What is he using for an antenna on 160? He was consistently louder than any other DX this weekend at my QTH (near DC), and louder than many domestic stations as well. 73, Pete N4ZR Sometimes a tower
Operator was heard to say on 15 today that they would be alternating 80 and 160 tonight. No other specifics heard. 73, Pete N4ZR Sometimes a tower is just a tower
NASA was doing some research on coupling between severe thunderstorm activity and the ionosphere above the storm areas, but I don't recall any data or conclusions. 73, Pete N4ZR Sometimes a tower is
Kazimrovsky et al seems to be mainly a catalogue of questions that still need to be answered. The paper is available at http://eos.wdcb.ru/transl/gma/9503/pap01.htm There are a few additional resourc
On the other hand, if the SWR minimum is adequately low and the SWR bandwidth sufficiently broad, does it matter much? I had endless frustration with my much different tower trying to do what Ford su
I wouldn't hold my breath. At one point K2GM, an enthusiastic contest op, was either trustee or at least a principal operator. I remember visiting the station with him back in the 1980s when he told
This stuff was extensively used in Wang computer and word processing networks during the 80s. I bet there are still spools of it out there someplace. I'd start with E-bay -- one trade name was Twinax
I think I may have confused things by throwing the trade name "Twinax" into the equation. The stuff we used with Wang computers and WP gear was more like 2x RG59, 2 1/4 inch coaxial cables in one mol
Well then, I guess I share Tom's confusion. You did state that verticals would be the antennas of choice in NA and EU, based on the amount of insertion loss for a dipole. It seems reasonable to ask,
And thanks also to Bill for pulling it all together, for those of us who were hanging on to the topic by our fingernails. Is this effect entirely absent at 80m, or just very much reduced? 73, Pete N4
I have a 104' shunt fed Rohn 25 tower that combines the complication of a mid-mounted tribander with feedlines for a K3LR/W9LT lazy vee dipole array coupling to the tower at about 45 feet up. A serie
If this is the usage on 160, I can only reply that it is unique to that band. On other bands "tail-ending" refers to attempts to drop one's call in *before* the next round of calling begins, and can,
But don't expect to download them, crank 'em up, and immediately get meaningful data. There is a huge learning curve, as befits a very complex subject. Even when you understand all the output modes (
The thing that rang my bell most was the fact that you will be able to run very narrow roofing bandwidths on the main RX, which should really make a difference in contest conditions. Unless you're re
.... Why wouldn't it be even more cost-effective to buy something like the Icom IC-Q7A dual band handi-talkie, with 78-330 MHz AM receive capability built in? AES advertised this tiny little thing in
work with it that the MFJ259B is quite sensitive to BC band and/or any other "strong RF" coming in off the antenna in question. I do not live particularly close to BC stations but was getting strange
In my limited experience, these work great if it really is a discrete source, like the infamous thermostatically-controlled dog dish. They tend not to be much help if the noisemaker is up on a pole c
