Provided that certain conditions are met, like flat land. :) Make the land non-flat, and modeling becomes FAR more complex. At VHF and UHF there are multiple complex propagation mechanisms at play,

Hi Neil, the DXCC, continent, CQ, and ITU zones are determined from the callsign by looking up the AD1C CTY.DAT database. The grid is not used for that. 73

Hi Hasan, We completely agree! Your 800 watts and 5 element LFA at 60 feet fed through your low loss hard line is about as good as it gets for 6 meter MS and Sporadic-E. My 70 foot boom 11 element

I don't believe so. Those contests have specific data items; the RTTY contest expects to find a state code entered, don't think it will handle a county code. Same with the VHF

It only appears on the RECEIVING station's program. The program uses the grid to show that. That station has a need to know where you're calling or answering from, you

The DE QSO party is coming up on the first full weekend of May. The exchange is as follows: Delaware stations send signal report and county. Stations outside Delaware send signal report and state,

First, let me say I am not an expert in antenna performance and have never had or used any antenna pattern software. However, I will say this: Somebody who only has access to a Moxon antenna should

Kai, I've been using the arcsin a/4*h formula for years. Of course, its results can be misconstrued to mean that the single number result (1st peak) is a line and not a lobe, and that's what I was

Thanks, Kai. and in general, I would suggest that anyone new to MSK144 and meteor scatter on 6 meters join us on Ping Jockey in the mornings. There is a lot of help there and many willing operators

I have that checked, but do not see anything after my grid.

So, motivated by this email thread, I'd changed over from my usual listening in on 20M FT8 while I work to 6M MSK144. Have the 5 element Yagi pointed west in the later mornings (9:30am-noon). Have

Frank, I'm in complete agreement with you. My point, apparently poorly made, was that there is no reason to uptilt a Moxon on 6 meters that is even 20' off the ground in attempts to get better MS

Hi Hasan, There are two components to the elevation pattern of an antenna over ground. One component is the free-space pattern (FSP) of the antenna. That pattern would be influenced if

Hasan, The 3 dB elevation beamwidth of a Moxon or any other Yagi is a primarily function of its height above ground. A 0.32 wavelength high Moxon has a 3 dB elevation beamwidth of 50 degrees. For

Chuck, That seems as if you are saying it is permanently compressing the audio input even when it is at a very low level. There ought to be a level below which it becomes linear. Strange. 73 Alan

Hi Joe, Antenna modelling answers your question quickly and easily! The very low 6 meter Yagi you showed is only about 1/4 wavelength high (9 feet) to produce a elevation pattern with 3 dB beamwidth

The 3 dB beamwidth of a Moxon is about 80 degrees, fantastic for broad azimuthal coverage. and its quite a good antenna at a height of about 10 meters and much better 15 meters high. A 50 degree 3 dB

Hi Rick, that information is added at the receiving end when "Settngs->General->Show DXCC, grid, and worked before status" is checked. It is derived from the callsign of the sender of the CQ message

In the standard cq message I have: CQ KK4GGL EL99 I notice that many hams have text after the locator, such as CQ Zone 31 or AF. How can I add the same type of text? Thanks.

Hi Bob, it's your choice, the checkbox "Settings->Colours->Highlight by Mode" determines which. You can change it any time you wish. 73 Bill G4WJS.
