You can use a splitter or a simple T-connector. Connect RX ANT OUT to the center port and RX ANT IN and the SDR to the "side" ports. Of course, with a T-connector, all 3 ports are equivalent. Then turn on RX ANT from the front panel. You lose 3 dB but that shouldn't be much of an issue on HF.
Yes, IIRC the Operator's Manual for K3 includes a good antenna routing diagram. /Rick N6XI On Mon, Nov 18, 2019 at 8:08 AM Dave Cole <[email protected]> wrote: > A few years ago someone posted a method of using a splitter, and the > External Antenna jacks to feed an external SDR with the direct antenna, > not a IF, but a wideband signal from the primary antenna... > > I think it was something along the lines of add a splitter, between the > RX Antenna in/out, and then picking off the antenna feed to the SDR from > an output of the splitter...
