The guy who has the record this year, I believe, is Jim, W5JAW, in five hours! Incredibly, Jim did this with Low Power to a 12 FOOT VERTICAL !!! Can anyone top that?! Paul, K5AF In a message dated 12

Frank, I certainly can see both possibilities and pitfalls with remote receivers. The odd thing is that if SDRs were used at both ends of the conversation, you might be able to work DX any time of da

Gang, I just finished constructing and "hanging" my spiral top vertical antenna on a high tree limb. Here are some of the specifics: - 16 turns of #14 dull gray coated wire on a 4'x4' tophat, turns s

Fellow Topbanders, I've been pouring through the indexes for the last several years of Antennex, and was wondering if there was a consensus on this forum regarding the value of this media for topband

I've read a lot about the K6MM vertical and may be forced to go that route, as the Neighborhood Association has received some complaints on my current 160M dipole and I may be forced to remove it. So

Gang, I have a clear area about 31' by 31' to put up a short 160M vertical this Fall. I am planning on putting up a 40' top loaded vertical in the center of this box with an elevated ground system 8'

Jerry, The Cushcraft MA-160V vertical happens to be 35' tall. I believe there is a capacitance hat at 23' with an inductor of unknown value just under the hat. The hat spokes are 48" and there are 8

Many topbanders pull their radials up at the end of the Topband season in the Spring, and re-deploy them in the Fall. I've tried laying thin-wire radials and have had troubles with the dog catching h

Guy, Brilliant piece of work! I don't think we can fully comprehend or completely model all the factors involved in 160M operation. If this proves difficult in an open setting, imagine trying it in s

I'm also sure that you cannot equate signal strength between stations in the same general vicinity. I've heard and worked stations that others in the area couldn't, and vice-versa. Not an unusual phe

Before doing anything else, consider a more robust tuner at the base, that is a high-current area whether the antenna is 1/2 or 3/8 WL. A simple L network tuner with a #12 or #14 air-wound inductor a

The Heathkit Balun is not robust at all, the coils are close-spaced and made with #18 or #20 wire. I had one as a young ham in the 60s and was quite disappointed with the physical construction. I'd n

I've had very good success with a 24' end-loaded vertical dipole on 40M. I'm wondering how principles that I've used there might apply to 160 and 80M. First of all, end hats can be quite small and st
