[ARC5] A hardly relaxing oscillator

[David Stinson AB5S]

    The neon bulb is there to prevent spikes from blowing the transformer primary.  If it's flashing, it's saving you.  If the receiver is motorboating, two most likely suspects are either a bypass cap open or, more and more common, you have a Hi-Z ground point somewhere.  Any chassis connection or screw is suspect.  In the last 5 years I have cured many  problems by finding every screw or binder that grounds something to the chassis by giving it a little "tweek." Last one was weak receive in a Mackey Marine receiver.  It was the screws fastening the front panel.  I normally go over all such screws and bolts first thing but forgot these.  One fractional tweek and the problem was cured.    .........................Sent from my cell phone.
