Interestingly enough I have something like that happen now and then as well...
I am driving the K3 directly with a serial port from my computer, and in DATA A mode, so far only when in DATA A. I operate 90% in DATA A so take that last one with a grain of salt... Although it has never happened in CW mode. Once the problem has been triggered, if I tap the XMIT button and it drops out of transmit. Next time, I'll try a different button... I am using no interface... -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Sun, 2014-07-13 at 19:01 -0700, Dan Sherwood wrote: > I have discovered an issue with my K3, (ser 5820). > > When using my Tigertronics Signalink USB device, the unit keys the rig fine, > but when the interface unkeys, transmission ceases, but red XMIT light stays > on and reception is muted.
