There are also two DIGI OUT lines that are currently, I think, uncommitted.
73, doug Date: Wed, 14 Jan 2009 21:55:23 +0000 From: Lance Collister <w...@q.com> Hi Dave, You raise an interesting question....maybe that is the elegant solution to integrating the K3 into old kluge-like VHF stations with lots of coaxial relays, homebrew amplifiers, etc. PTT output jack on the rear of the K3 could optionally be configured as a sequencer itself, so it would close an adjustable amount of time (up to a second) BEFORE any RF would be permitted to be generated after the rig is put into XMIT by either the microphone/footswicth or the serial port PTT lines. Certainly, this option would not be selected by those who want to work QSK! But they would simply not choose the option. If this option were stored by band, you could have a built-in sequencer only on certain bands, and QSK on other bands! With such an option, you would never have to worry about blowing anything up, regardless of how the K3 incoming PTT line itself was keyed ;-) What do you think, Elecraft?
