Hi,

I looked at the Ross radial pins mentioned earlier and they are only 1 1/4 in. long. If someone were to accidentally catch a radial with a heel those little pins would come right out, at least in my soft ground. I use sod staples from agrisupply.com in North Carolina. They are 6 inches long and thicker than coathanger wire. They are bare steel and once they rust a bit, are quite difficult to pull out. If your ground (soil) is more dense, like clay, the shorter pins might work fine. I only bury radials when I run them onto my neighbors' property (with their permission, of course. I tell them what the wires are for and that they might help protect them from lightning.). Good luck with your installation and Good DX!

Kirk,  K9WW

I'm listening. Fingers crossed.

This one for sure. The child makes it special


That's the one we're leaning toward. His name is Ryan and he was a lot of fun, even though I'm pretty sure he called me Chicken Man in Marquesan all week.  Smiley

Nope, NOT here.  I tried for a few minutes last evening on 15 CW around the time Peter worked them, but no joy.  Today is a DAMNED JOKE, PLUS, for some reason all the bands are VERY noisy now.  Add the idiots, and its not fun.  I will hold up until next week, and hopefully the QRN will go away.  I can fight the idiots, but not while I am having trouble hearing the DX as well.

As someone else said here earlier, they are NOT very loud.  When I worked the XX9 on 10/29, they were quite a bit louder than the FT4 was/is, yesterday and today. (Go Figure......)  Usually, that part of the world is a chip shot for me, but they are weak on the dipole as well as the vertical.....(Huh)  Hope things pick up.  I know we have a cold front coming through tomorrow with showers and thunder, so next midweek should be much better. (I hope......... Sad)

I've seem some books like that, too.

There was a whole series where I recommended that, if someone had one, they might as well read it
since the pages were too small for wrapping fish.  Just don't take it too seriously.

In a standing wave antenna the current distribution along the wire is 90 degrees out of phase
with the voltage distribution.  That's because, at the end, the voltage is maximum and the
current is minimum (no current can flow in the open end.)  The ratio of the voltage to current
at any point along the wire determines the impedance.  In this case it doesn't matter whether the
antenna is resonant or not - the voltage and current distributions will still have same relationship.

But that is the standing distribution.  When the antenna is resonant, the instantaneous current
at any point is in phase with the instantaneous current.  Hence the confusion.


For example, in a dipole the standing current distrubution (the plot of peak current intensity) is maximum
in the center and minimum at the ends.   The standing voltage distribution is the opposite.  At the
feedpoint, with 50 watts delivered, you would have 50V @ 1A if the antenna is 50 ohms.  The current
and voltage delivered by the feedline into this load are in phase if the antenna is resonant.

At the end of the antenna the impedance might be 5000 ohms, so you would have 500V @ 100mA.
The voltage and current are still in phase, but we've moved to a different point along the standing
wave distribution (as seen by the change in voltage, current, and impedance.)


A tricky distinction!

I have a tribander that is popular with contesters.  Not surprisingly I worked them on the bands where I have resonant elements and gain (10m, 15m, and 20m).   I have no luck yet on the WARC bands.  This is proof that the extra few dbs of gain really count in a big pileup.

I'm hearing them now on 40m cw, but mighty weak.

Still about 1 1/2 hr to sunset here, kinda surprised to hear them this early.

Worked them on 40 m this morning quite easily.
He was very strong, stronger than all the LIDs and Tuners Upper, and DQRMers on his frequency.
Man, what a zoo!
I will look at SSB later, and RTTY at the end.
3 bands in the log in first 24 hrs is a very nice bag for me, and promises more Q's by end of exped.
73 es GL,

Now comes the difficult chore of deciding which photo to put on the QSL card. Which do you prefer?




This one for sure. The child makes it special. Both are good photos (maybe use the second one if you're doing a fold-out card, or cheaper ones for bureau QSLing?), but seeing a person from the location makes it better.

Either of these. Everyone and their brother has a coastline picture on their qsl card.

I would buy a used 590s before a new one.

[sarcasm mode fully engaged]

 Roll Eyes Roll Eyes i stand ^corrected^  Roll Eyes Roll Eyes 

we need an icon here that has a smiley face genuflecting  Cheesy

[disengaged]

i recommend a new one which comes with warranty, that new rig smell, and the a pending firmware update in January that will make it very SG-like  Wink  the most recently built 590s have the earlier bugs built out of them which brand new models tend to have... if you get an old one, try to find one made in 2014 (first digit of S/N is year, second digit is month)

You mean smell of a new old rig. Anything that goes wrong with a rig if it does is very early on. I have bought several used Kenwood and never had a problem. With a yaesu you might want warranty though. I have little doubt that some would have buyers remorse with new old 590 and wish they had spent bit more for new version. If you pay less than a grand for a used one you are less likely to be remorseful.
