[Lowfer] AMRAD E-Field Probe VS Loops

[Dick Goodman]

Gang,
 
    I have recently rebuilt my AMRAD E-Field probe and feel that it is
working quite well. I have also thought several times about building a
shielded loop, in particular, VE7SL's loop detailed in the link below:

    A couple of parameters in reference to my current E-Field probe are
shown below. These stations were received from Mechanicsburg, PA. at 9:30 AM
local time. Receiver used is the SDR/IQ running WINRAD Plus:
 
    WWVB (with tunable preamp turned on)

    The 24 KHz signal from Cutler Maine (no preamp)

    Any opinions in reference to sensitivity & performance of my system
would be appreciated. Are these parameters valid in reference to determining
benchmarks in system performance? Do you think a loop would improve things?
