is ready to receive RF drive. The Hercules uses a vacuum relay; there are fast and slow QSK options built into the Omni-V. Will the K3 accommodate this kind of interlocking ? _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
