61. Topband: 80m vertical (score: 1)
Author: Dennis OConnor <ad4hk2004@yahoo.com>
Date: Sat, 5 Sep 2009 11:40:57 -0700 (PDT)
A pole that size is going to be resonant somewhere near the top of the band...  Lots of "it depends" on what else is in the near field that couples with it... Stand it up, run a dozen radials out...

Do not connect to the fence... You are over thinking this... You will never be able to hear the difference between good enough, and 'perfect'... Put down the radials in the space you have and go oper

Subject: Topband: MFJ 259B on 160M I have not yet solved the riddle of setting the MFJ-731 filter to my satisfaction that it is not compromising the readings...  The 259 is a great instrument and I u

Thursday night had good conditions early on... I was looking for FT5GA so did not work the DX I was hearing (well, G3JMJ had a good signal and seemed to be having problems hearing so I pinged him for

Date: Thu, 1 Oct 2009 07:35:53 -0700 (PDT)
There are going to be a lot of angry ops when the FT5GA logs are final...  They think they worked Glorioso but worked pirates and jammers, not the island...  I listened hard on 160 the night we had t

Yes, there can be significant noise level differences between directions as close as 45 degrees apart... I see that with my Beverages which are all fed with coax...  A Beverage that points towards an

Author: Dennis OConnor <ad4hk2004@yahoo.com>
Date: Fri, 9 Oct 2009 05:55:49 -0700 (PDT)
There are two issues here... 1. Is your Beverage coax braid grounded at the antenna feed point? If yes, then you MUST switch both sides of the coax, center and braid, at your switchbox, and leave the

Author: Dennis OConnor <ad4hk2004@yahoo.com>
Date: Tue, 20 Oct 2009 05:56:45 -0700 (PDT)
John, Over ground that is more conductive, you install the Beverage higher, 12 feet or so, which will help preserve the pattern... Over non conducting media, dry sand, antarctic snow, you can lay the

Date: Wed, 21 Oct 2009 06:31:22 -0700 (PDT)
With the loop close to the transmit antenna, noise coupling will be a problem... Only a few solutions come to mind immediately.. One would be to relocate the loop so that the transmit antenna is in t

As if we don't already have enough problems with fish net beacons, harmonics from AM broadcast, and on, and on... Nick, why are you cluttering our 160 band with useless beacons?  jeez!  denny / k8do

Author: Dennis OConnor <ad4hk2004@yahoo.com>
Date: Thu, 22 Oct 2009 05:36:25 -0700 (PDT)
K4M has good operators, reasonable antennas, and a reasonable signal...  Easy enough to work them, if you have taken care of business on your end... FT5GA did not have propagation... I listened hard

73. Topband: The East Coast Advantage (score: 1)
Author: Dennis OConnor <ad4hk2004@yahoo.com>
Date: Thu, 29 Oct 2009 05:06:21 -0700 (PDT)
Given the propagation characteristics of Topband along with the uneven distribution of DX entities, it is not possible to make a level playing field for the East coast versus the West coast under the

To my fellow hams working TX3A this morning, I am not the lid I appeared to be...  The radio got a bug in the CPU and kept jumping back to 1830.2 every time it was keyed...  My apologies...  Details

I have long runs of both 600 ohm open wire line and coax... I have runs of coax out to a 1000 feet that on 80 meters and to 1500 feet on 160 meters... I do not find the coax losses to be a problem...

I hear you on Eddy and there is no deficiency in your signal... My opinion is that interconnecting radial systems is a waste of time, if not a mistake... And for those who believe in interconnected s

OK, I'll bite... Why would you put up a 5/8 wave vertical?  Have you modeled this dog? Now, I suspect you are talking about an inverted L - as the 5/8 vertical is 340 feet...  This is an even bigger
