*The offending noise is all ground-wave. Locally generated, ranging from a little over a wavelength to a couple miles away. Seems like most folks assume the offending signals are sky-wave. But rememb

Has anyone built and tested the "Delta" RX antenna promoted by K6SE for use at FO0AAA? I am interested in performance reports from others. The "Delta" is extremely easy to build and requires only a s

Here is an update on the ongoing ground-independent RX antenna work I've been doing. First of all, let me thank those who responded to my request for info on the "Delta" configuration. The inputs wer

After reading Gary's comments on the loop family antennas, I realized that I had left out one bit of information regarding the "Delta" performance. It seems that most of the delta performance degrada

Since KMIK (as in MIcKey mouse/Disney), 1580 KHz, puts +5DBm out of the coax on my topband TX antenna, I feel that my experience in this area might be worth a little bit to someone. Notch filters of

After swapping ISP's, I updated the Rotatable Flag info as well as the rest of my web page. I have included transformer data and a "preamp" schematic this time. See it at: http://home.earthlink.net/~

Geo, In my albeit limited experience, the small diameter cores (0.5 in and less) prohibit a large enough wire size to insure reasonable survival. Lighting and close proximity to TX antennas, even tho

With the local temperature finally under 95F, it's time to work on low band antennas. During the middle of last season, I noticed the "Rotatable Flag" RX antenna performance dropping off. Towards the

Tom, This appears to be an excellent solution to the preamp part of the problem. I have had great success with the single-ended CATV preamp I've used for the last twenty years or so, but would like t

A question for those more versed in communication theory than myself: Through the years I have tried, in vain, to correlate receiver test bench data with on-the-air performance. I guess that personal
