In theory (I have not tried it), one could send an AI2; command to the Master K3, to enable "AUTO INFO mode 2," then connect the two K3s to each other using a male-to-male null-modem cable (pins 2 and 3 crossed). Then the Slave K3 should track the Master K3.
To get a logging program working on Master, you may want to use a K3S (or K3 with KIO3B upgrade), using the USB port used for the logger control, and connect the RJ45 to DE9 "pigtail" to the Slave via a "one-way" null-modem cable. Pin 2 on the pigtail (Master) would be connected to Pin 3 on the Slave. Pin 5 (GND) would be connected straight through. Do not connect Pin 2 on the Slave to Pin 3 on the Master, so the communication is only one way: Master to Slave. Note: AI2; mode doesn't output every movement of the VFO knobs. It only sends the new frequency to the other radio when you stop turning the knob, so the slave tracking would not be instantaneous; there would be a delay. Another option would be to try the experimental "Tracking" feature of a microHAM MK2R+ (firmware 7.5 or later). 73, Bob, N6TV On Tue, Mar 19, 2019 at 11:37 AM Igor Sokolov <ua9...@gmail.com> wrote: > I wonder if somebody knows of an easy way to make a pair of K3 (both > with subRX) work in master-slave mode.
