A fellow ham once was on a trip from Spain to the Caribbean on a sailing boat. For comms with me and some friends he was using a FT-900, and as a backup rig he could have used the onboard Icom marine
Topbanders, please comment on this : The feedline of a beverage is buried all the way from the feedpoint to the shack. There it goes up vertically about 5meters, enters the shack side by side with ot
Topbanders, thank you for the comments so far. With the initial setup the feedline crossed the entire run in the air, high enough to let even cars with antennas pass under it. After i buried the feed
Topbanders, I didn´t make many qso´s on topband in the cq-ww, but the single wire beverage at DL0WH has proven efficiency. I was called by a few na-stations and called a few myself. Obviousely, the K
Topbanders, ON4UN states in his book that the wires for a 2 wire reversible beverage must be installed side by side, but also may be placed one above the other with satisfactory results. Did someone
Topbanders, thank you all for your advice and suggestions over the last days. DL0WH spent about 10 hours in the contest , managed to log 48 qso, scored 23 us-states (that is almost half the WAS over
Topbanders, A fellow ham has a problem with noise on 160m. The band is unusable due to noise peaking 9+20 24/7. I think the source is a sensor lamp in his neighbours house. The neighbour complained a
Topbanders, i'm preparing DL0WH for the upcoming contests and will replace the single wire na-beverage with a two wire reversible beverage using twisted wire. According to http://www.w0btu.com/Bevera
Topbanders, i read the articles on w0btu's page over and over again and found the answers to my questions are right there. Just a bit spread (and in a foreign language). There is one question that re
Topbanders, i have a spool of twisted wire for military field telephone use, similar to WD1-A . It has some strands of copper and some strands of steel. I built the reflection transformer and install
Topbanders, thank you for your comments. Looks like this wire was a good choice (in fact, i couldn't resist as it was free), many use it for their beverages. Thank you all. Now back to the shop build
Topbanders, a fellow ham is setting up his station in V3-land and asked me to give him some hints on beverages. I'm far from an expert but fortunatelly there are lots here on this reflector. The loca
Topbanders, i'm looking for advice on automatic antenna matching. The goal is to automatically match a vertical for 160m and a loop for 80/40/60/(30)m using motor-driven variable caps. We are using m
Tim, thanks for fast reply. This is basically what i do with my own station at home. I control my steppir via network with the help of a raspberry. At our clubstn we have a microham setup, so why not
Topbanders, if crossing a driveway above ground is not an option, is ist ok to bury the beverage wire for, say, 20 feet? -- Ohne CW ist es nur CB.. 73, Martin DM4iM _________________ Topband Reflecto
No matter where the beverage points to, terminated or not, hearing only s5 static just seems not right to me. Did you connect your antenna to RX IN (not OUT) ? What XFMR do you use? Grounded the coax
Thanks to all. I had a few direct responses to my inquiry. I should haver better described the situation by expressing that it is not a driveway, but rather an opening in a fence separating 2 lawns.
Topbanders, for the construction of the beverage ( a 2 wire reversible beverage, that is) from my post a few days ago i wanted to know how to measure or determine the impedance of the open wire. I st

Topbanders, thanks for all the valuable input. So far i can say the beverage was of great help in the past 160m contest although it still is not optimized. At DL0WH, we didn't work much, we rather te
