I thought the proper way of indicating clicks is with the signal report - 579k. I haven't heard this used in years. No one does that now, and they especially will not do it in a contest. Remember all
And I DID contact each of the guys whose calls I cited during the contest. In fact, I contacted about this issue two years ago when he was making a mess in the JA window during the winter Stew, and t
There are several legal-limit contest stations within a few miles of me and I'm used to a strong-signal environment. And how it can pump AGC causing audible artifacts that are not in the transmitter.
If your amplifier uses automatic bias, it can cause clicks. There are two things that will prevent or minimize this. 1.) Any auto bias system should not fully cut the tubes off. The tubes should stay
In W8JI's very rural area minimum main lobe beamwidth is more valuable to him than minimum sidelobes. Tom's choice of 330 foot broadside spacing in a very rural area with little or no local RFI makes
Hi Frank, I used a pair of 270 foot spaced broadside 580 foot Beverages for several years but the improvement was insignificant compared to a single 580 foot Beverage. I replaced them with single 900
"Phase inversion" is a long used term for inverting the phase of any signal. It appears with discussions of push-pull amplifiers, and it is equally used in RF phasing systems. Phase inverter and phas
The "Wullenwever" antenna was never a low-noise high performance antenna. It was simply a system designed to find direction over a very wide frequency range. The multitude of elements increased bandw
Out of curiosity... with so many narrow-pattern receive antenna configs, how do typical contest stations check different directions after a CQ? Frank, I still want to come visit your station during a
Questions about so called "water proof" connectors came up etc. As a result, I will include a few things which should be good practice because I discovered, for example, that everyone does not tape t
It was simply a system designed to find direction over a very wide frequency range. The multitude of elements increased bandwidth, but the physical width in wavelengths is the primary determinant of
So put you're receive antenna hat on. We suspect the ground is the problem. We are located on the shore of Victoria Lake at a resort. The soil appears to be sandy but with fresh water lake nearby. 20
I have been wondering if the antenna element in phased arrays could be a loop rather than a vertical. My thinking is that the loop has some level of directivity so phasing two of them should result i
A detailed analysis of the VE3DO Loop is on my web site: http://www.ok1rr.com/index.php/antennas/8-the-ve3do-receiving-loop A NEC file for further investigation is available via email upon request. T
Thanks for the insightful reply. Looks like there is no free lunch here- I can't get better performance by simply using a different circle array element. Bummer, I will have to stick with the vertica
My question for this astute reflector is whether there is any reason multiple receivers can't be connected to the array - listening in the same or different directions. Simply by multiple layers of t
I want to correct this: I experimented here with very large arrays years ago by watching signals and watching phase, and I found skywave 160 signals commonly have phase and level variations between a
Not so. Time to put this misconception to rest. Read my description of K9AY Loop operation in the most recent ARRL Antenna Book and review the description of a DF loop with sense antenna in that, or
It's the reference to termination resistors in the SPX data sheet that bothers me. Tom G3OLB You mean this part of the SPX data sheet that screams "dummy load"? :-) "Tower guys are made of tough poly
Forgive me, please, if I'm re-hashing a bit of the "...same-old, same-old" here, but I am really curious as to any "real world" experiences that might be out there in the matter of elevated radials,
