. . . what do you mean by S5 reception . . .

A communications receiver equiped with a signal strength meter was used to measure the e-field on the short vertical wire connecting the helical resonator to the elevated capacitance. S5 is the signal strength that was read on the meter.

. . . at 1000 meters?
. . . and at what distance from the transmitting coil?


1000 meters is the approximate distance between the two ground connections.

. . . What kind of power levels could you receive . . .

I have not yet worked out relationship between the signal strength as it appears on the S meter and the potential on the receiver's elevated terminal. Also, the current through the ground lead was not measured.

Are you using an SSTC in your experiments? Also, Does your receiver have an adjustable elevated capacitance? or do you use some other method of tuning?
