Mike, I have the KRX3 installed in my K3 with antenna connected to Aux antenna jack. I have not connected another HF antenna while operating on HF so do not know if there is danger to the sub-receiver. I thought the KRX3 also had some diodes protecting the input from extreme RF levels.
You need two antennas to operated diversity reception. With both receivers sharing a single antenna all you accomplish is being able to receive split (which may be nice in some circumstances). I use my KRX3 to receive a horizontal polarity 2m signals when the main receiver is receiving vertical polarity. Special sw takes both signals and is able to strip out the actual polarization angle and optimize the signal to that polarization. It called dual-polarity adaptive reception. One could accomplish the same for HF by using two dipoles strung at right angles to each other and adding one quarter wavelength of coax to one dipole. The two dipoles then are quadrature phased and one can detect circular polarized signals. In fact nearly all HF is CP after passing thru the ionosphere. 15m thru 6m is easy to set up with such an antenna (due to smaller size). 73, Ed - KL7UW ______________________________________________________________ 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
