One excellent example of use vertical array for HF on the beach was VP6DX Ducie Island 2008 http://ducie2008.dl1mgb.com/equipment/index.php Fantastic performance and results. N4IS JC ________________
Come back when you can actually give an honest and complete answer....for once...and stop trying to deflect the subjects. The Topband members would benefit. <<< Carl I really thing you are going too
Hi guys I would like to share with you what NX4D just found out. Doug has experiencing a strong noise on top band for almost a year. He did try to find it everywhere, disconnected all appliances in t
Mike The DX Windows dated few decades ago, from the time US stations used to transmit 1800 to 1810 and listening in the DX windows 1825 to 1830 , all because the band was packed with LORAN signals, t
Hi guys We have a new class of station this year, few but some European stations running contest from remote station in US using European call sign, not W4/xxxx or W7/xxx not even xxx/W4. Today with
Hi Saulus Yes, I did it, Actually you had one of the best signals from Europe all night long. You can see the HUGE difference, few US reports and lots of European RBN , some goods report from 2 US RB
Hi Jose That was me. I was testing my new RX antennas comparing signals from Europe during the contest . WOW you guys have the best site for 160m in Europe, I was impressed with the signal and the re
Hi Thor Thanks for the heads up I did now that the RBN is so unreliable, and I am very disappointed with RHR marketing proposal. EA7PP signal was s7 when most of Europeans just above noise. But you r
Hi guys I would like to commented on the subject of RX comparison Tom when you introduced the RDF methodology to measure directivity, you really hit the nail in the head. I'm working on RX antennas o
Hi guys Polarization does play a lot on 160m for two reasons. I can say that because I am using my HWF (two horizontal flags end fire) since 2009. The first one is local man made noise that propagate
I forgot to mention another very important development. My friend N8PR is experiencing with the WF in another level, Peter is using a rotator to turn the WF vertical to horizontal. He worked FT4TA on
Hi David and Don I understand your point. Gain is cheap and quite easy to get with a good low noise amplifier, but to keep the common mode noise out of it is very expensive, and could be very complic
Milt, Thanks to share with us your experience during XZ0A. When I started playing with the HWF I was surprised to hear XU7ACY almost every day between 11:10z and 11:20z SSW, during 2010 and 2011 , th
" Since Rick correctly stated that RDF doesn't account" Jim RDF is everything ! The RX antenna system is the only way to improve signal to noise ratio. All electronic device is not perfect and introd
Jim " What I am asking is if anyone has any, on-the-air experience and would recommend one antenna system over the other for *most conditions*. In other words, will an antenna that has a less lower e
Hi John What is the orientation of you low dipole? I assume similar to XZ0A it is broadside N-S. In 2010 the SSW SSE propagation that I am calling TELP started with solid copy for 2 weeks in October
Hi Dick "I never noticed any difference in receiving performance" That's exactly what we should expect using a resonant dipole, it interact with any other antenna because the fiscal length is resonan
Hi Jorge The most common problem of Passive Inter Modulation (PIM) that can flood your radio with BC harmonica is Aluminum Oxide. The dielectric on that white powder between aluminum and most every o
"An array of loops is two loops for two directions. Hi guys The simple solution that is working very well since 2009 is the HWF. Why not two horizontal loaded loops end-fire. Two identical horizontal
Hi Guys I uploaded the video on YouTube on this link, DropBox is not working. http://youtu.be/dNBekvzlxgM Hi guys The simple solution that is working very well since 2009 is the HWF. Why not two hori
