It all depends upon the propagation and the TX and RX stations. A full size vertical in salt water will have a much lower angle at or near peak power than one miles back in the woods with typical gro
FWIW, here's a site where someone apparently did some tests. Someone posted it on eHam the other day in a similar discussion. http://www.k2kw.com/verticals/verticalinfo.htm 73, Mike www.w0btu.com ___
I wonder if they had read the report mentioned by Chuck Hutton a few days ago: http://downloads.bbc.co.uk/rd/pubs/reports/1968-45.pdf It would seem to shed some light on what they observed. There are
I quite agree, and from what I have personally observed, I WOULD NOT EXPECT peak levels on RBN to show the difference, except in very special circumstances. The Core Banks N4A test was walking backwa

Hi Guys K3ZM is my brother - and his 160m antenna is located in a salt marsh just to the West of Chesapeake Bay in Matthews, Va as I recall. Indeed he is located inland a bit (eg: not directly at wat
The signals showing the most change were not the loudest. They were the ones on the edge of the developing band opening. The stronger or peak signals from these stations would occur later as (presuma
I think that what is being suggested is, that if you have two signals, one S9 and the other right at noise level. The salt water advantage shows up more on the weak signal. Let us say both increase b
For receiving, an absence of noise sources in the path is all the difference in the world. As an example of this look at what N7JW and K7CA did from the Utah desert area. Utah desert is like the anti
A 3CX15000B7 or similar makes up for a lot of things and especially to those who always want to be on top in a pileup or contest. Carl KM1H For receiving, an absence of noise sources in the path is a
That makes no sense at all. What are you trying to say? A 3CX15000B7 or similar makes up for a lot of things and especially to those who always want to be on top in a pileup or contest. Carl KM1H For

Doesn't help you HEAR any better! Generally, on top band, even with my modest inverted- L with a few elevated radials, if could hear 'em I could work 'em! With 500 W. Best thing I ever did for myself
Nope but the RX antennas usually allow you dig a long way below the TX antenna noise. Most of the world isnt so lucky to have a selection of RX antennas or if they do the local QRN is too loud; anoth
If it was really 10-20 dB, shore locations would stand out like a sore thumb compared to inland locations. Everyone from around New England is about the same. Heck, K3LR is on the Ohio/PA border and
I am not a Skimmer expert, and am just asking. Question: Are all the Skimmers individually(and collectively) calibrated in concert? Can one rely on them for comparing scientific data and conclusion t
As far as I know, skimmers are not signal-level coordinated, so strictly speaking, it only makes sense to compare measurements made by the same skimmer. Although not an expert in this field, I have p
Juan, Am I wrong to assume that skimmers are not calibrated? They should be calibrated to S-9=50 uV into 50 ohms at least to provide some kind of uniformity band-to-band and skimmer-to-kimmer. I don'

Some long-time observations from about 55 years of AM broadcast band DXing MAY have some relevance to this discussion. That hobby has had a lot of simultaneous inland-versus-coastal signal strength c
I think the essence of what Tom has been saying is that yes there are some differences in a salt water location versus an inland location but that the differences are quite variable and are not "deal
