Well said, Jim! Sounds like that "syndrome" you mention might be related to *Topband Disease* ;-) The link to that is now 404, but I have it copied to http://www.w0btu.com/160_meters.html near the bo
I've noticed that at http://www.dxscape.com/us160cw.html . Seems like activity is picking up, I'll have to drag my carcass out of bed some morning and join the fun there. :-) 73. Mike www.w0btu.com _
Not too long ago there was a good discussion about this. Try searching for DSL at http://lists.contesting.com/archives//html/Topband/ . 73, Mike www.w0btu.com _________________ Topband Reflector
This subject has been discussed here plenty of times in the past, and the consensus has always been that trees and other foliage near a 160m antenna has a negligible effect on the transmitted signal.
I *very much* appreciate the many replies to my post. I've known about the effect of foliage at VHF and above for a long time, but I think I've just learned something new and useful. :-) Since the ve
Bingo! Just because the military does (or did) something with antennas doesn't means it's good for us all to repeat. There was a discussion some time back that a Beverage must make a good transmittin
Hi Tim, Here's how I did it. http://www.w0btu.com/Beverage_antennas.html#transmitting_on_a_Beverage I left the termination resistor off, and it still had a 5 dB F/B ratio. I also connected the two wi
Am I? Okay. Sorry. :-) Nothing at all wrong with an experiment. But ONE of the things I was thinking of (but didn't mention) was a publication by the military (about transmitting on a Beverage) that
This is a VERY profound piece of advice! The RBN showed me that something was definitely wrong with my TX signal level this summer. It was considerably down from several other stations not that far a
That's exactly what I was thinking. Top load it and forget about a loading coil at the base. 73, Mike www.w0btu.com _________________ Topband Reflector
I'm not sure if there's a tutorial, but let me see if we call help a little. Since I probably have cookies saved from using them, you may experience something a little different. Click http://www.rev
Maybe I'm too easily entertained, but I think it would be fun to try 1500W+ through it on 160 sometime. Years ago, I did that with RG-58C/U on 10 meters. Just because I could. :-) Not that I plan on
Tonight was a perfect example of that. N2RK called CQ DX for the longest time, and he had a great S/N ratio from multiple stations on the RBN, including GW8IZR. I spotted him on the cluster, and so d
If I can add my $0.02 worth here... I have never found a better ferrite core for RX antenna transformers than the Amidon BN-73-202 (Fair-Rite 2873000202). I also used to use side-by-side stacked ferr
That is for sure. I was following a thread in an SWL or AM BCB group a few months ago, where someone (right or wrong) was recommending a toroid as an antenna in lieu of a ferrite rod with wire wrappe

P. 7-69 of Low Band Dxing (5th ed.) by ON4UN says a maximum of 4 turns on the low-Z primary for binocular cores. It might work, but there are other turns ratios you might try. Here is a list of turns
