I wonder. One curious fact supporting this is the noise blanker drop factor. This is the proportion of time the blanker is active. The drop factor is always a bit higher on the new rx than the old wh

The old rx is down at the moment, being measured on the work bench. The system noise floor is about 140nV/m in 1Hz. That's very high but quite low enough for natural radio (for which it is mainly use

Merging the currents from multiple front-end devices is a conventional way to achieve ultra low noise and this looks like a good implementation. I tried this technique with two devices but the doubl
