I think TBDC should be left in the spot where it is, fills the hole in the 160 contest calendar perfectly. For those looking for additional activity around equinox there is Tesla Cup, has 160m catego
Appears that Milt's "fix" helped to maintain the Beverage properties better than the arroyo's "destructive behavior" by providing bridge for the discontinuity in the ground surface under the portion
I have been using "el-cheapo" version of this by using two radios, two antennas and feeding it into headphones and "my comparator" - my own scrambling brains. Even if not scientifically perfectly ba
Sorry Dave and other direct QSLers, I wanted to do nice commemorative QSLs for Tesla's 150th Anniversary, but QRL kept me busy and I wanted to combine them with this year operation. I realize that s
It will, just run piece of wire from the top of the coil to short mast on the front bumper (insulated). You should be able to tune the antenna on 160. I did that with my 80m Hustler mast and coil, b
Howdy Top Band aficionados, I have updated and moved the Top Band Records to new address http://www.k3bu.us/topband_records.htm please make a note and store it in your book. Also added is a new secti
Not exactly, peak could be typically plus/minus half an hour or more. 73 Yuri, K3BU.us _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contes
There is a difference between elevated and resonant radials that form the "other half" of the resonant antenna and ground "screen" against which the antenna or array works. Buried or laid on the gro
In view that you will be at the ocean front, the best thing is to use verticals. I would suggest to use two masts, top loaded as a T, to get advantage of low angle and salt water. Use two elevated r
Howdy Topbanders! I just talked to Opal, Jack's XYL and looks like Jack is beyond the danger, slowly recovering. They inserted two stems in his big top band heart and there is hope that he would be c
Howdy Lowbanders and Topbanders This year our ME lowbander gathering will take place in Glen Spey, NY: Here is a great chance for Lowbanders, Contesters, DXers and regular hams to have a great time,
It seems that beverage can work well close to salt water. Eu Beverage at VE1ZZ runs over poor ground (rocky terrain) and is terminated on the SS hub cap in the water. That one beats phased and stagg
"Small" problem, the atmosphere/ionosphere is not "your" mirrors. Making analogy or connection between them is silly, trivilializing and irresponsible. There is refraction, varying angles, "fuzzy mi
Don't get too hanged up on mirrors. There is also quite a bit of refraction - ducting going on especially on lower frequencies. See my article at http://www.k3bu.us/propagation.htm one time was poo-
Hi Sam, thanks for more info on the subject. Indeed, the atmo/ionosphere is a complicated medium, some dielectric, some conductor, some mirrors, some fiber optics, some clouds like blotches, some ni
I think that hysteresis might be at work. Just like we do not get the coldest, baddest weather around the winter solstice but a couple months later, this could be in play with RF and low band propag
No need for tuner. Just insert a coil, about 10 turns bewteen the bottom of the antenna wire and ground (radials). Connect your coax - braid to ground connection and find the tap on the coil for you
One of few things that W8JI has wrong on his web site. If you like to build effective small loop antenna here is my proven design. Get copper tubing bend it in a circle about 4 ft diameter, cut in h
Nothing unusual, IG9/IV3TAN was coming through S9 around 2 pm in VE1 land, not bad with "Italian 300W" and single vertical. Example of world propagation focused on Lampedusa, absence of D layer and
