Ditto that. Most of the noise I have seen from electric fencing is the arcing somewhere along the wire. Usually across an insulator but sometimes across a break in the wire at a crossover or connecti
Gary, The crater profile you are seeing is described in this link: https://interferencetechnology.com/spread-spectrum-clock-generation-theory-and-debate/ If you get nothing else from that link at lea
The typical HAMIV and T2X rotators have 3 separate systems inside them. A 500 ohm potentiometer to determine position, a motor and gear box to turn the thing, and a brake solenoid that pulls a brake
Took a stab at this while I ate lunch today. What does the model say? Earl N8SS _______________________________________________ _______________________________________________ TowerTalk mailing list
Old boy scout here too. Most common knots for ham radio applications I use are all from my scouting days. taut line hitch Boy scouts use them on tent ropes, hams use them for adjustable vertical ante
I think the previous posts have covered most of the possibilities. I would hazard to guess that the crud you are hearing is the main culprit and the 3rd harmonic of the AM station is getting the bad
Check R2 10k resistor and the 5k pot in the controller. Sometimes these get changed out to make meter indication right for some other application. Like a rotating tower or an elevation rotator. Earl
Terminating multiport devices in their characteristic impedance is desired when those ports are still part of the circuit. In the case of the antenna switch, which disconnects the undesired ports and
I concur. Have used Beverages on Ground and my favorite was a one wavelength on 160 that anchored to a ground rod at the feed point, sloped up to 12 feet (3 of those military fiberglass supports) the
I have done it two different ways with my last two QTHs on a 100' Rohn 45 tower with flat top section. 1) Tie the mast just above center of gravity to the lifting rope through the gin pole. Pull it u
The earliest AFCIs were notorious for false tripping. They worked on the principal that an arc generates broadband noise throughout the radio spectrum. They would listen to a slice of radio spectrum,
