Yuri, I don't think K3LR, W3LPL could afford that kind of property to begin with plus they have to work and have families and all of that. It is nice to do that kind of thing on DXPD's but I would no
this brings back a lot of memories..........i arrived on rarotonga a week after a French Dxpidition did, who was set up in the K2KW motel room with vertical antennas on the beach just as you would im
The link in the opening post of this thread shows an interesting, animated analysis of the elevation gains of a monopole, based on a NEC far-field analysis not including the surface wave. I then post

There is a lot more to winning an all band DX contest besides a great 160M location. Tim and Frank picked locations carefully for low noise, used the various tools to understand propagation and the a

Modeling programs are an excellent tool to calculate and predict some properties of antennas - radiators. What they do not "see" is the propagation mechanism after RF leaves the antenna. "Space wave"
Wow the more this thread goes the deeper the s**t gets, the first poster has no chance,, reminds me of a pig wrestling contest, you jump in and all you do is get is full of mud and s**t. Im heading d
A contest certainly is not only about transmit signal strength, nor is the lowest angle propagation always the most productive. There is always the 27 dB gain between the operator's ears (or lack of
One would think if there was a 10-20 db penalty, it would show on skimmers and that W2GD would be unbeatable being on the water. I'm sure I'm missing something. What is it I am missing? A contest cer
Anyone who is familiar with the San Francisco Bay Area has noted KGO's three AM broadcast band transmitting antennas located *IN* the water of the East Bay. From KGO's history page: "Three 300-foot t
You would think this would make KGO a superstation, however, my experience is that KGO's signal is nothing special. I used to listen to KGO and KFI (Los Angeles) when I lived in Seattle, and KFI, des
"Vertical on a beach" DXpeditions have a very different mindset about choosing operating hours and greyline openings, than other kinds of DXpeditions. Often they are also away from the RFI sources th
Also, KFI can be heard at noon in the SF Bay Area on ground wave, but the same cannot be said of KGO in the LA area. I would concede that KGO seems to have the superior ground wave signal across the
All,I am not very educated in these matters so I have nothing specific to add other than this: 1-We have some really bright "friends" who share the love of this exciting Hobby. And a true friend will
But skimmer, which displays a relative level, does not show the level difference. Skimmer shows about the same peak levels, but the stations closer or over salt water paths (not localized salt water
I looked at comparative data from four or five contests. I'm too far out of the path and in distance (approaching 1000 miles different) to compare, but I was still interested in how others in the NE
For Skimmer comparisons signals have to be on the air at the same time and the transmitting stations not to far apart from each other. In that case there is no statistical noise. But I would not expe
