    IT's an Air intake...The chrome is the grille for the entry - the exit nozzle goes to the manifold.

    It appears to be a reproduction of a magneto reactance modial reactor. Depleneration of the marzal vane wane shaft is a never ending problem.......

    or ...
    How to enjoy amateur radio while buried in radio frequency interference desiderata

    TLDR version at the bottom :)

    Introduction.
    You can look up AF7XT on QRZ but all you are going to get is a condensed history of my motorcycle experience.
    You can look up "kopcicle" and most any random nonsense on the web and get even more nonsense.

    Purpose.

    I live in radio frequency interference hell. The only way I'm going to be able to operate HF amateur radio is with a remote receiver.

    Implements of destruction .

    A simple but robust general coverage HF antenna
    An SDR receiver as simple as a RTLSDR dongle or eventually an SdrPlay something.
    A simple single board computer with a USB port for the dongle and CAT5 for the POE/WAP
    POE , power over ethernet to a 2.4g wireless access point
    An antenna (or two) . A vertical gain antenna composed of stacked half waves at approximately 18-24Db gain.
    -A parabolic antenna with approximately 24Db gain.
    -or both using the common "dual diversity antenna connectors"

    The above is simply a proof of design/concept, bucket of readily available parts just to see if this is feasible.
    There is always the possibility that the very concept is flawed or, I'm totally full of ****.

    The reason I'm here is , well, you can blame that on TJ. Actually I have the RF and computer side of things well in hand if not actually working. When last I checked I still had some buffering/lag to deal with still and may need to use a real time operating system and or more ram, and or I missed something somewhere.
    What I don't have is a way to power this collection of parts at a remote location . The total current drain is minimal but as we all know there isn't always sunshine or wind to charge a battery bank.
    Climate is what you expect and weather is what you get. That covers the wind generation.
    It's daylight or it's nighttime or there are clouds. It is what it is.
    I need a sensible method of getting DC from a panel or 6 to a battery and a way of getting single or three phase AC to a rectifier for conversion to DC to battery, and , have both inputs play nice.

    TLDR version: I want a remote HF radio receiver on a hilltop that I can push downhill via commodity 2.4GHz as well as control the receiver. I need help with the charge/discharge control.

    Okay I've rattled on long enough. Time for someone else's input.
