Sensitivity below 700khz
I have two Kiwi's with the antenna jacks paralleled. My antenna is a W6PLVP loop being used to couple signal from a 240' tower. Antenna works great but the two SDR's have dismal sensitivity below about 700khz. I added a third SDR to the antenna and it is receiving stations very well on each frequency from 530 on up yet the Kiwi's hear few signals. Was not always this way. When I relocated the receivers, the coaxial connectors were torn from the boards and the screw terminals are now being used. Was there a software update that could have affected the sensitivity ? The S meter stays S9 across the AM band when the antenna is removed. S meter calibration is on 0db. That seems unusual. Anyone been down this road before ?
