Next few years might be full of such stuff. Time to figure out our 160m maxi-plans. 73, Guy. _________________ Topband Reflector Archives - http://www.contesting.com/_topband
Hi, Jimmy, If the question is whether laying a single 30 foot wire on the ground from a vertical feedpoint at the ground to the radial center is lossy, it is. For At least two reasons. First, a singl
Hi Gert, What you are suggesting, ** at 1.8 MHz **, even with 34 of those cores on a 1 meter length coax would have only a few hundred ohms blocking, not nearly enough blocking to do anything serious
With apologies to Tree, who has asked that this subject be dropped... The question of the effect of a remote receiver or receivers has already been dealt with by some contest organizers needing clari
Hi Terry, What is there about 80 meters that means it doesn't need a carefully done radial field? If anything, the low bands need "careful" worse... Your elevated radials will be hard coupled, like t
I actually wasn't hearing band peaks either, until I got to thinking about that, and went digging in the RBN stats. The peaks are there. So what gives? One of the human factors kinds of things that b
If one is not talking about ham implementations of the commercial AM BC paradigm and their big verticals over very well done dense radial fields, the models can do quite poorly. Go ask W7EL. But then
The RBN reports and filters are gone as well. Usually a break like this indicates a difficult upgrade, or some problem they haven't figured out yet, or both. Perhaps Pete has some inside dope? 73, Gu
I'd say that the screen fills from the RBN server have gotten a lot faster. Maybe some hardware upgrades? 73, g. _________________ Topband Reflector Archives - http://www.contesting.com/_topband
If one wants to get to the bottom of locally varied TX performance, the final answer lies with establishing a personal monitoring site. The problems with simple (aka cheap) RF field strength meters a
Yes, the real world on 160 is very complicated, and by some issues that seem, anyway, to be unknown to more hams than not. W8JI had a 160 dipole up at 300 feet and ran over a year's worth of A/B test
One can do better than 7 turns inside FT240 forms if you use RG400 for the winding and terminate the winding PL259's with UG175 adapters for the RG400. Choke made this way are near indestructible exc
The awards usually come with CW, SSB and digital as categories. What I see is FT8 displacing RTTY for awards, but not for contesting. What FT8 will bring is the ability to use daytimes on 160 and 80
Hi, Jim, The problem in your proposal is that the location of the relay must be the highest possible voltage on 80m. You need 20 kV maybe more at QRO. There is a better way to get 80/160 off the same
[The following is an edited and upgraded version of my direct email to fellow PVRC'er Jim, AB3CV] Hi, Jim, The difficulty with your suggestion is that the relay location must necessarily become a vol
Hmm, this last week was still hitting RBN over there, and worked G3OLB two different days a little before his sunrise. One of those was a long lovely old time 599 QSO with Tom, like I was working som
Howdy, all. <<<Introduction:>>> Peter's post here follows a direct inquiry some weeks ago that I was unable to fully answer before now. Wire mats connected to ground radials have been around a long t
Methinks hamdom underestimates 160 propagation in the summertime. Working DX through QRN and having reduced opening time during summer, these make working the DX irritating to the ears and inconvenie
During the last 15 mins or so of CWT, stations worked on 160 included: on the east G4UFK, not in test. on the west N6RO Western RBN's VE7CC, VE6WZ, NC7J, east spot (not RBN) ON7PQ. Don't sound like a
