1. Topband: 160/80 antenna (score: 194): Author: richard at karlquist.com (Richard Karlquist); Date: Thu Aug 7 05:29:33 2003; You don't need a trap. If you top load the vertical so it is resonant on 160 as a current fed antenna, it will also be resonant on 80 as a voltage fed antenna. You can band switch at the ground.

The only possible advantage I can think of would be lower characteristic impedance, but since it is easy enough to build a g; /archives//html/Topband/2003-08/msg00046.html (7,561 bytes)
4. Topband: EchoLink (score: 194): Author: richard at karlquist.com (Richard Karlquist); Date: Thu Jul 31 14:00:16 2003; Rather than that, what I would like to see is more activity on 80 CW. If conditions on 80 are excellent, then you could try to QSY to 160. If 160 is not open, at least you have some 80 meter QSO's.; /archives//html/Topband/2003-07/msg00128.html (6,361 bytes)

I used 3 foot spacing so it would work up to 40 meters. The wire was 16 gauge tinned bus wire from I; /archives//html/Topband/2003-06/msg00022.html (8,212 bytes)

I added 20 dB of gain to the 8 MHz IF. This was very helpful on 10 and 15 meters, especially; /archives//html/Topband/2003-06/msg00072.html (10,429 bytes)

(score: 194): Author: richard at karlquist.com (Richard Karlquist); Date: Thu May 1 16:48:01 2003; The Anzac AM(C)-132 and AM(C)-134 amplifiers have 3OI of +49 dBm with a power dissipation of 2.6W.

8. Topband: preamps homemade ... (score: 194): Author: richard at karlquist.com (Richard Karlquist); Date: Sun May 4 19:59:47 2003; Right on both counts. The Anzac catalog specifically states that 30I is referred to the output. That makes sense in light of the fact that the 3OI's of the two amplifiers I mentioned are about the s; /archives//html/Topband/2003-05/msg00025.html (7,854 bytes)
9. Topband: Low RX Dipole (score: 194): Author: richard at karlquist.com (Rick Karlquist); Date: Mon May 5 20:52:55 2003; I'm wondering if I find that a dipole or inverted vee, whether high or low, is virtually always a better RX antenna than a vertical, on 160M and 80M. Sometimes it's about as good as a beverage. I rou; /archives//html/Topband/2003-05/msg00034.html (7,200 bytes)
