Re: Topband: 4SQ vs. 8 circle rcv

Paul, You may also want to consider a 3 element array, which gives you 6 directions. Check out the Hi-Z website for data on directivity of various systems- 3, 4, and 8 elements. Rudy N2WQ Sent using a tiny keyboard. Please excuse brevity, typos, or inappropriate autocorrect. > On Jan 12,

Topband: 4 square

Used both the 4 square and 8 circle array by DX Engineering. Both work but, in my thunderstorm environment, I spent many hours and as many dollars as the systems originally cost repairing them over three seasons. This is despite keeping the systems powered off, except when being used. The guys

Topband: Update on 1814 kHz mystery signal

I received a number of replies on the subject of the mystery CW/QRSS signal that I've been hearing every day on 1814.0 kHz. It's strong at my QTH just west of Boston. Most people don't hear it and some do hear something but I don't think it's what I am hearing. Here is some additional info.

Re: Topband: Topband Re: Ground Screen Question

Hi, Bob- I'm really seeing two or more issues here. There has been some debate as to whether or not tying in a ground screen to elevated radials is a good thing or a bad thing. I'll leave that discussion to other topbanders who have a lot more experience in that area. My understanding is that

Re: Topband: 4SQ vs. 8 circle rcv

Hi Guys, I have just updated my antenna comparison chart with some enlightening plots that show antenna comparison in 3D. Interestingly enough my experience is as you get to the higher RDF antennas each dB seems to be very important. Frank is quite right , One can never have enough receiving

Re: Topband: 4SQ vs. 8 circle rcv

Hi Mike, Beverages, four squares and 8-circle arrays are all excellent receiving antennas. Based on much on the air experience, my W8JI passive 8-circle BSEF arrays have much narrower beam width than my 580 foot Beverages and especially compared to the broad beam width my full size

Re: Topband: Strange propagation

I am sure that this is someone remoting. Nothing wrong with it, in my opinion. They can legally use their own call assuming they are licensed to be where they are, which isn't hard on 160M. And its no different than someone operating from their second home which many ops do. Its just way more

Re: Topband: Strange propagation

In the case of the RHR guys, they are constantly traveling to their remote locations doing tower and antenna work. That's what they do. Maintaining their system requires traveling and time. Ray is about to get his pilot's license any day now and he will be flying out to his remote locations

Re: Topband: Strange propagation

I believe Tree's main point was the station in question was 2 hours after sunrise at his qth on 160. I heard the same station. On Wed, Jan 13, 2016 at 4:14 PM, Louis Parascondola via Topband < topband@contesting.com> wrote: > In the case of the RHR guys, they are constantly traveling to their

Re: Topband: Strange propagation

I will say this: operating a remote station (for money) owned and managed by someone else will never be as satisfying as operating your own station, built by your hands. But than again, if you have no station, and are unable to build one up, what's your choice? I built (and rebuilt) a

Re: Topband: Strange propagation

Ed N1UR said "It seems non-trivial to me as to how to maintain these remote stations." My guess is it was someone using the Portland, OR station in the Remote Ham Radio network (http://www.remotehamradio.com/the-stations/). The stations are available for a price. I don't know whose actual

Re: Topband: 4SQ vs. 8 circle rcv

According to what I read there, there is little difference between the two. That seems odd. Was some information left out, or did I read the wrong .pptx file? 73, Mike www.w0btu.com On Wed, Jan 13, 2016 at 1:23 AM, Bill Hider wrote: > This presentation is titled: "Receiving

Re: Topband: 4 square

Thanks Tim. I should have done my homework. Now I have 8 580’ terminated beverages with Array Solutions transformers and terminating resistors. They are quite robust but when the warmer, less stable weather comes I disconnect both ends of each antenna to protect the hardware. Even so the odd

Re: Topband: 4SQ vs. 8 circle rcv

Based on the RDF metric, which is a very useful way of comparing antennas, the differences between the "best" arrays is not that great--maybe 1 to 2 dB. I have used Beverages and a number of different receiving arrays, and found that in practice it is very hard to discern 1 dB RDF differences

Perhaps, later in the declining sunspot cycle, there will be a remote duct in Hawaii. :-) 73, Steve NN4X > Message: 1 > Date: Wed, 13 Jan 2016 10:38:40 -0600 > From: "Joel Harrison" > To: "Tree" > Cc: "160" > Subject: Re: Topband:

Topband: Remote receive antenna selection on topband?

How do the big remote stations handle receive antenna selection? I will be doing my first ever remote operation this weekend for NAQP SSB, and I have a hack at home, where I use the "Stereo" output on parallel port from N1MM to drive a relay to select one of two receive antenna directions. But
