Hello HAMSci:

ARRL advised that you guys might have to ability to assist with something novel and different.  

1.  First off, pictures of the interleaved coil (2 parallel wires), and an SWR analysis of it.
Interleaved coils are attached.   This coil is also called patent 512,340 - if you wish to analyze it or have A.I. analyze it for you.   

2.  Secondly, the device will be biased with a resonant frequency that falls inside it's SWR curve using a MOSFET (coming from a low jitter signal generator) - and is meant to cause an electric field between the 2 wires.   The 2 wires are tied in series but laid out in parallel for this to happen.  

The coils are high capacitance and low inductance, so they are atypical.  

3.  Thirdly, the goal is to attempt to make the antenna more sensitive by picking up plasma wave perturbations from the ionosphere and beyond (Van Allen belts) & use the electric field in-between the 2 wires to detect them.   I have access to several dozen supercapacitors of 5.5 volts & 2 Farads, a TRX-DUO SDR, and a Rigol 1032Z signal generator.     Integration times of 600 seconds (10 minutes) for the slowest 1.7 milliHertz waves may be needed. 

The SDR cannot detect such a slow wave, but if it is multiplied by the modulation frequency applied  to the transistor - it will encode the signal as AM for proper analysis by the TRX-DUO.

How do you account for the effect that the Meade LXD-55 has on performance? Wouldn't the motors in the Meade change operating characteristics?

Happy April 1!

Um, nice identification of the mount.    But, I'm just using it as a holder.   The coil will be pointed at only 1 spot in the sky - not tracking.    it will not be powered.
