My K3 includes the KRX3, KAT3 & KXV3A. On 160m and 80m, I use a shunt fed tower for TX/RX and a separate RX loop that goes through an RF limiter and external preamp to RX ANT IN. For Diversity RX, the loop has to be connected to AUX RF but it's then not available to the Main RX. In order to have the flexibility to use the RX loop with either the Main RX or the Sub RX for diversity, I built a switch box to route the loop to either RX ANT IN or AUX RF. A HOLD of the K3's RX ANT button toggles the antenna input to the Sub RX to the correct BNC.
I considered using ANT2 on the KAT3 but it wasn't obvious that I could achieve the same flexibility. Other solutions to allow the RX loop to be available for both the Main RX or the Sub RX in diversity mode? My tower and RX loop are very close. The RF limiter protects the RX front ends from QRO. Caution! Your situation may be different. While in diversity RX you can operate split and also check your TX frequency with the REV button. Then use VFO A to find your spot. A very elegant design feature! 73 - Steve WB6RSE ______________________________________________________________ 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
