other With an omni directional antenna on the transmitter, there may be several paths that are as good or better than what we call the "short" path, when we are talking about signals that originate f
or be it lead I would watch out for the losses in the feedline. RG-174 has almost 2db per 100 feet at a 1:1 SWR. Much too high. This is why using a pair of wires or open wire line is a better choice.
Connecting both shields together on the transmitter end should do nothing ... good or bad. The impedence of the coax shield is so high that there will be no effect on the ground/radial system. John K
I have four V80HD in an 80 meter 4 square and 13 V160HD ... four in a 4 square and nine in a large array. I have extended the 160HD to 110 feet by changing two of the 3 meter tubes to 6 meters. I guy

The DX window problem is getting worse rather than better. In the past, guys would slip in and make a few qso's before they were chastised and went away. Now they call CQ for hours and pay no regard
I understand a Company called Radio Switch Company makes large ceramic switches. Does anyone know if this is true and their QTH ?? I have tried internet searches to no avail. John K9DX
many 3 What you want is for the wires to assume the same potential as the tower, and that is obtained with coupling as tight as possible. Put them as close to the tower as you can. John
The rules I downloaded for the Pacific 160 test seem to indicate that VK stations do not get points for USA contacts ... they get a country multiplier ... but that is all. Does anyone know if this is
Regarding water in the box ... There is nothing watertight short of a true hermetic seal. When the temperature changes, a vacuum builds up inside the box and it sucks in humid air, that humid air con
Yesterday there was not a peep of VK9ML signals into Northern Illinois. Today he was copyable and workable through the QRN from 0900z to 1030z. John K9DX
Hi Everyone, A friend of mine suggested that I consider a tunable active (or passive) preselector to improve S/N on my broadband, toroidal fed 1500' terminated beverage. I use an FT-1000D with divers
Both KH2K/AH0 and A35VK leave the band before we get propagation here in Illinois. The band peaked great today with VK6HD S9, but by then they both had been long gone. John K9DX
The big Hiel headsets are terrible for hissing on the 1000's. I put a capacitors up in the earpieces and it got rid of it. Now I use the small cushion Heil headset, and it matches the Yaesu much bett
I measure 60 to 150 ohms for the round trip ..... two ground rods (8 foot) plus the wire. Some are over 1000 feet long and are still under 100 ohms. The resistance varies over the season. The soil is
Just keep adding them ... It will eventually stop changing...hi RE. the MP ...what you are seeing is not some non-linearity in the pre-amps etc, only the non linear action of the s-meter. Once the an
Likewise conditions in Illinois super. The "regulars" were over S9 and many others 579. I5JVA was 10 over S9 on SSB. But here at sunrise the conditions were terrible. NW, SW, all the same -- dead. Jo
