Here is some info for you and lrl builders about Tesla telluric currents or telluric waves or golden waves detector.
Long time ago it had been reported that Nikola Tesla made a device which allowed him to hear sounds at very great distances. I have never seen any Tesla's details about of the circuitry used by Nikola Tesla. But in 1986 year, american Dave Lawton has produced such a device, and he reports that he could hear human conversations taking place 4 1/2 miles away from him or 7,2 km. Interestingly, the sounds from 7,2 km were also travelling through a solid state stone wall some three feet thick cca. 90 cm.. The circuit for this device is described in Radio-Electronics Magazine in April 1986.
The circuit shown here comprising of two 741 operational amplifiers connected as a two-stage amplifier. The unusual feature is very small amount of white noise being injected at the piezo tranducer at input of op. amp. The white noise is generated by the 5 volt zener diode. The level of white noise is controlled by 1.5 Meg variable resistor, plus the 10K fixed resistor. While the range of these two components is 10K to 1.501 Meg. the working setting is normally very high and so only a very small amount of white noise is fed into the input of the first 741 op. amp. to modify the tranducer input. The adjustment of injection of white noise is the main control here, and it has been found experimentally, that when the tuning or pot.setting is correctt, the circuit has the feel the strange telluric echoes from positive op feedback. This device is is operated by turning the gain high up until the op. amp. just reaches self-oscillation, and then backing the gain off very-very slightly. The white noise source is then adjusted until the unit is producing a echoing of the sound. The result is a device which has hear Tesla's telluric waves.
Gregory Hodowanec "All About Gravitational Waves" or using Tesla termonology TELLURIC WAVES OR THE UNDERGROUND WAVES or in my interpretation THE GOLDEN WAVES.

ps. now you know about the stuff you have a deal in your passive rf-sniffer. The same Tesla technology 100 years old.
ps1. keep your Francoitaly LRL thread alive.
ps2. wainting with patience yours new infra-red lrl version.
