I have a K3 with the internal K144XV 2m module. This works FB but both TX and RX are on the same antenna port. In a configuration I am thinking of using, there would be separate RX and TX lines. With my main 2m EME station which uses a second K3 and a 10m to 2m transverter, I have it configured with 28 MHz TX out on ANT2 to the transverter input port and 28 MHz RX in on the RX ANT IN port with the front panel . This works FB. I have the XVTR PWR menu setting such that it outputs 3 watts which is directed to ANT2 rather than the XVTR OUT port. Even though I am using a transverter, I am not using the back panel XVTR IN and OUT ports. When I attach the output of a 144 MHz to 28 MHz downconverter RX line to the RX ANT IN port and enable RX ANT function on the front panel, the K3 with internal K144 XV 2m module does not give me the desired results. Ideas or suggestions?

I would think you can remove the jumper and use the header to make your receive connection Ken ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
