I was always told that, if one had a 4 square, there would be no need for a receive array. I am finding this to be untrue when looking at the list of RDFs. (Receive Directivity Factor) I have snooped
I know this has been Discussed Out, but I just want to ask why the window is in the 1840 area instead of the 1990 area? They are asking for QRM at 1840. It will be a losing battle during contests. Ju
There was a QEX article in 2016 that examined ground mounted verticals. http://www.arrl.org/files/file/QEX_Next_Issue/2016/March-April2016/Zavrel.pdf Chuck W5PR Sent from Mail for Windows 10 This plo
When it rains it does not always cause rain noise, but when it does, the solution is to listen on the lower antennas. (You can still transmit on the top antenna.) Chuck W5PR _________________ Topband
I would not use any inductance unless the tower naturally resonates above 1800 kHz. If I were going to use a cage for the gamma connection, I would make a small cage that would only be on one side of
The choke bleeds off static charges that accumulate on the vertical. While I have witnessed noise from huge static charging to a 32 foot vertical mounted on the roof of the engineering building at Te
I think I understand much of what you are saying, but I know that I was on 160 meter FT=8 two nights ago with the speaker up fairly loud. I only heard noise. I set the AGC off and adjusted the RF gai
Ok, ok. I said it wrong. When I think of 160, I say night, It was about 4:00 pm local time. Chuck W5PR _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
Unfortunately, most are just deleting the conversation without reading it like I usually do, because of the title... Chuck W5PR _________________ Searchable Archives: http://www.contesting.com/_topba
Was the 1" OD cut into 2 pieces 4' long? One sticking out the top and the other inside the 1.25" OD at the top joint to stiffen it? Or 2' each to stiffen both joints? Chuck W5PR _________________ Sea
Wouldnt you connect the secondarys in series and the primaries in parallel? Chuck W5PR _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
I would think that FT8 is a mode uniquely able to operate through such interference. Chuck W5PR _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
In the Houston, Texas area the hams know the cell number of the guy who works for the electric distribution company locating the noise sources. We can call him and leave a very detailed message about
When I tried a BOG compared to a Beverage, I found the BOG to be almost useless compared to the Beverage. I would put up one of the arrays K9AY, SAL-30, 4sq rec, etc. I don't think you will be happy
Your results of the order of performance of these antennas are somewhat different than other, published results. I wonder if the composition of your ground would have something to do with that? Good
I previously had 4 Beverages with 3 of them being about 300 They definitely worked! However, the 650 was better On my new property, I hope to compare Beverages, SAL-30 and an 8 circle. First, I have
I wasnt intending to slight what you said either, I do think I misinterpreted it though. At this moment, the SAL-30 is certainly my best receive antenna as well. I would not enjoy working 160/80 mete
I seem to remember someone saying the modelling programs are unreliable when a wire is close to the ground. Also, there is really no way to model the properties of "ground." It can vary in just a few
