A little back ground,, The effort started as a result of my using WWV at 15.000000 MHz for calibrating the reference oscillator. Tuning from 14.999999 to 15.000000 MHz I noticed a 9 to 12 Db drop in signal strength of WWV.
I could hear relays’ switching at the 14.999999 to 15.000000 MHz boundary. This lead to making a list of (“suspected”) switching points by tuning from low 1MHz through 30MHz listening Looking at schematics of the KBPF3/A I heard switching at some points that did not make sense, with the 14.999999 to 15.000000 MHz boundary being one. It is not easy to probe the KBPF3A in my K3S-100 to check which relays are bein set/reset because of the installed KRX3A. I have a K3S-10, but will need to install a KBPF3/A to check the 14.999999 to 15.000000 MHz boundary and gather the information.
