Lance, It would be wise IMHO, for those using CW in SSB (or any other VHF/UHF gear) and also having a sequencer, to use the TX INH input on the ACC jack to inhibit transmit rather than asserting PTT at the end of the sequence.
Yes, the K3 works a little differently than many other transceivers, but the TX Inhibit function was well thought out explicitly for use with a VHF/UHF sequencer. You will likely have to add a pullup resistor to +5 volts the TX INH line, but that should be an easy task, especially if a source of +5 volts is available in the sequencer logic. 73, Don W3FPR On 2/1/2012 4:48 PM, Joe Subich, W4TV wrote: > On 2/1/2012 2:23 PM, W7GJ, Lance wrote: >> One thing that disappointed me is that this very useful cross-mode >> feature (at least on 6m, where I do most of my operating), is >> available only if you are running VOX mode. >> >> I am not sure why it has been excluded when you run with a footswitch >> or sequencer to trigger the PTT line. > The answer is quite simple, the PTT line engages transmit in the mode > set by the "mode switch".
