Is anyone here also experiencing this? Here's another one. It is now 2:30 PM CST January 17, and the post below, sent two days ago, just came in within the last hour. I'm trying to determine whether it is my e-mail provider or the contesting.com server. About all that comes in on this yahoo.co

Topband: "Grounds" for a Beverge

2011-01-17 Thread Charles W. Shaw
Howdy from NM, It appears to me that once more the term "ground" has led someone astray, and most likely it was some of us old time Topbanders that caused it. Mark, WD4ELG, recently said, "I thought bev worked with poor ground." In one sense, most of us would agree--a Bevera

Mark, While "The Benchmark Beverage" makes interesting reading, it conflicts significantly with years of practical Topband experience. The credibility of "The Benchmark Beverage" suffers badly because its based entirely on an undisclosed computer model not benchmarked to the measured performanc

Hi All, I'm sure that the Epsom salts trick works well, but seems to require quite a high level of maintenance. At my remote Rx site I use multiple ground rods to terminate my Beverages. I find that using 3 rods, then bringing the termination resistance back up to the 500 ohm that it should

Just a few comments to Mark WD4ELG: I too have a single short Beverage, about 350' over clay soil and sloping up a hill to the west, fed with about a quarter mile of RG58. It's really too short for top-band, but it does work. Myself and some other Gs have been carrying out daily long path test

Mark, I went back and studied Greg Ordy's page at http://www.seed-solutions.com/gregordy/Amateur%20Radio/Experimentation/Beverage.htm at length. From his chart and animated GIF, it appears that merely adding another 25 or 50 feet onto your 250' Beverage might do wonders for it on 160. (Having

When you first drive in a ground rod, it does not make contact with the area near the surface very well. The area near the surface is more important than what is happening farther down, as far as RF is concerned. I even poured some wet Epsom Salts down in the gap besides that rod. People will

First, thanks to ALL on this list who responded. I received more than 20 replies with suggestions and guidance. Second, I used my MFJ-259 to measure the SWR from the shack. I was shocked at what I found. Instead of 2:1 or less from 160-40, I had 8:1 SWR. This indicates a fundamental issue with
